A review of evidence-based traffic engineering measures designed to reduce pedestrian-motor vehicle crashes

The authors provide a brief critical review and assessment of engineering modifications to the built environment that can reduce the risk of pedestrian injuries. In this review, they used the Transportation Research Information Services database to conduct a search for studies on engineering countermeasures documented in the scientific literature. They classified countermeasures into 3 categories- speed control, separation of pedestrians from vehicles, and measures that increase the visibility and conspicuity of pedestrians. They determined the measures and settings with the greatest potential for crash prevention. Their review, which emphasized inclusion of studies with adequate methodological designs, showed that modification of the built environment can substantially reduce the risk of pedestrian-vehicle crashes.
