Tóm tắt

Understanding pedestrian platoon dispersion at signalized crosswalk is essential not only for improving pedestrian safety but also for estimating pedestrian crossing time requirement. This paper proposed platoon dispersion ratio (PDR) as an index to analyse the effects pedestrian demand and crosswalk length upon pedestrian platoon dispersion at signalized crosswalk. The result shows that the heavier pedestrian demand usually corresponds to greater platoon dispersion. Regarding the influence of crosswalk length, it is revealed that the dispersion tends to increase as the crosswalk length increases
