Coordinated Passenger Flow Control and Bus Connection Setting during Peak Hour of Urban Rail Transit

In order to alleviate urban rail traffic congestion during peak hour and balance the percentage of stranded passengers in different stations, this paper proposed a multi-station passenger flow control model for the rail transit station. The model takes maximum interval transport capacity and shortest passenger delay time as objectives, and takes the passenger flow demand, train capacity, interval passage capacity, and platform capacity as constraints, to solve optimal passenger flow control stations, control time, and control intensity. In order to reduce passenger overflow caused by the passenger control in rail transit station, an evaluation method of the bus connecting is proposed from the perspective of connecting travel time and passenger demand. Taking passenger flow data in the morning rush hour of Nanjing Metro line 1 as an object, the collaborative control of passenger flow in multiple stations and the analysis of bus connecting routes were conducted. The results show that passenger flow control can effectively improve utilization rates of passenger flow in each section, balance passenger retention in each station, and put forward a new idea of multi-mode public transport coordination for the improvement of passenger travel satisfaction.
