<p>Although the 1954 U.S. Supreme Court decision in the case of Brown vs. Board of Education declared state laws establishing segregated public schools unconstitutional, in 1957 Arkansas Governor Orval Faubus tried to prevent nine African American students from attending school at Little Rock Central High School (LRCHS). Faubus’ attempt to block access to the students, using the Arkansas National Guard, resulted in President Eisenhower using soldiers from the 101st Airborne Division from Fort Campbell, Kentucky, to escort the students into the high school. Even though all students, regardless of race, can now attend public schools, segregation in a different form is still very evident when considering Advanced Placement (AP) classes. The lack of students from underrepresented minorities is especially evident in AP classes affiliated with the Science, Engineering, Technology, and Mathematics (STEM) disciplines.<br>
The goal of this education and workforce development project was to develop an educational/mentoring/advising model to open doors to all students, regardless of socioeconomic background, who want to go on to careers in fields related to maritime and multimodal transportation. This goal was accomplished through knowledge transfer and mentoring partnerships established at the following institutions: 1) Village of Promise (VP) in Huntsville, Alabama, 2) LRCHS in Little Rock, Arkansas, 3) Philander Smith College (PSC) in Little Rock, Arkansas, and 4) the University of Arkansas (UA) in Fayetteville, Arkansas.</p>

<pre>The aim of the work is to redefine the rules for shaping the architecture of inland water fronts taking into account the nature of the location of the investment (place context, social context, economic and economic context); identification of threats and opportunities resulting from the new approach to shaping water fronts. Theses considered in this paper are:
1. The diversity of the character of the buildings of inland water fronts is determined by their location and nature of functioning as well as considerations of entering into the context of local architecture defined by a certain set of factors.
2. The presence of water in the city structure generates a specific, unique spatial quality.
3. The use of river networks to create transport corridors that entails economic and social development requires the need for appropriate organization of infrastructure that supports and stimulates the flow of tangible and intangible goods. The analysis of forms of architectural and hydrotechnical shaping of river front areas was carried out on the basis of studies on the existing state of development of quays and their values in terms of tourism, quality of local conditions (climatic conditions, condition and parameters of hydrotechnical infrastructure), and examples of design solutions for Western investments.</pre>
<pre>The area considered for consideration is the coastal areas of the Warta, Noteć, Vistula and Bug, together with technical infrastructure in the form of inland canals and hydrotechnical devices. The choice of this transport route was dictated by the potential possibility of including it in the European waterways system. The inventory of areas adjacent to the inland route in the East-West relation concerned the area of Germany and the Netherlands as directly related to waterways in Poland. The purpose of the study was to analyze the relationship between the built-up substance and natural space and draw conclusions as to how to organize similar problem areas in Poland. After becoming familiar with the state and form of using the values of the water fronts of inland waterways in Western Europe, an analysis of the degree of attractiveness of the Polish section of the route East West. The objects of interest were not only the form and possibilities of adjusting tourist attractions in the immediate vicinity of the communication route, but also the possibility of obtaining multimodal connections of this type of transport with other tourist centers in the country as a form of an additional offer to be used during the ship's technological shutdown.</pre>

<p>A new numerical model for the on-demand computation of optimal ship routes based on sea-state forecasts has been developed. The model, named VISIR (discoVerIng Safe and effIcient Routes) is designed to support decision-makers when planning a marine voyage.<br>
<br>
The first version of the system, VISIR-I, considers medium and small motor vessels with lengths of up to a few tens of metres and a displacement hull. The model is comprised of three components: a route optimization algorithm, a mechanical model of the ship, and a processor of the environmental fields. The optimization algorithm is based on a graph-search method with time-dependent edge weights. The algorithm is also able to compute a voluntary ship speed reduction. The ship model accounts for calm water and added wave resistance by making use of just the principal particulars of the vessel as input parameters. It also checks the optimal route for parametric roll, pure loss of stability, and surfriding/broaching-to hazard conditions. The processor of the environmental fields employs significant wave height, wave spectrum peak period, and wave direction forecast fields as input. The topological issues of coastal navigation (islands, peninsulas, narrow passages) are addressed.<br>
<br>
Examples of VISIR-I routes in the Mediterranean Sea are provided. The optimal route may be longer in terms of miles sailed and yet it is faster and safer than the geodetic route between the same departure and arrival locations. Time savings up to 2.7 % and route lengthening up to 3.2 % are found for the case studies analysed. However, there is no upper bound for the magnitude of the changes of such route metrics, which especially in case of extreme sea states can be much greater. Route diversions result from the safety constraints and the fact that the algorithm takes into account the full temporal evolution and spatial variability of the environmental fields.</p>

<p>Truck activity is logically connected to vessel activity at a port. In turn, vessel activity is also influenced by truck shipments. Although one might expect a direct and straightforward relation between these two types of shipments, that is rarely the case. For instance, many maritime containers carry consolidated cargos that have multiple and different final destinations. Also, different truck capacities, customs clearance and regulations play a critical role in determining the actual relation between these two types of shipments. This project aims at shedding light on the nuances of maritime and roadway flow relations by quantitatively analyzing the linkages between these two types of shipments.</p>
<p>The study performed a statistical analysis to determine the probability distributions of vessel and truck activity, and then explore the correlation of each activity with the other. The analysis yielded coefficients that function as explanatory values for specific truck flows.</p>
<p>The ultimate purpose of this study is to provide a clearer and quantitative understanding of the relationship between maritime and truck shipments, and by doing so, to provide tools to develop a system for managing trucks that maximizes efficiency for industry, while minimizing industry’s negative impacts on a region.</p>
<p>For this purpose, the study selected the Port Freeport as a case study.</p>

<p>The U.S. inland waterway system has more than 11,000 miles of maintained navigation channel, which carries a significant percentage of the national freight total. Maintenance operations, including dredging and lock and dam maintenance/repair, are important to ensuring the effective and efficient operation of the inland marine transportation system. This study specifically deals with maintenance fund allocation to these projects. It proposes a multimodal approach to formulate the waterway maintenance problem in a network that considers rivers, locks/dams, highways and railways. The random effects of channel infilling known as shoaling are also considered. Maintenance on locks and dams reduces the delay therein, the cost of which is also considered in the model. The solution identifies maintenance projects to fund with an objective to serve the OD demand and minimize the total shipping costs on the network. The model is tested using data from the Ohio River Basin network. The proposed model is effective, and the result indicates a trade-off between lock/dam maintenance versus channel dredging. A distinct feature of this study is its explicit modeling of the interdependency between projects in realizing the system benefits as well as the random shoaling effect. A drawback of the numerical tests is that it does not include railway and highway modes.</p>

<p>A novel optimization method is presented where ship hull geometry is embedded in a B-Spline parallelepiped regardless of the specific approximation of the hull (panels, mesh, surfaces). The optimization procedure deforms the B-spline space while the B-Spline moves smoothly every pre-mapped hull point. Moreover, the final B-spline transformation can be applied on a different geometrical hull approximation to accommodate various hydrodynamic solver input requirements. The paper presents an example where the new method automatically converted a standard bulbous bow of a yacht into an inverted piercing bow. The numerical results for the original bulb were validated with model tests. The bulb performance improvement was evaluated with potential (ν-SHALLO) and viscous flow (STAR-CCM+) solvers, which both show a 9% reduction of the total ship resistance at the design speed. The optimized bow shape can save energy and lower emissions.</p>

<p>Communities are socio-environmental systems that can be vulnerable to and adversely impacted by natural disasters such as floods, hurricanes, and storms which have long impacted human life and property. Over the past century, efforts have been made to mitigate natural disasters. Fluvial and riverine flooding from inland waterways is a primary cause flood damages to communities in the United States. Therefore, considering the mitigation efforts employed along inland waterway communities is critical when considering future resilience. Flood vulnerability and risk mapping efforts are focused predominantly on the hydrology and historically have not accounted for consideration of vulnerable populations. For years, policies such as those that facilitate home buyout programs have been applied to mitigate hazards impacts after floods in both inland and coastal areas. Home buyouts offer opportunities to flood-affected homeowners that meet certain criteria to relocate to places that are ideally at lower risk of flooding . The properties that are bought out are often converted to greenspace to further enhance mitigation of flood impacts and improve community resilience (Nelson and Camp 2020). However, home buyout and other such programs can potentially have unintended consequences in the neighborhoods where they take place. When enough residents relocate out of the community to other places, the social fabric (i.e., a network of interpersonal social connections) and the tax base of the flood affected community can be severely damaged.</p>
<p>The overall objective of this project is to evaluate the unintended consequences of flood mitigation activities (i.e., buyout programs) represented as community costs of measures such as residential home buyouts. This project aims to develop a model for calculating a Social Fabric Index (SoFI) using publicly available data that is both transferrable and scalable to help communities evaluate potential impacts to the social cohesion of a community when utilizing riverine flood mitigation programs such as buyouts. To test the model’s applicability and robustness, it was applied to a case study area and subjected to uncertainty analysis and global sensitivity analysis. While buyouts are used in both coastal and inland communities as a mitigation approach, this study is focused primarily on a case study of an inland riverine community (i.e., Nashville, Tennessee, US) because an inland community may have more alternatives for mitigation than coastal areas.</p>

<p>Transportation planners in coastal communities plan for future hazards and risks of sea-level rise (SLR), and often, they communicate risk in public meetings via PowerPoint presentations with charts as well as two-dimensional (2D) maps that visualize information using Geographic Information Systems (GIS) technologies. The project investigates the use of immersive technology to communicate SLR risk, including the development of an immersive three-dimensional (3D) model of the Waikiki neighborhood of Honolulu, Hawaii. According to the project’s original methodology, participants would have experienced the model using virtual reality (VR). However, due to the COVID-19 pandemic, the team pivoted to creating and implementing an internet-based survey instrument with embedded 2D charts and video of the animated 3D model. The flooding projections were derived from National Oceanic and Atmospheric Administration (NOAA) data. NOAA supplies the SLR Viewer, a screening-level tool that uses the best-available national projections to map areas vulnerable to current and future flood risks.</p>

<p>This spreadsheet provides the volume analysis calculations associated with the project. This project focused on exploring the potential feasibility to utilize other locations along the inland waterway system where “graceful failure” or planned breach of levees may be used as a means of flood protection for downstream communities and infrastructure. Spatial analysis techniques were used with development of specific criteria to screen national-level data sets to identify probable locations for such mitigative approaches. The criteria were primarily focused on identifying non-urbanized, non-developed land where intentional flooding for storage of flood waters would minimize impacts. Each location that was identified as a potential candidate was further evaluated for capacity for flood water detention. A consolidated set of areas were identified that could provide some storage capacity for flood mitigation. Additional engineering and localized analysis would be necessary to vet the areas for actual storage implementation. However, this study provides an example of an unconventional approach to flood mitigation on inland waterways which could reduce the need for disaster response and assist in transportation planning during extreme flood conditions.</p>

<p>The objective of this study is to develop a statistical profile of travel times for the Gulf Intracoastal Waterway (GIWW) using Automated Identification System (AIS) data. This study also analyzes the impact of several variables on system performance. The study focuses strictly on the main GIWW channel and does not include activity on any ship channel or tributary to the GIWW. The data used in this study are for 2018 and 2019.<br>
This report builds on prior work undertaken by the U.S. Army Corps of Engineers (USACE). In this analysis of the GIWW, the methodology used by USACE has been modified to account for differences in the GIWW from the rest of the inland waterway system.</p>

<p>Conventional methods to assess the quality of service on freeways are based on the comparison of a specific peak hour traffic demand to the capacity of the facility, which is usually measured at a single uniform bottleneck section. However, estimating the quality of service of one bottleneck section may not be sufficient to assess the performance of an entire freeway facility. A driver travelling along a freeway corridor may actually encounter multiple flow breakdowns at independent bottleneck sections, which affect the overall quality of service. This paper introduces a comprehensive approach that considers an entire freeway corridor as a system consisting of successive independent bottlenecks with different characteristics and can be used to estimate the optimum sustainable volume. The methodology is based on the Sustained Flow Index (SFI), which is defined as the product of traffic volume and the probability of survival at this volume. Optimum volumes of two real-world corridors are estimated based on the new derivations. The empirical results reveal that the optimum volume and the capacity of an entire corridor is less than those of its most restrictive bottleneck.</p>

<p>The Maritime Labour Convention (MLC, 2006) is of high importance as other Maritime conventions. It brings some obligations to the biggest parties in the maritime industry which are flag states, port states, seafarers supplying countries and seafarer employing companies. The MLC aims to provide&protect the rights of the seafarers and to maintain their highest standardized living&working areas on board ships by law. The port and flag states have been delegated to inspect the seafarers’ employment&working and living standards.</p>
<p>Following on the Maritime Labour Convention which was enter into force in August 2013, an established and well-operated risk management system has become compulsory in the ship management system.</p>
<p>985 of 2136 deficiencies, which have been detected by Australian Maritime Safety Authority since 20 August 2013, are related with the obligation in question.</p>
<p>From this point of view, it is explicit that risk management is of vital importance for the ship management system.</p>
<p>Herewith this paper, the aim is designated as identifying the expectations of the Convention from the ship management and determining the optimum numerical methods for the best operability risk management model in intense ship working ambience. The accuracy of the model results must be close to the gospel truth. Furthermore, the results have to be the same as in the real industry terms. Since, the effect of a minimum failure, even, may cause huge expenses in shipping industry.</p>
<p>Upon the conditions and criterions, the appropriate methods of operational research for risk management model onboard have been selected. Whether the model equiponderates the requirements or not is tested by scenario analysis.</p>
<p>All in all, it is proven that the risk management system established herein this study works properly; meanwhile, it is demonstrated that the aforementioned model may be regarded as a notable reference for ship management system.</p>

<p><span>The goal of this research is to better understand the evacuation of a coastal community, the Florida Keys. This will aid in the planning, mitigation, response, and recovery of this community when a hurricane threatens to destroy their homes. To achieve this, a model of the Florida Keys was built in VISSIM, a microscopic traffic flow simulation software, to experiment with different improvement strategies. This process will include collecting data about the Florida Keys, building the roadway network of the Florida Keys, calibrating and validating the model, modeling recommendations, and analyzing the outputs when impelementing the different improvement strategies. In addition to the current evacuation plan, evacuation by zone, the following strategies were modeled: flashing yellow signals, conflict elimination, contraflow, and emergency shoulder use. From this, it was determined that the modifications to the intersections with traffic control devices – flashing yellow signals and conflict elimination, did not drastically alter the evacuation process. Adding travel lanes reduced delay and travel time for both individual vehicles and the entire population. Ultimately, it was determined that emergency shoulder use would be the most effective recommendation to implement.</span> </p>

<p>The project objective was to develop an online course to be taught to the maritime and multimodal infrastructure community including: transportation planners, maritime planners, infrastructure managers, Civil Engineers, and Industrial Engineers, on the use of trade-off analytics as a tool to assist them in their infrastructure development, management and preservation decision-making.Modules of this course can also be packaged into online webinars for practicing professionals. This course was developed using existing trade-off analytics resources and maritime case studies developed for the course.The course uses Multiple Objective Decision Analysis (MODA) with Value-Focused Thinking (VFT) and Optimization and to structure complex program asset management decisions requiring trade-offs between conflicting stakeholder objectives. The course focuses on framing decisions, identifying stakeholders, developing objectives and value measures, generating alternatives, developing a value model, developing a cost model, evaluating alternatives, identifying uncertainties, analyzing uncertainties, and making meaningful trade-offs between cost, value, and risk. The case studies and examples focus on maritime and multimodal infrastructures.The course was developed and taught in an online program, the University of Arkansas M.S. in Engineering Management in Fall of 2019.The complete set of course material are available through the MarTREC website for use by instructors at other universities and continuing education programs.</p>

<p>Data set used for the report, "Large Scale Evaluation of Erosion Resistance of Biocementation against Bridge Scour and Roadway Shoulder Erosion". The purpose of the report was to develop an alternative approach for armoring the riverbed with biocementation through MICP to mitigate soil erosion. Long-term erosion exposed to outdoor environment, rainfall induced erosion, and accelerated erosion were conducted on MICP-treated samples to prove the feasibility of the MICP technique for potential applications in prevention of bridge scour and road shoulder erosion. The experimental work and discussion about the testing results indicated that exposing to outdoor environment could result in sharp decrease on UCS for MICP-treated samples. But the MICP-treated samples had better resistance to rainfall induced erosion. The bio-surface treatment gave significant help for cement-treated samples to resist accelerated erosion and water absorption, especially the multiple bio-surface treatments method, no erosion could be measured and 5% lower water absorption was achieved after the cement-treated sample was triple treated by bio-surface treatments. The pure MICP-treated samples were also good at resisting accelerated erosion and water absorption. Furthermore, fiber addition and multiple MICP treatments could improve their resistance. The maximum erosion rate of single MICP-treated samples reduced from 0.16 mm/min to 0 mm/min after triple MICP treatment cycles applied on the samples. Extra MICP treatments on soil samples improved the resistance to water absorption significantly. The triple MICP-treated samples achieved a 6% lower absorption than single-treated samples. All these results indicated that the bio-mediated particulate material based on MICP can provide an effective solution for problematic cases of sandy soil in prevention of bridge scour and road shoulder erosion.</p>

<p>The Mississippi River is a major part of the MTS and has been referred to as ‘America’s inland hydro highway’. It is a critical food security corridor functioning as a major trading thoroughfare for US goods and commodities to and from the rest of the world. The complex river system is considered one of humanity’s greatest civil engineering feats. However, the strain on the river system is only becoming more acute due to aging infrastructure and the impacts of climate change. Up and down the Mississippi River, new pressures are being put on the river, impacting the environment, wildlife, and cities and towns along the riverbanks. Of particular interest is the impact of these pressures on the creation of chokeholds and vulnerabilities to the food and agriculture supply chains. These supply chains are inherently complex due to their interdependency with critical infrastructure systems including maritime and multimodal transportation with the largest risk to agricultural trade resulting from age and inadequate or inappropriate infrastructure. It is imperative to close the infrastructure gap, which is not just a function of more construction; new developments must be smart and able to withstand increasingly hostile weather and elements of climate change as they age. Consolidating the evidence around the importance of chokepoints on the Mississippi River to food security and enhancing understanding of the nature of hazards and vulnerabilities are key steps in converting chokepoint analysis into policy and strategic action.</p>
<p>The pressure and strain on the water transport infrastructure along the Mississippi river is a serious and urgent issue that requires attention and action from policymakers, stakeholders, and researchers. The purpose of this project is to evaluate the benefits and climate vulnerabilities of the Maritime transportation system, focusing on port infrastructure, agricultural trade, and resiliency. The Port of New Orleans is used as the study site.</p>

<p>The main goal of this study was to produce and extensively examine biochar as a potential material for the <em>in-situ</em> adsorption of typical pollutants carried by the stormwater runoff from the transportation infrastructures. Biochar, a product of controlled pyrolysis of carbon-rich waste material is the best known for its adsorption capacity as typically used for agricultural applications. The individual source of organic waste material, and parameters of pyrolysis, such as duration, temperature, limitation of oxygen, etc., would influence its final properties, which will dictate the overall efficiency of <em>in situ</em> adsorption.Several waste biomas were used as a starting material.</p>

<p>Communities are complex systems subject to a variety of hazards that can result in significant disruption to critical functions. Community resilience assessment is gaining popularity as a means to help communities better prepare for, respond to, and recover from disruption. Sustainable resilience, a recently developed concept, requires communities to assess system-wide capability to maintain desired performance levels, while simultaneously evaluating impacts to resilience due to changes in hazards and vulnerability over extended periods of time.</p>
<p>In an earlier work, the authors developed a classification scheme to aid in identification, selection and application of community sustainable resilience indicators that can be tailored to a community’s needs in operationalizing the assessment process. These indicators were characterized according to whether they aligned with social, economic or environmental systems that are necessary for a community to achieve a sustainable resilience domain of survival, well-being, or full preparedness.</p>
<p>Of the critical infrastructure systems that support these systems and domains, transportation is arguably the most important. This is based on the premise that transportation is a means to an end, providing the mobility that enables a community to establish and maintain a social, economic and environmental fabric. Whether it involves an educational, medical, recreational, religious, work or other purpose, absent a safe and reliable transportation system, none of these activities can be satisfactorily pursued. Moreover, in times of crisis, transportation serves as a vital artery for enabling access to and egress from impacted areas.</p>
<p>The objective of this project was to establish and demonstrate a method for evaluating a community’s transportation resilience, such that if deficiencies exist, attention can be focused on mitigating those concerns. This approach was designed around the scenario of a river valley community exposed to the threat of a significant flood event, with the expectation that the methodology has the potential to be extended to assess community resilience to other natural and man-made hazards.</p>

<p>The U.S. inland waterways play a vital role in the domestic economy, but extreme weather events (e.g., floods and droughts) perennially threaten to disrupt their operations. Exac- erbating these concerns, climate change is expected to increase the frequency and severity of these disruptions in the future. However, despite these known risks, researchers have devoted little attention to evaluating the financial implications of climate change on inland waterway supply chains. Moreover, traditional financial valuation methods do not facilitate an accurate quantification of long-term risks associated with investments in climate resilient infrastructure, which leads to a systemic under-investment in resilience and adaptation.</p>
<p>Here, we develop a state-of-the-art, data-driven approach to evaluate climate financing strategies for inland waterways based on future costs of inland waterway supply chain dis- ruptions due to climate change. The approach combines recent developments in financial analysis, climate modeling, simulation, statistical inference, and economic modeling. With this methodology in place, we can then evaluate cases where investments in resilient, water- borne infrastructure can o↵er cost-e↵ective means of mitigating projected impacts of climate change. Our project paves the way for researchers being able to quantify the return on in- vestment from climate adaptation strategies based on economic impacts of climate change on inland waterway supply chains and can help policymakers better allocate funding for mitigating future supply chain disruptions.</p>
<p>The report is outlined as follows. Section 2 discusses the motivation for our research and delineates the specific goals for this project. Section 3 presents an overview of a novel financial framework that is better suited for quantifying costs and benefits of investments in climate-resilient infrastructure and discusses how this framework relates to current financial practices, with a particular focus on inland waterway developments. Section 4 details how we project future climate scenarios and waterway conditions. Section 5 discusses the economic modeling framework we use to measure holistic impacts of disruptions. Section 6 describes follow-ups to this project (i.e., Phase 2). Section 7 gives our concluding remarks.</p>

<p><span>Chapter 26 of the HCM6 suggests a procedure for the empirical estimation of freeway capacity, which is based on the direct estimation of breakdown probabilities for bins of traffic volumes. The paper expounds that this methodology is unsuitable to obtain reliable capacity estimations. The theoretical analysis of the deficiencies of the methodology is supported by empirical capacity estimations for twelve freeway sections in California. Based on the empirical results, alternatives for the HCM6 capacity estimation methodology based on statistical models for censored data as well as the distribution of pre-breakdown volumes are proposed and validated. Once the models for censored data is implemented to estimate a reliable capacity distribution function for the freeways, it is used to modify an existing ramp metering algorithm.</span> </p>

<p><span>The COVID-19 pandemic caused unprecedented disruptions in global supply chains and port operations, leading to congestion, delays, and container shortages. Governments implemented containment measures, affecting social and economic activity. Ports faced similar significant challenges due to shifts in demand, labor shortages, and supply chain bottlenecks. E-commerce surge and disruptions like the Suez Canal blockage further intensified pressures on ports. The pandemic's impact, coupled with other events, exacerbated challenges for ports and supply chains, triggering inflationary pressures. This research sought to investigate the impact of COVID-19 and other events on port efficiency and the global supply chain at major ports such as the Port of Long Beach, Port of New York and New Jersey, Port of Rotterdam, and Port of Shanghai. The objectives of the research included quantifying shipping volume, identifying trends, analyzing factors, and enhancing understanding for policymakers and stakeholders in building resilient supply chains. The primary finding of the research is that congestion in U.S. ports may have been attributed to consumer spending and unprecedented container throughput which overwhelmed the ports. In contrast, the Port of Rotterdam and Port of Shanghai maintained vessel dwell times more consistent with pre-Covid, suggesting process efficiency and resilience. The research results also highlight the vulnerability of U.S. ports to changes in consumer spending, leading to an influx of goods and overloaded ports, reducing efficiency and increasing dwell times.</span> </p>

<p>Data set and report with data descriptions and outputs, "Economic Impact of the Gulf Intracoastal Waterway on the States It Serves". The purpose of the report was to examine the economic impact of the GIWW on the five states it serves: Texas, Louisiana, Mississippi, Alabama, and Florida. This project involved several research tasks. First, researchers estimated the economic impact of the GIWW by looking specifically at the impact of the commodities using the GIWW in the relevant coastal counties in each of these five states. Once this task was completed, researchers then estimated the impact of the GIWW on other modes, modeling the possible adverse impacts that would result if the GIWW were to become permanently unavailable and shippers would instead have to use the next economically feasible transportation mode. Researchers examined the cost of shifting additional traffic to other modes of transportation.</p>

<p>Predicting the impact of incoming tropical cyclones on ports in terms of the number of days underperforming is crucial for the effective management of the ports. However, existing methods perform undesirably due to the limited data and the inherent uncertainty associated with cyclone trajectory forecasting. This study applies a recommendation algorithm to address these challenges by focusing on predicting port impact rankings instead of predicting the duration of port impacts, which is often inaccurate and unreliable. First, we have collected comprehensive features of ports and hurricanes in the Gulf of Mexican and employed a modular time-series regression model to determine the duration of port impacts due to tropical cyclones, leveraging vessel count data extracted from the Automatic Identification System (AIS). Inspired by the recommendation algorithm, we recast tropical cyclones and ports as "user" and "items," respectively, while the duration of port impacts represents their "interaction," offering an innovative approach to model and analyze cyclone effects on ports. The Factorization Machine (FM) is adopted to learn the relationship between features (i.e., ports and cyclones) and subsequently conduct the port impact ranking. Finally, utilizing the hurricanes Alex, Ian, and Nicole that happened in 2022 as testing cases, the FM-based model excels in prediction performance and robustness against uncertainties compared to the widely used distance-based method. This study aims to provide port authorities and other stakeholders with a trustworthy tool for informed disaster management decisions, thereby enhancing port resilience. </p>

<p>The purpose of this project is to estimate the performance of multi-modal supply chains that use inland waterway ports. This is accomplished by developing a method to fuse publicly available datasets including truck and marine vessel tracking data and lock performance data. The study builds on a growing body of research related to multi-modal freight performance measurement, specifically freight fluidity measures. Freight fluidity measurement attempts to capture freight system performance from a multi-modal supply chain perspective. In this study, we effectively combine marine Automatic Identification System (AIS) data with truck Global Positioning System (GPS) data. Both data sources track vessel and vehicle movements and can be used to determine measures such as travel times, dwell times, and other freight activity characteristics.</p>
<p>Two models are developed. These are referred to as the Multi-Commodity Assignment Problem (GMAP) and GMAP +. The GMAP model quantifies annualized commodities transloaded at inland waterway port terminals by fusing two mode-specific datasets, truck GPS and marine AIS. The GMAP+ model then assigns commodity flows to vessel trips. Additionally, as a data product, the GMAP and GMAP+ models are used to generate catchment area maps that depict water and truck flows for inland waterway ports in Arkansas. </p>

<p>Truck activity is logically connected to vessel activity at a port. In turn, vessel activity is also influenced by truck shipments. Although one might expect a direct and straightforward relation between these two types of shipments, that is rarely the case. For instance, many maritime containers carry consolidated cargos that have multiple and different final destinations. Also, different truck capacities, customs clearance and regulations play a critical role in determining the actual relation between these two types of shipments. This project aims at shedding light on the nuances of maritime and roadway flow relations by quantitatively analyzing the linkages between these two types of shipments.</p>
<p>The study performed a statistical analysis to determine the probability distributions of vessel and truck activity, and then explore the correlation of each activity with the other. The analysis yielded coefficients that function as explanatory values for specific truck flows.</p>
<p>The ultimate purpose of this study is to provide a clearer and quantitative understanding of the relationship between maritime and truck shipments, and by doing so, to provide tools to develop a system for managing trucks that maximizes efficiency for industry, while minimizing industry’s negative impacts on a region.</p>

<p><span>Connected and automated vehicle (CAVs) technology has the potential to improve traffic efficiency and safety by providing advisories related to different traffic, road, and environmental conditions. Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communications are two key communication systems of connected vehicle technology. Previous research focusing on the use of CAVs technology during evacuation period lacks examining drivers’ behavior in such situations. Therefore, this study aimed to investigate drivers’ response and acceptance to the CAVs technology provided through V2I and V2V communications during a hurricane evacuation. A driving simulator experiment was designed (including two scenarios) and seventy-nine drivers from different age groups drove those scenarios. The first scenario was a base scenario with no warnings while the second scenario included three V2I warning messages and one V2V warning message. The V2I messages included rain warning, congestion warning and alternate route information whereas the V2V message was a warning regarding a potential rear end crash with the vehicle at front. The warnings were provided through both in-vehicle display and audio messages. The results indicated that around 90% drivers complied with V2I rain warning, V2V potential crash warning and V2I alternate route information whereas less than 50% drivers complied with the V2I congestion warning. It was found also that the rain warning resulted in lower average speed during rain, the congestion warning resulted in higher time-to-collision (TTC), and the V2V crash warning resulted in higher TTC compared to the situation where no warnings were provided, indicating safe traffic operation during the evacuation time. When providing an advisory through in-vehicle display and audio messages about an alternate route (with shortest path) that can be used during evacuation to avoid traffic congestion on the main road, it was found that 74 drivers (out of 79 drivers) took the alternate route while only 23 drivers did the same in the presence of dynamic message sign (DMS) only. After participating in the experiment more than 80% of the drivers reported that the provided V2I and V2V messages were extremely useful or useful. The insights gained from this research can help in the design and implementation of connected vehicle technologies to improve transportation systems' performance during critical events like hurricane evacuation.</span> </p>

<p>Coastal and river valley communities have become increasingly vulnerable to sea-level rise and other disasters which can disrupt transportation systems. Therefore, it is important for these systems to be resilient. Analyzing the resilience of transportation systems is important for practitioners and decision-makers to identify weaknesses within the network and analyze design alternatives that can improve resilience. Even though research has been conducted in the area of resilience, integrating this concept into everyday transportation practices to prepare for disasters and other disruptions (e.g. inclement weather, traffic incidents, road blockages) remains a challenge.</p>
<p>The goal of this research was to advance the state-of-the-art in transportation activities to integrate resilience into traffic analyses to assist coastal and river valley communities in their resilience practices.</p>

<p>The purpose of this project is to enhance outreach efforts for middle and high school student groups for freight career awareness by using truck driving simulators. While many STEM outreach programs and college curricula centered on transportation topics focus on the careers of engineers and planners, the roles of front-line workforce of our freight systems (drivers, pilots, and operators) are rarely highlighted. Yet, students may better connect with the impacts of engineering and planning work by witnessing how transportation projects impact front-line workers like truck drivers. Moreover, the trucking industry reports workforce shortages as a top critical issue on annual industry reports. Workforce development, for engineers and planners as well as drivers and pilots (for waterway navigation), is a critical issue that can be addressed in part through specialized outreach initiatives. This project developed an outreach program designed around the popularity and use of driving simulators to enhance outreach efforts for middle and high school student groups for freight career awareness. Many universities and, more recently, public libraries and workforce centers, allow public access to driving simulators. To this effect, more than twenty-five middle school girls through the University of Arkansas sponsored summer camp called, GirlTREC, participated in our driving simulator outreach program. GirlTREC is sponsored by the Maritime Transportation Research and Education Center (MarTREC) which is a US Department of Transportation Tier 1 University Transportation Center.</p>
<p>This work shares the lesson plans and lessons learned in engaging middle school students in driving simulator-based activities. This can be a challenging age for introducing transportation topics and driving simulators, as students are not drivers themselves and typically are unaware of transportation system functions. The central goals of the lesson plans are for students to be able to list transportation careers, identify transportation system challenges, and describe the benefits of transportation systems for everyday life. Active learning approaches included in the lesson plans include brainstorming transportation industry careers and reasons for the current shortage of truck drivers, operating four driving simulators including a truck, forklift, excavator, and car. Despite the difficulty in completing some driving tasks on the simulator, e.g., size and scale of equipment relative to student physiques and lack of knowledge on vehicle operations, the girls noted increased awareness of freight careers as well as an appreciation for the transportation industry. Ultimately, this developed outreach module can be used by any university and/or workforce center equipped with a driving simulator to organize their own outreach events.</p>

<p><span>The Covid-19 pandemic wrought unparalleled disruptions in global supply chains and port operations, unleashing congestion, delays, and container shortages of unprecedented magnitude. As governments worldwide implemented containment measures, shaping social behavior and curtailing economic activity, the repercussions reverberated across ports in the United States. These vital hubs encountered formidable challenges stemming from shifts in demand, labor shortages, and supply chain bottlenecks. Compounding these issues, the surge in e-commerce and disruptive events, such as the Suez Canal blockage, intensified pressures on U.S. ports. The pandemic's impact not only exacerbated existing challenges for ports and supply chains but also triggered inflationary pressures.</span></p>
<p><span>This research zeroes in on the profound impact of Covid-19 on port congestion and the global supply chain, with a specific focus on major U.S. ports such as the Port of Long Beach, Port of New York and New Jersey, alongside global counterparts like the Port of Rotterdam and Port of Shanghai. The objectives encompass quantifying shipping volume, identifying trends, analyzing factors, and deepening comprehension for policymakers and stakeholders, crucial in fortifying resilient supply chains.</span></p>
<p><span>In the context of U.S. ports, severe congestion emerges as a consequence of heightened consumer spending and an unprecedented surge in container throughput, overwhelming these crucial gateways. The limited workforce availability during Covid-19 outbreaks exacerbates the challenges faced. In stark contrast, the Port of Rotterdam and Port of Shanghai exhibit consistent vessel dwell times, underscoring their efficiency and resilience. The research underscores the vulnerability of U.S. ports to fluctuations in consumer spending, resulting in an inundation of goods and overburdened ports that compromise efficiency and escalate dwell times. Looking ahead, opportunities for improvement involve addressing existing limitations, enhancing data collection methodologies, conducting comparative studies, and exploring technological innovations. These measures are pivotal in constructing more resilient and efficient global supply chains, particularly for U.S. ports, to navigate the uncertainties and challenges posed by future disruptions.</span> </p>

<p>To cap greenhouse gas emissions, the International Maritime Organization (IMO) has introduced the Energy Efficiency Design Index (EEDI). This index is a measurement of the amount of carbon dioxide that a ship emits in relation to its cargo capacity and speed. The weather conditions affect the emissions. The effect is quantified with a factor (fw) that could affect EEDI by up to around 40%. For seagoing vessels, a significant portion of the weather factor is due to added resistance in waves. This paper includes a unique new technology aiming to reverse the adverse weather effect by converting the wave-induced ship motions directly into a forward ship motion. The technology relies on reaction forces that normally exist when water flows through a pipe bend. An open to the sea ship compartment can be designed to function as a pipe bend. The seawater oscillates inside a specially shaped moon pool due to the relative ship motions in waves. The curved profile of the moon pool deflects the water backward from its natural vertical flow, and the water inertia pushes the vessel forward, according to the momentum conservation law. The new wave-energy drive (WE-Drive) does not have any moving or protruding outside the hull parts. It can efficiently counteract the added resistance in waves. The WE-Drive can reduce the carbon footprint of marine vessels and increase the operability range of battery-powered ships.</p>

<p>This research focuses on a study area in Fort Lauderdale--a two-block stretch of Las Olas Blvd. between Southeast 9th Ave. and Southeast 11th Ave. where researchers expect mean high tides up to 36 inches higher in the year 2100. The project investigates a community planning process in which a combination of high- and low-tech visualization methods—a Geographic Information System (GIS) and a human artist—was used to increase public participation and draw out local knowledge which helps the decision-making process for the future. Mixed reality technologies such as Microsoft Hololens (augmented reality) and Samsung VR Gear (virtual reality) offer immersive educational and engagement experiences, which may convey information in a more meaningful way. Using a quasi-experimental methodology of before-and-after surveys, we compare the degree to which virtual reality technologies improve<br>
(or impede) constituents’ absorption of information regarding sea-level rise risks to roadway infrastructure in their communities.</p>

<p>Recent headlines depict significant shifts in operations within the freight community in particular, e.g., HOS laws suspended at a national level for the first time in 82 years1; national carriers shifting operations completely to grocery supply chains2; fleet operators laying off employees in response to manufacturing closures3. As a result of the current COVID-19 pandemic, there is a great need to capture freight movement data (not otherwise collected) to measure the effects of the COVID-19 response and recovery practices on freight network resiliency. In this project, we consider an expanded definition of the freight network, beyond roads and warehouses, to include truck drivers and driver support systems. </p>
<p>Driver support systems include physical infrastructure like public and private rest stops as well as operational protections like Hours of Service (HOS). COVID-19 responses by public agencies and private citizens have affected drivers and driver support systems by three mechanisms. First, increased demand for medical supplies, food and packaged goods creates a need for more trucks and drivers, and the increased need for quick shipments promotes an environment in which speeding and unsafe driving practices may prevail. Second, with HOS restrictions lifted by the National Highway Transportation Safety Administration (NHTSA) driver fatigue may occur at greater frequency leading to unsafe driving conditions and higher likelihood of accidents. Third, the effects of social distancing mandates can lead to closures of critical, but oft forgotten, freight infrastructure like rest areas and truck stops, leaving drivers without necessary rest opportunities. While any single mechanism has detrimental effects on driver health and safety, the economy, and national recovery efforts, when combined, the system can be pushed to failure. Pandemic responses have only exacerbated critical industry issues like driver shortages, lack of available parking, and HOS compliance issues stemming from electronic logbooks. The purpose of this work was to develop and implement a driver health and safety survey during the pandemic. </p>

<p>The increasing intensity of inland transportation, and in particular road transport, which not only has lead to surging environment pollution but also to significant decrease of motorways capacity in Europe. This has forced us to seek for alternative solutions for transport and communication in Europe.</p>
<p>One of the possible solutions to the above mentioned problem that is currently being investigated by EU organizations is the idea of extending the existing inland waterways toward East. This aims at creating the system of inland waterways (see exhibit 1[1]) that would link the following destination points:</p>
<p>- Baltic and Northern Sea harbors on the North with the Mediterranean and Black Sea harbors on the South,</p>
<p>- Gdansk Bay Area with the system of European inland harbors,</p>
<p>- System of European inland harbors with the existing waterway systems of Belarus, Ukraine and Russia.</p>
<p>Development of transport system using the connections between inland waterways is an alternative to automotive communication.</p>
<p>Introducing new types of inland and coastal ships that are technically advanced environmentally friendly – including modern technical solution of pro-ecological components and systems, to decrease the level of harmful emissions and amount of waste – additionally increases attractiveness of this type of communication, which – apart from the economy values – also has significant ecological virtues.</p>
<p>Moreover, moving car transport onto waterway routes shall relieve the burden on land roads in international scale, increasing their flow capacity and driving safety and decreasing the level of atmospheric contamination and noxiousness of noise in areas directly adjacent to them.</p>
<p>Development of water transport, both commodity and tourist, requires creating of stage stoppage bases and river embankments. The bases are necessary due to the necessity of ship media intake, handing over waste and used materials for disposal, making small repairs and food provision.</p>
<p>Location of these bases is conditioned by maximum distance that a ship can make without technical stoppage, by location of the existing port infrastructure or by optimum conditions for its building and by cultural and landscape criteria that are important in the light of attractiveness to tourists.</p>
<p>Social aspect of construction of this type of base, in particular one that expects to accommodate a certain number of tourists and to organize their attractive stay, is the creation of additional jobs for the local people at the organization and servicing of the necessary hotel and recreation background that can be used by tourists after tourist season.</p>
<p>Presenting local tourism and sightseeing attractions, directing attention in particular to nature monuments, scenic parks, objects of material culture together with their history – is a presentation of cultural heritage of the given region, and the care for its preservation is one of the elements of sustainable development – such as taking into account environmental costs at the construction and exploitation of the stage base.</p>

<p>Coastal and river valley communities have become increasingly vulnerable to sea-level rise and other disasters which can disrupt transportation systems. Therefore, it is important for these systems to be resilient. Analyzing the resilience of transportation systems is important for practitioners and decision-makers to identify weaknesses within the network and analyze design alternatives that can improve resilience. Even though research has been conducted in the area of resilience, integrating this concept into everyday transportation practices to prepare for disasters and other disruptions (e.g. inclement weather, traffic incidents, road blockages) remains a challenge.</p>
<p>The goal of this research was to advance the state-of-the-art in transportation activities to integrate resilience into traffic analyses to assist coastal and river valley communities in their resilience practices.</p>

<p>Ports play a vital role in the economy of nations and provide a critical link in the supply chain. Ports form the gateway by which essential goods are received within large geographic regions. Because of their function, ports are exposed to a substantial risk of flooding, storm events, sea-level rise, and climate change. The resiliency of ports is essential for the economy, the people, and national readiness. The contribution of this research work is in providing a methodology to quantify port resiliency that is applicable at the individual port level and regionally. The research approach first defines a quantifiable measure of systematic resiliency. Then applies this measure to quantify the resiliency of six ports located in the Southeast US impacted by Hurricane Matthew (2016). The details are presented in the final report. Also, the data set used for the report is included.</p>

<p>As part of previous efforts, Texas A&M Transportation Institute (TTI) has developed a methodology relating truck-vessel activity. In subsequent work, TTI enhanced the original methodology by analyzing terminal capacity and operations to identify possible causes related to port activities that influence roadway behavior of trucks. This past work used statistical analyses that delivered quantitative relations in the form of coefficients that could be translated into truck traffic for the surrounding roads of a given port.</p>
<p>This project built on these past studies to develop a supply chain-oriented methodology to analyze performance of the port-related multimodal freight infrastructure. Specifically, the project team identified and matched up the key freight corridors with ship activity to analyze what happens on relevant supply chain corridors at times of ship arrivals and departures. Fluidity measures focused primarily on travel time behavior. The Port of Beaumont, Texas, was used as a case study.</p>

<p>This project developed a quantitative model of the local and regional road and rail network that serves a port, and the flow of goods to and from the port. Port Freeport, Texas was used as a case study. The goal of the project was to develop a reusable quantitative framework to assess questions relating to the port-road transportation system. The goal and objectives were achieved by developing a spatially and temporarily explicit model of routes and travel times between Port Freeport and local and regional (i.e., statewide) commodity sources/destinations. The model was used to evaluate the port-ground transportation resilience questions in line with recent Army Corps of Engineers guidance on assessing resilience (“Maritime Transportation System Resilience Assessment Guide”). Specifically, this was achieved by perturbing the base model to simulate disturbances such as changes in ground transport operations (e.g., road closures, policy) or changes in port operations. In line with the goal of the project, the research team documented the challenges and resources required to develop the model and provided a commentary on the utility of the framework for evaluating the resilience of other port-ground transportation systems.</p>

<p>The U.S. multimodal transportation network is extensively used to transport agricultural inputs and outputs. Disruptions to the transportation network can therefore cause severe and cascading operational and economic damage to the food and agriculture sector. These disruptions are magnified due to the food and agriculture sector's interdependency with other critical infrastructure sectors, dependence on time-sensitive operations, and positioning within rural communities. <br>
<br>
This research investigates (i) how multimodal transportation should be used when a disruption has occurred and (ii) how to coordinate restoration activities across interdependent transportation and agriculture systems. We present a mixed integer linear programming model that seeks to maximize the expected yield for a set of rice farms throughout the state of Arkansas under scenarios where the amount and timeliness of fertilizer delivery are affected by a disrupted transportation network. We validate the model using real data for a case study in Arkansas. This dataset includes the location and acreage of rice farms in Arkansas, fertilizer demand, and a multimodal transportation network comprised of road, rail, and waterway networks. For this dataset, we created disruption scenarios for different transportation modes with different severity, location, and duration. Using these data, we ran extensive computational experiments to deduce operational and restoration insights on the interdependence and resiliency of transportation and agriculture systems. The findings demonstrate the need for coordination, systems thinking, and understanding of how transportation impacts other interdependent infrastructures. Additionally, the model may help to establish a methodology for planning in the agricultural sector.</p>

<p>This interdisciplinary program includes concepts and tools from transportation engineering, computer science, coding, and data analytics through a variety of hands-on opportunities. The Build Kit contains components to build a mini-inductive loop detector from off-the-shelf, low-cost components. The mini-inductive loop (12 in. or less in diameter) connects to a detector card that translates the inductive signal from the loop to an open-source software. The software is used to change loop settings like sensitivity, and to view and download loop readings. The inductive loop can measure the metallic components of a vehicle and is used to classify trucks and cars which have different metal chassis and body configurations.For this project, the lesson plans describe how to build a loop and use it to determine the different types of trucks coming in and out of an inland waterway port. Each lesson plan presents a scenario in which a critical transportation decision can be guided by knowledge of truck and commodity characteristics. </p>

<p>The goal of this project was to attract K-12 students to transportation engineering careers through STEM outreach programs. To accomplish this goal, the object of the project was to design and implement maritime freight oriented educational outreach activities centered on traffic sensing technologies for middle, high school, and first-year college students. In MarTREC Project 5011 (Evaluating the Performance of Intermodal Connectors), the research team designed a low-cost, easily implementable LiDAR and Bluetooth sensor bundle that was capable of detecting, characterizing, and tracking freight trucks as they traveled to and from inland waterway port areas. The sensor provided data necessary to measure port performance and roadway usage by industry. This project re-designed the sensor bundle as an educational outreach activity by creating sensor "build kits" and associated lesson plans for middle school, high school, and first year university students. These build kits were intentionally designed to be scalable and interdisciplinary programs that introduce maritime topics to students ranging from middle school up to college freshman engineering students. The outreach program is scalable in the sense that various parts of it can be included or excluded/re-invented given parameters such as program length or access to technology. This interdisciplinary program includes concepts and tools from transportation engineering, computer science, coding, and data analytics through a variety of hands-on opportunities. </p>
<p>The Build Kit contains components to build a mini-inductive loop detector from off-the-shelf, low-cost components. The mini-inductive loop (12 in. or less in diameter) connects to a detector card that translates the inductive signal from the loop to an open-source software. The software is used to change loop settings like sensitivity, and to view and download loop readings. The inductive loop can measure the metallic components of a vehicle and is used to classify trucks and cars which have different metal chassis and body configurations. Each lesson plan presents a scenario in which a critical transportation decision can be guided by knowledge of truck and commodity characteristics. </p>

<p><span>Mass evacuations, especially at the statewide level, present formidable challenges in traffic management, often characterized by extensive delays and congestion. This paper introduces an innovative analytical method designed for the cost-effective measurement and comprehensive description of such large-scale evacuations. By utilizing straightforward and widely available traffic count datasets, the research delves into critical aspects of evacuation scenarios, addressing key questions pertaining to events like Hurricane Irma and Michael in Florida, as well as Tubbs and Thomas Fire evacuations in California. The analytical approach enables the estimation of the onset and conclusion of auto-based evacuations, understanding loading and peaking traffic characteristics, and determining the total number of vehicles involved in the evacuation process. Additionally, it delineates the effective start and end of the auto-based reentry phase.</span> </p>
<p><span>Building upon prior efforts to quantify evacuation impacts, this research is unique in its dual investigation of hurricane evacuations in Florida and wildfire evacuations in California. By encompassing these distinct scenarios, the study offers valuable insights that contribute to a more comprehensive understanding of the complexities involved in large-scale evacuations. The findings not only enhance our preparedness and response strategies for future events but also provide a versatile framework that can be adapted by state departments of transportation and emergency management officials for diverse evacuation scenarios.</span> </p>

<p>The purpose of this project is to guide strategic investment into port capacity through the development of a policy and infrastructure evaluation model of inland waterway commodity flows. A multi-stage stochastic optimization model will be developed to evaluate tradeoffs in strategic, long-term port infrastructure investment with mid-term capacity expansion decisions and provision of complementary highway infrastructure made by public and private stakeholders, and shorter-term operational practices made by shippers and carriers. This work builds on prior MarTREC projects which developed a Multi-Commodity Assignment Problem to estimate annual commodity flows through inland waterway ports from truck Global Positioning System (GPS), marine Automatic Identification System (AIS), and the Lock Performance Management System (LPMS). The proposed project will explore critical extensions of the assignment model: 1) disaggregation of the temporal scope to reflect monthly seasonality among commodities, 2) incorporation of uncertainty related to observed vehicle and vessel movement data, and 3) inclusion of transportation costs. With these extensions the team expects to increase the accuracy and resolution of the commodity-based port throughput estimates and to allow the model to be used to not only describe the current system but to prescribe policy and project investment strategies for public and private sector transportation decision makers. Calibration and validation of the multi-stage optimization model will be done through two case studies. The regional-based study will use historical truck GPS, marine AIS, and LPMS datasets. The national-based study will use data from the Billion Ton Study led by the US Department of Energy. This will ensure a feasible and realistic base-case on which to compare future policy scenarios. This project aligns with MarTREC’s research focus area in Maritime and Multimodal Logistics Management by modeling commodity flows through ports that serve as critical connections for the multimodal freight supply chain.</p>

<p>The University of New Orleans Transportation Institute (UNOTI) examined the issues surrounding the current state of international chassis utilization in the United States (U.S.). The international chassis system in the U.S. is unique compared to global chassis utilization where the motor carriers, the freight customers, or off-site terminals provide chassis. However in the U.S., the divestment of international chassis by ocean carriers, which began in 2009, resulted in three major international chassis leasing companies linked to the foreign carriers. These lessors are the American shippers’ predominant provider of international chassis. The extra cost associated with the lack of international chassis lessor competition profits the foreign ocean carrier lines while raising costs for domestic consumers.</p>

<p>The existence of Yazoo clay soil in Mississippi frequently causes distress to the pavement and cause deformation at the slopes in highways and levees, which are a critical component in Maritime and multimodal transportation infrastructure. Each year, fixing the pavement requires a significant maintenance budget of MDOT. Also, the infiltration of the rainwater in the highway and levee slopes leads to landslides, which require millions of maintenance dollars each year. Due to the shrinkage and swelling behavior of the Yazoo clay, the hydraulic conductivity varies over the different seasons and has higher vertical permeability during the dry season. With high vertical permeability, the rainwater can easily percolate in the pavement subgrade and slopes, which accelerates the failure. The current study investigates the change in unsaturated vertical and horizontal permeability and its effect on the maritime and multimodal infrastructures, especially on the pavement and slopes of highway embankment and levees. The attached datasets include the laboratory test and finite element modeling findings.</p>

<p>Data set used for the report, "Large Scale Evaluation of Erosion Resistance of Biocementation against Bridge Scour and Roadway Shoulder Erosion". The purpose of the report was to develop an alternative approach for armoring the riverbed with biocementation through MICP to mitigate soil erosion. Long-term erosion exposed to outdoor environment, rainfall induced erosion, and accelerated erosion were conducted on MICP-treated samples to prove the feasibility of the MICP technique for potential applications in prevention of bridge scour and road shoulder erosion. The experimental work and discussion about the testing results indicated that exposing to outdoor environment could result in sharp decrease on UCS for MICP-treated samples. But the MICP-treated samples had better resistance to rainfall induced erosion. The bio-surface treatment gave significant help for cement-treated samples to resist accelerated erosion and water absorption, especially the multiple bio-surface treatments method, no erosion could be measured and 5% lower water absorption was achieved after the cement-treated sample was triple treated by bio-surface treatments. The pure MICP-treated samples were also good at resisting accelerated erosion and water absorption. Furthermore, fiber addition and multiple MICP treatments could improve their resistance. The maximum erosion rate of single MICP-treated samples reduced from 0.16 mm/min to 0 mm/min after triple MICP treatment cycles applied on the samples. Extra MICP treatments on soil samples improved the resistance to water absorption significantly. The triple MICP-treated samples achieved a 6% lower absorption than single-treated samples. All these results indicated that the bio-mediated particulate material based on MICP can provide an effective solution for problematic cases of sandy soil in prevention of bridge scour and road shoulder erosion.</p>

<p>Many maritime structures (e.g., locks, dams, ports) in the US are either reaching or are past their design lives, and there are limited funds for necessary maintenance activities which can often lead to closures. These structures are not easy to detour and often require dewatering before repairs can be made. Closures can cause delays and business-related losses which can have a large economic effect. Thus, it is advantageous to reduce the repair time for maritime structures. BCSA (belitic calcium sulfoaluminate) cement is a promising repair material due to its properties. BCSA cement is a fast-setting hydraulic cement capable of reaching compressive strengths greater than 4000 psi (27.6 MPa) in less than 2 hours. BCSA also has low shrinkage and good long-term strengths. This research consisted of developing an optimal rapid-setting underwater repair mortar mixture design using BCSA cement. Properties such as compressive strength and workability were tested to select the best mix design. Additionally, soil-cements made with BCSA cement were compared to portland cement-based soil-cements. These soil cements have applications for the rapid repair of levees and earthen dams, but also for rapid soil stabilization. The results obtained proved that BCSA cement is a promising material for rapid underwater repairs and repairs of soil-based waterway structures.</p>

<p>Communities are complex systems subject to a variety of hazards that can result in significant disruption to critical functions. Community resilience assessment is gaining popularity as a means to help communities better prepare for, respond to, and recover from disruption. Sustainable resilience, a recently developed concept, requires communities to assess system-wide capability to maintain desired performance levels, while simultaneously evaluating impacts to resilience due to changes in hazards and vulnerability over extended periods of time.</p>
<p>In an earlier work, the authors developed a classification scheme to aid in identification, selection and application of community sustainable resilience indicators that can be tailored to a community’s needs in operationalizing the assessment process. These indicators were characterized according to whether they aligned with social, economic or environmental systems that are necessary for a community to achieve a sustainable resilience domain of survival, well-being, or full preparedness.</p>
<p>Of the critical infrastructure systems that support these systems and domains, transportation is arguably the most important. This is based on the premise that transportation is a means to an end, providing the mobility that enables a community to establish and maintain a social, economic and environmental fabric. Whether it involves an educational, medical, recreational, religious, work or other purpose, absent a safe and reliable transportation system, none of these activities can be satisfactorily pursued. Moreover, in times of crisis, transportation serves as a vital artery for enabling access to and egress from impacted areas.</p>
<p>The objective of this project was to establish and demonstrate a method for evaluating a community’s transportation resilience, such that if deficiencies exist, attention can be focused on mitigating those concerns. This approach was designed around the scenario of a river valley community exposed to the threat of a significant flood event, with the expectation that the methodology has the potential to be extended to assess community resilience to other natural and manmade hazards.</p>

<p>The continued growth of Liquefied Natural Gas (LNG) production and long-distance trade has traditionally been taken as a given by global energy analysts, who have premised their positive estimates on gas being both relatively scarce and demand for it virtually unquenchable. Unfortunately, current conditions in the global energy market suggest that what many have predicted as a near perpetual increase in the volume of traded LNG is in fact a bubble that is now in the process of bursting. This report represents the efforts by the University of New Orleans Transportation Institute (UNOTI) beginning in 2014 to assist the Port of New Orleans (PONO) in evaluating the feasibility and best practices of equipping the PONO for potential storage and shore-side infrastructure for fueling vessels powered by LNG, as well as research into the feasibility of the widespread use of LNG as marine fuel, considering the new United Nation’s International Maritime Organization’s (IMO) MARPOL Annex VI maritime emissions regulations set to take effect in 2020. Additionally, this report examines both the short and long-term factors behind this new thinking about LNG, explore what it implies for the several multi-billion-dollar export projects being built in Louisiana, and the feasibility of LNG as a US export commodity and industrial feedstock to the petrochemical industry. This report concludes by suggesting that development policy aiming to assist LNG export projects are likely misplaced, and that a primary focus on value-added petrochemical manufacturing, with a secondary value as potential for a marine fuel, is a more robust path for the region’s policymakers to take.</p>

<p>In 2011, we observed how “graceful failure” through planned destruction of portions of the Birds Point Levee by the US Army Corps of Engineers (USACE) was enacted to alleviate extreme flooding on the Mississippi River. This action, while flooding thousands of acres of croplands as intended, reduced flooding and potential damage to waterway infrastructure and populated communities downstream. Recent trends and future climatic projections indicate that we will have more of these “extreme” flooding situations in our future. Therefore, this project focused on exploring the potential feasibility to utilize other locations along the inland waterway system where “graceful failure” or planned breach of levees may be used as a means of flood protection for downstream communities and infrastructure. Spatial analysis techniques were used with development of specific criteria to screen national-level data sets to identify probable locations for such mitigative approaches. The criteria were primarily focused on identifying non-urbanized, non-developed land where intentional flooding for storage of flood waters would minimize impacts. Each location that was identified as a potential candidate was further evaluated for capacity for flood water detention. A consolidated set of areas were identified that could provide some storage capacity for flood mitigation. Additional engineering and localized analysis would be necessary to vet the areas for actual storage implementation. However, this study provides an example of an unconventional approach to flood mitigation on inland waterways which could reduce the need for disaster response and assist in transportation planning during extreme flood conditions.</p>
