Abstract
Pedestrian crossing speed and waiting time are critical parameters for designing traffic signals and ensuring pedestrian safety. This study aimed to carry out microscopic level research on 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 a videography survey method. Descriptive and statistical analyses were carried out, and then two multiple linear regression (MLR) models were developed for these two parameters by using the collected 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 control type, 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 wait more than 20–30 s to cross the road. Furthermore, the waiting time of the pedestrians varied with intersection control type, gender, age, minimum gap, waiting location, and vehicle flow. Findings of this study will help to alleviate traffic safety problems by designing an effective intersection control system.
Highlights
Most of the daily trips are made on foot in Bangladesh, just like many other low-income and developing countries, and a recent study indicated that 42% of trips were made on foot in Dhaka City, the capital city of Bangladesh [1]
Pedestrians who waited at the sidewalk waited a longer time than pedestrians who waited on the road
This study examined the pedestrian crossing speed and waiting time of pedestrians at intersections in Dhaka city
Summary
Most of the daily trips are made on foot in Bangladesh, just like many other low-income and developing countries, and a recent study indicated that 42% of trips were made on foot in Dhaka City, the capital city of Bangladesh [1]. Rahman and Khadem conducted a study on the physical and operational deficiency of signal system of Dhaka. They found that among the 70 signalized intersections, 84% were fixed time (FT) signal systems where the prefixed timing plan in those intersections did not match with the demand of actual flow [4]. Hasan found a similar result in his study He added that the timing deficiency of traffic signals made the pedestrians and road users confused and increased difficulties [5]. Both studies concluded that the signal control system of Dhaka was not working properly
