- Abstract:
- In order to find a method which can describe the passenger flow dynamical distribution of urban mass transit during interval interrupted operation, an urban railway network topology model was built based on the travel path dual graph by considering interchange, crowd and congestion. The breadth first valid travel path search algorithm is proposed, and the multipath passenger flow distribution logit model is improved. According to the characteristics of passengers under the interruption condition, the distribution rules of different types of passenger flow are proposed. The method of calculating the aggregation number of station is proposed for the case of insufficient transport capacity. Finally, the passenger flow of Beijing urban mass transit is simulated for the case study. The results show that the relative error of most of transfer passenger flow is below 10%. The proposed model and algorithm can accurately assign the daily passenger flow, which provides a theoretical basis for urban mass transit emergency management and decision.
- 为了较为准确地对城市轨道交通在运营中断等特殊条件下的客流动态分配及其影响进行分析计算,在综合考虑换乘、拥挤、等待等因素基础上构建了基于出行路径对偶图的阻抗模型.采用了基于广度优先的有效路径搜索算法,构建了改进的Logit模型.根据中断条件下乘客的出行特点,给出了不同类别客流的分配规则,并提出了中断运力不足情况下站内聚集人数计算方法.最后,以北京城市轨道交通某日客流量为例进行实验.结果表明,大部分换乘方向的相对误差值在10%左右.该模型与算法能够较为准确地对日常客流量进行分配,为城市轨道交通应急管理及决策支持提供了理论依据.
