Abstract
Quantifying the effects of crosswalk length and signal timing on pedestrian walking speed is an important requirement for providing a rational safety assessment at signalized intersections. This study investigates the effects of pedestrian green time (PG), crosswalk length and pedestrian crossing direction on pedestrian walking speed at signalized crosswalk. It is assumed that the pedestrian walking speeds consist of two components v1 and v2 at two consecutive halves of crosswalk. Empirical analysis shows that the longer crosswalk tends to induce the higher walking speed. Pedestrian walking speed increases as PG proceeds. Furthermore, a comparison of pedestrian speed models for PG and PF (pedestrian flashing green time) demonstrates that pedestrian walking speeds at PF are higher and more variable than at PG. The sensitivity analysis helps understand how these models behave depending on change of each variable.
