PEDESTRIAN CROSSING-TIME REQUIREMENTS AT INTERSECTIONS

Existing procedures for determining pedestrian crosswalk-time requirements are inadequate because they ignore the number of people crossing. A study of six crossing locations showed that those in large crossing groups walk at fairly uniform headways and uniform speeds. Pedestrian headways are close to 6.7 sec per pedestrian per foot width of walkway and speeds are close to 4.5 ft/sec. A model of crossing time is developed. The inputs are the number crossing, crosswalk length, and crosswalk width.
