Effects of Road Collisions on the Travel Behavior of Vulnerable Groups:Expert Interview Findings

We interviewed eight subject-matter experts in California in 2023 tounderstand how travel behavior and priorities may change in response to direct experience with road collisions. Expertsrepresented a variety of perspectives, including medical doctors, advocates for active transportation safety, and advocates for people with disabilities. Their diverse specialties enabled us to capture a variety of concerns without triggering emotionally sensitive areas for people who have directly experienced road collisions. These experts identified common themes, including mental stress from the prospect of returning to driving—especially on freeways, lesser incidence of long-term changes in travel modes after experiencing a collision, dependence on others for rides in private vehicles, and changing routes or times of day of travel when traveling independently. These experts also explained how people’s mode choices are also affected by general concerns about collisions in the news more than by specific personal experiences with near misses. Interview subjects’ spoke of more specific concerns as well. These included but were not limited to, bicyclists using sidewalks instead of bike lanes when both are present, feeling stigmatized from using public transit or paratransit after experiencing a collision, and concerns with motorists treating bicyclists badly. These initial interviewsclarify areas of focus and methodology for future qualitative and quantitative studies on the intersection oftransportation safety and travel behavior change, particularly as they involve people who have directly experienced road collisions.
