Laura Hamm joined Virginia Tech’s “Curious Conversations” to talk about cycling safety, infrastructure, and the behaviors of both riders and vehicle operators. She explained the challenges to getting accurate information about bicycle-vehicle collisions and what conditions make riding safer. She also talked about a project she’s working on that will help the Virginia Department of Transportation better assess traffic stress, connectivity, and accessibility of bike and pedestrian routes and her own experience as an avid cyclist. Hamm is a senior research associate in the Division of Vehicle, Driver, and System Safety at the Virginia Tech Transportation Institute. Her research focuses on the safety and mobility of vulnerable road users, including cyclists and pedestrians. She is currently leading a pilot program to collect and analyze naturalistic data from cyclists aimed to better understand bicycle-vehicle interactions and cyclist behavior under diverse environmental contexts. She is also leading a project in Virginia to incorporate new data sources into the calculation of level of traffic stress for pedestrians and cyclists.
