Role: PI; Amount: $19,476

This project investigates travel decisions undertaken by commuters across the Commonwealth of Pennsylvania by scanning through Penn State's commuting population across all the campuses. In addition to understanding their travel mode choice and descriptive commuting characteristics, this study will investigate travel mode dissonance among Penn State commuters and its contributing factors. The study will also explore commuting satisfaction and the impact of this trip on subjective well-being.

This project investigated the change in commuting trends (specifically on commute mode choice) across the United States of America through the lens of various geographic and demographic spheres. Results show that commute mode choice trends vastly vary across the country, and accurate determination of triggers/factors influencing commute mode choice is necessary for serving as inputs into planning and policymaking.

This project investigated the impact of COVID-19 on activity participation, trip making, and travel behavior using a nationwide stated preference survey that was disseminated by the PI. Analysis of the survey revealed the multitude of ways in which COVID-19 had impacted travel behavior, including residential location, vehicle purchase, telecommuting, trip making, and activity participation. Results also revealed how consumer preferences would alter regarding the use of shared mobility systems, considering the threat posed by the global health pandemic.

This project created a roadmap for incorporating ACES technologies into Florida DOT’s planning and policymaking efforts in the area of transformational technologies. Central to this project was creating a GIS-based database and activity viewer to serve as the storehouse of all ACES-related projects and efforts across the state. The activity viewer could serve as the foundation for knowledge and technology transfer, and the data, when made available, could be used by all stakeholders, including the public, to understand the state’s efforts in incorporating ACES technologies into our transportation system.

This project investigated the impact of two events – Hurricane Irma and Woolsey Fire on the transportation network performance in Florida and California. Large-scale evacuation data triggered by these two events were collected, and roadway performance metrics created by the project team were used to characterize the performance of the roadway network. Investigations revealed several insights on roadway utilization, bottlenecking in otherwise normal conditions, and the impact of a no-notice event (such as a wildfire) on evacuation patterns that were quite different from those triggered by a short-notice event such as a hurricane. The results from this effort serve as key lessons for state agencies at the forefront of disaster planning and evacuation management.
