摘　　要：城市轨道交通网络因其普遍采用一票换乘制,导致网络客流分布状态的获知成为黑箱难题,而动态客流分配是获取客流在线分布状态的关键技术。本文提出一种基于时空网络的动态客流分配方法,首先对城轨交通网络进行简化,并构建乘客出行的时空网络;进而构建乘客时空路径选择的Logit模型,并对网络客流进行分配;最后以国内某城市轨道交通网络为例,采用真实AFC客流数据进行客流分配。结果表明,采用本文方法计算得到的分配结果与换乘站客流感知系统的一致性达到88.55%,且可满足线网客流在线监测的需求。本文所提出的动态客流分配方法准确、高效,可为城轨交通运营提供实时客流的数据支撑。The one-ticket transfer system commonly adopted in urban rail transit networks makes the passenger flow distribution state a black box that is difficult to be known.Dynamic passenger flow allocation(DPFA)is a key technology to obtain the distribution state of in-line passenger flow.This study proposes a DPFA method based on spatio-temporal network.Firstly,simplify the urban rail transportation network and construct the spatio-temporal network of passenger travel;then,construct the Logit model of passenger spatio-temporal path selection and allocate the network passenger flow;finally,take the urban rail transportation network of a city as an example,and use the real AFC passenger flow data to allocate.The results show that the consistency between the allocation results calculated by the method in this study and the passenger perception system reaches 88.55%,and it can meet the demand of real-time passenger flow monitoring.The DPFA method proposed in this paper is accurate and efficient,and can provide real-time passenger flow data support for urban rail transit operations.
