摘要
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.
