摘要：	There has been an increased emphasis on improving pedestrian safety. The desire to improve pedestrian safety extends to areas typically seen as being non-pedestrian-friendly, such as the higher speeds and wider roadways.With traffic conditions changing as traffic volumes and congestion increase, pedestrians ability to safely cross many roadways is affected. Recent developments in geometric design features, traffic control devices, and technologies may improve pedestrian safety and access by addressing specific problems associated with roadway crossings. Although numerous treatments exist at unsignalized crossings, there is growing concern about their effectiveness. Thus, there is a need to identify and study selected treatments to determine their effectiveness. A recent research project jointly sponsored by TCRP and NCHRP was initiated to address this particular need. The research was conducted by the Texas Transportation Institute (TTI). The study had two main objectives: (1) to recommend selected engineering treatments to improve safety for pedestrians crossing high-volume, high-speed roadways at unsignalized intersections, in particular those served by public transportation; and (2) to recommend modifications to the Manual on Uniform Traffic Control Devices for Streets and Highways (MUTCD) pedestrian traffic signal warrant.
