Pedestrian bridge design affects the behavior of the pedestrian,including the passing time,the passing flow,probability of pedestrian violation,etc.Based on the field investigation of two different types of pedestrian bridge,this paper analyzes the influence which the design of pedestrian bridge exerts on the pedestrian traffic.This paper also analyzes how the design of pedestrian bridge influences passing time,passing flow,probability of pedestrian violation and provides an important reference for pedestrian bridge designing.
