Analysis of Pedestrian Crossing Speed and Waiting Time at Intersections in Dhaka

摘要

Pedestrian crossing speed and waiting time are critical parameters for designing trafficsignals and ensuring pedestrian safety. This study aimed to carry out microscopic level researchon pedestrian crossing speed and waiting time at intersections in Dhaka. To fulfill this aim,crossing-related data of 560 pedestrians were collected from three intersections in Dhaka using avideography survey method. Descriptive and statistical analyses were carried out, and then twomultiple linear regression (MLR) models were developed for these two parameters by using thecollected data. From the results, 1.15 m/s was found to be the design pedestrian crossing speed.Results also show that the crossing speed of pedestrians was associated with intersection controltype, gender, age, crossing type, crossing group size, compliance behavior with control direction,and crossing location. In case of waiting time, findings show that pedestrians did not want to waitmore than 20–30 s to cross the road. Furthermore, the waiting time of the pedestrians varied withintersection control type, gender, age, minimum gap, waiting location, and vehicle flow. Findingsof this study will help to alleviate traffic safety problems by designing an effective intersectioncontrol system.
