基于客流特征分析的西安地铁2号线行车组织优化措施

Traffic Organization Optimization of Xi'an Metro Line 2 Based on Passenger Flow Characteristics Analysis

以西安地铁十字换乘的两条线路运营现状为背景,重点分析了地铁2号线断面客流的时空分布特征和运能运量匹配情况;提出了目前2号线存在高峰(尤其早高峰)时段运能不足、上下行不均衡程度大、换乘站客流压力大等问题。根据客流特征分析,从错开北大街列车到站时间、加开备用车、上下行不均衡运输组织、开行大小交路等方面,提出了行车组织优化措施,为西安地铁2号线下阶段行车组织提供参考。

Taking the operation status of Xi’an metro lines as the background,the temporal-spatial distribution characteristics of the section passenger flow and the transport capacity matching of metro Line 2 are selectively analyzed. The existing problems on metro Line 2,such as the shortage of transport capacity especially in the morning rush hours,the lager uplink and downlink imbalance degree,and the higher passenger flow pressure at transfer stations are discussed. According to the characteristics of passenger flow,the optimization of traffic organization measures is proposed,including staggering the train arrival times at the North Street Station,starting the standby trains,traffic organization for uplink and downlink imbalance,operation for the full & part routes,in order to provide a reference for the next phase of traffic organization on metro Line 2.
