Active transportation investments play a key role in improving mobility, safety, and sustainability across California. However, estimating their full benefits remains a challenge, particularly when relying on limited or non-local data. In this research webinar, Dr. Dillon Fitch-Polse and Caitlyn Linehan presented their work applying and evaluating the framework of the California Active Transportation Benefit-Cost Tool with infrastructure projects in Santa Barbara and Santa Cruz, California. Their research incorporates local data, expands model training datasets, and compares two approaches to estimating active transportation volume change, the key estimate underlying social benefit calculations. The findings provide insights to help agencies better understand estimates of project and program cost-effectiveness, including impacts on mode shift, emissions, safety, and physical activity.

Dr. Dillon Fitch-Polse
Co-Director, BicyclingPlus
Dillon Fitch-Polse studies travel behavior and transportation planning and teaches in the Transportation Technology and Policy Graduate Group and the Department of Environmental Science and Policy at UC Davis. Through field experiments, travel surveys, and crowdsourced data, Dillon’s recent research has focused on how road environments influence people’s bicycling attitudes and behavior. His current work explores the role of bike shares and other micromobility services in changing travel behavior. He also develops tools to improve planning for bicycles and emerging small vehicles.
Caitlyn Linehan
PhD Student, Geography Department, UC Santa Barbara
Caitlyn Linehan's research focuses on utilizing spatial sciences to study walkability and green space access in urban areas, as well as equity of that access.
