City of Philadelphia SMART Grant Digital Right-of-Way and Mobility Improvement Project Dataset

Through the Digital Right-of-Way (ROW) and Mobility Improvement Project, the City of Philadelphia developed and implemented a set of new technologies to test digital management of the right-of-way (ROW). Traditionally, as in other cities, Philadelphia issues regulations on how roadways and sidewalks may be used or blocked, and posts physical signs that users must read, interpret, and follow to use the street safely and legally. The Smart Cities team, in partnership with the Streets Department, Open Mobility Foundation, and several vendors, tested communicating these right-of-way regulations and closures digitally, such that a user’s phone or vehicle could receive them, parse out relevant information for specific location/day/time and turn it into guidance for the user - for instance, should the user park or not, and if a user is blocking a bike lane or not.

One of the most important deliverables for the project was the development of the Right-of-Way Data Specification (ROWDS), a formal way to standardize and structure City ROW rules for computers to use, and its implementation through Road Rules, a software product by the company INRIX. These technologies have helped increase the spatial resolution (the level of detail for mapping small areas) of the underlying basemap to match what the Streets Department needs to operate. The project also demonstrated that higher spatial resolution can help the city better manage street-closure permitting. As this project is operationalized through a citywide deployment, it will pave the way for an improved user experience for everyone who uses the roads and a more efficient permitting system for the City of Philadelphia.
