IPTEM V 2.8

Combining information from Public Transport Providers, the National Travel Survey and the Irish Car Stock Model, a comprehensive picture of passenger transport demand for Ireland is developed. The novel Irish Passenger Transport Emissions and Mobility (IPTEM) Model calculates the passenger transport demand by trip mode, purpose and distance over the period of 2009 – 2019. Historical data from public transport providers in Ireland and a technological car stock model for Ireland can highlight the different energy and emissions intensities used to service travel demand in Ireland. Improvements in efficiencies, changing occupancy rates and fossil fuel switching can be detected in this model using its data from 2009 to 2019. Estimates of transport mode occupancy are also made. The data in this paper highlights the overarching trends in energy consumption patterns in passenger transport over the period of 2009 – 2019 and provides a basis for deeper analysis of the role of transport demand reduction and modal shift to reduce passenger transport emissions.

The peer-reviewed paper complimenting this open-source model is available here.

Included in this repository is the latest version of the Irish Passenger Transport Emissions and Mobility (IPTEM) Model V 2.8, current updates to the IPTEM model are ongoing.
