The Relationship between Community Design and Crashes Involving Older Drivers and Pedestrians

This study uses negative binomial regression models to understand how urban form may affect total and KSI (killed or seriously injured) crashes involving drivers and pedestrians aged seventy-five and older. Intersections, strip commercial establishments, big box stores, and arterial thoroughfares were associated with increases in crashes involving older motorists, while big box stores and arterials increased crashes for older pedestrians. Networks of lower-speed streets were associated with fewer crashes involving older motorists and pedestrians. This study concludes by detailing community design considerations that may enhance the safety of older motorists and pedestrians
