突发大客流对轨道交通换乘站服务水平和列车运行影响分析

Impact of Emergent Large Passenger Flow on Service and Train Operation at Transfer Station

换乘站作为城市轨道交通网络的重要节点,其连通性和可靠性对客流出行特征有着重要影响。在分析不同换乘方式对网络客流分配影响的基础上,以城市轨道交通路网发生突发大客流为例,以站台候车区的乘客密度、到达列车的剩余载客能力、站台候车乘客数和乘客的上车效率等几个因素为主,研究了当载有突发大客流的列车在换乘站产生到达延误后,对车站服务水平和列车运行的影响,并给出了定量化公式。同时,进一步得出了成网条件下,突发大客流对换乘站的影响机理。

As a key node in urban rail transit network, the connectivity and reliability at transfer station cast impor-tant impact on passenger travel characteristics. On the basis of passenger flow assignment in different transfer modes, the impact mechanism of emergent large passenger flow on service level and train operation at transfer station is ad- dressed, especially when the arrival train is delayed. Sever- al mathematical formulas are put forward, including the passenger density in waiting areas, additional passenger ca- pacity in the arrival train, the number of waiting passen- gers and the passengers＇ riding efficiency as well.
