Abstract:Speed is a contributor to both crash frequency and crash severity. This project explored efforts to reduce speed and evaluated their effectiveness in improving safety for pedestrians and bicyclists. This project included two phases. Phase 1 was a program scan that identified countermeasures in use throughout the United States. Based on findings from the program scan, the project team evaluated automated speed enforcement (ASE) and road conversions in five municipalities to explore their impact on motor vehicle‐related pedestrian and bicyclist crashes. ASE evaluations showed potential for reductions in pedestrian and bicyclist crashes with results limited to one type of deployment in one location. Evaluations of road conversions showed potential reductions in pedestrian and bicyclist injury crashes and mixed results for total injury‐related crashes. Phase 2 of the project evaluated safety benefits of a select group of temporary road conversions implemented in response to the COVID‐19 pandemic. A scan for localities identified locations with temporary installations to create space for pedestrians and bicyclists. This phase included an evaluation that found a crash reduction benefit in the short term and identified quick‐build installations and promising measures to test conversion designs before permanent installations.
