Abstract

Abstract: This paper conducts a set of field measurements to obtain data of decision-making behavior and crossing speed of pedestrians at an intersection without traffic lights in downtown Wuzhou, Guangxi. The concepts of decision-making distance and critical safety distance are introduced through analysis and fitting of statistical data. The observed data show that pedestrians’ crossing speed at off-peak hour fluctuates around the mean speed and does not perfectly obey the normal distribution based on the D’Agostino test. The mean speed at off-peak hour is only 0.6 m/s when the waiting time is counted, whereas it is 0.8 m/s without considering the waiting time.

Key words: crossing speed, decision-making behavior, pedestrian flow, traffic flow
