A Review of Evidence-Based Traffic Engineering Measures Designed to Reduce Pedestrian-Motor Vehicle Crashes

This review uses the Transportation Research Information Services database to identify studies on engineering to reduce speed, separate pedestrians from vehicles, and increase visibility of pedestrians.

  • Single-lane roundabouts, sidewalks, exclusive pedestrian signal phasing, pedestrian refuge islands, and increased intensity of roadway lighting yield the most effective increase in pedestrian safety.
  • Results report that modifications of the built environment can substantially reduce the risk of pedestrian-vehicle crashes.
  • More research is needed in the field of traffic engineering measures and effects on pedestrian safety.
