In this project, both stated and measured data will be used to evaluate the San Joaquin Valley's carsharing program, volunteer ride-hailing program, and the "mobility-as-a-service" smartphone application.
This project will address limitations in the current literature surrounding air quality impacts of vehicle traffic, especially in underserved communities. The team will employ a refined near-roadway emission exposure surrogate that balances spatial precision and computational burden to estimate changes in exposure levels and health risks and the distribution of these burdens over time as EV adoption increases.
The project will examine how air-based freight services can be integrated into intermodal freight networks to support more resilient, efficient supply chains, particularly during disruptions.
This project will develop an Accessibility Criticality Index for Vermont's statewide roadway network and evaluate it against the existing mobility-oriented Network Criticality Index used in Vermont's Transportation Resilience Planning Tool.
This project will assess and document methods used to determine Unlinked Passenger Trips and Passenger Miles Traveled at transit agencies across California, including sources of potential error such as fare evasion.
This project will develop a tool to evaluate the costs and benefits of active transportation projects as a part of Caltrans Active Transportation Program project evaluation.
This project examines the uncertainties of on-demand ride-hailing, and policies that transportation planners are implementing to curb negative effects.
