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.
