abstract="We provide a brief critical review and assessment  of engineering modifications to the built environment that can reduce the risk  of pedestrian injuries. In our review, we used the Transportation Research  Information Services database to conduct a search for studies on engineering  countermeasures documented in the scientific literature. We classified  countermeasures into 3 categories-speed control, separation of pedestrians from  vehicles, and measures that increase the visibility and conspicuity of  pedestrians. We determined the measures and settings with the greatest potential  for crash prevention. Our 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.",
