Abstract
Extensive efforts have been made in pedestrian evacuation of urban rail transit systems, since there has emerged an increasing number of congestion problems. However, few studies focus on the comprehensive urban rail transit hubs. As a comprehensive interchange hub integrating urban railway and intercity railway lines, Beijing West Railway Station was taken as a case study object. The pedestrian evacuation characteristics were analysed first. Then, a social force-based simulation model of Beijing West Railway Station was constructed in PTV Viswalk. The model was applied to visually display a real evacuation process and help identify evacuation bottlenecks. The results showed that the risk points at different facilities had various causes and features. Furthermore, the simulation model could also be used to evaluate the effectiveness of different optimization measures as long as certain model parameters were changed beforehand.
Highlights
In the past few decades, more comprehensive rail transportation hubs have been planned and built to improve the pedestrian travel efficiency
The results show that the walking speed of males was generally higher than that of females, which may be attributed to the height difference
The evacuation time consists of three parts: the first is the time of entering the station, that is, the time taken by the pedestrian from the ticket gate to Density
Summary
In the past few decades, more comprehensive rail transportation hubs have been planned and built to improve the pedestrian travel efficiency. Beijing West Railway Station is a typical largescale comprehensive interchange hub, which includes ordinary railway trains and highspeed railway trains, and serves as an interchange station of Beijing Subway Line 7 and Line 9. It was selected as our study object. To analyse the pedestrian evacuation characteristics and help construct the simulation model, a field survey was conducted at the station during the evening peak hours (5 p.m.-7 p.m.) of February 26, 2019 (Tuesday), which is the busiest time period of the station in general during a whole day. The time difference between the two is the pedestrian average transit time through
