Transportation demand modelers are challenged by the new mobility options available to travelers. These options include shared mobility services, automated vehicles, and micromobility technologies. Modeling may be done for the near term (when evaluating new services) and longer term (when preparing transportation improvement plans) and the longer term projections are particularly difficult. NCHRP Report 896, Updating Regional Transportation Planning and Modeling Tools to Address Impacts of Connected and Automated Vehicles, and AMPO’s National Framework for Regional Vehicle Connectivity and Automation Planning describe new approaches for planning that consider uncertainty and agencies could benefit from knowing how these approaches are being applied. A topic of particular interest is the proclivity of travelers to share rides with strangers.




The objective of this research is to identify the key transportation demand modeling parameters related to traveler use of the new mobility options, review and summarize traveler behavior studies that could inform selection of those parameters (including factors that positively or negatively affect traveler acceptance), and recommend approaches to track and project changes in traveler acceptance of these mobility options.
