20 Pedestrian Refuge Island Source: Federal Highway Administration Crossing Lighting A pedestrian refuge island (i.e., a median) are raised areas that are constructed in the center of the roadway and serve as a place of refuge for people who cross mid-block or at an intersection and shorten the crossing distance. They allow people crossing to concentrate their attention on one direction of traffic at a time and allow users to wait for motorists and find an adequate gap in traffic before crossing the second half of the street. It is a proven safety strategy for reducing crashes per the FHWA with a typical crash reduction of 46 to 54 percent. Average total costs vary. Crosswalk lighting is a strategy that installs streetlights at, and in advance of, intersections and crosswalks to improve visibility and safety of the person crossing. It is a proven safety strategy for reducing crashes per the FHWA with a typical crash reduction of 42 percent. The lux (amount of light in lumens per square meter) is recommended at 20 to 40 lux at five feet above the road surface to provide adequate vertical illumination within a crosswalk. Lighting is particularly important at mid-block crossings and should illuminate the entire crossing form curb ramp to curb ramp as illustrated above. Average cost is $10,000 to $40,000 per intersection. Advanced Stop Bar and Signage Source: National Association of Transportation Officials An advanced stop bar is typically striped 20 feet to 50 feet in advance of a marked crosswalk to encourage drivers to stop further back from the crossing which enhances the comfort for those crossing. The stop bar and corresponding sign also provides the key benefit for multilane roadways of removing the multilane threat by improving the visibility of a crossing pedestrian for motorists.
