Although pedestrian traffic safety remains a major issue, increasing deterioration and maintenance costs of traffic lights to protect safety are also becoming a problem. Recently, geometry improvements of unsignalized crosswalks - particularly the midblock two-stage type - have garnered attention as an effective alternative tool for providing safe crossing opportunities without relying on traffic signals. Some case studies in Japan have shown excellent results in terms of drivers' higher yielding rate and speed reduction. This article summarizes safety and efficiency improvement effects of unsignalized crosswalk facilities with improved geometry, as well as approaches for setting up such facilities in accordance with the road hierarchy. This is done by examining examples in Japan and abroad.
