Safer Roadways: A Complete Streets Guide
Manual (PPM) Chapter Two or AASHTO guidance. The consideration of sight distance should account for the presence of on‐street parking when applicable. Curb Extensions - The construction of curb extensions is recommended at mid-block crosswalks where feasible. Uses for these extensions can include transit stops, micromobility corrals, additional greenscaping, and green stormwater infrastructure. Lighting - When regular street lighting is not present or is inadequate to reach minimum illumination levels, separate crosswalk lighting should be installed. Crossing locations with high nighttime demand should include separate crosswalk lighting, which may include in-street lighting. Frequency of Marked Crosswalks - Along streets with high pedestrian levels in Urban and Suburban contexts, a well ‐ designed crossing should be provided at least every 1/8 mile (660 feet) so the minimum distance to the nearest controlled or protected crossing is 300 feet. Marked crosswalks should be spaced so people can cross at preferred locations. If people are routinely crossing streets at nonpreferred locations, consideration should be given to installing a new crossing. Other Safety Enhancements - For guidance on the use of crosswalk safety enhancements including high-visibility crosswalk markings, raised crosswalks, advanced warning signs, in-street pedestrian crossing signs, curb extensions, pedestrian refuge islands, RRFBs, and pedestrian hybrid beacons, refer to the FHWA Guide for Improving Pedestrian Safety at Uncontrolled Crossing Locations 38 .
