摘要: 分析了影响城市轨道交通乘客路径选择的主要影响因素,建立了城市轨道交通路径选择的广义费用函数,并分析乘客在城市轨道交通网络中的路径选择行为。应用Logit模型对城市轨道交通网络的客流分配问题进行了理论建模,通过统计调查数据对模型和算法进行了有效性验证。通过问卷调查数据,采用极大似然估计方法,标定了模型中的参数,在有效路径搜索算法方面,提出了一种基于深度搜索优先和分支界定思想的有效路径搜索算法,以得出符合现实的有效路径集合。最后,在北京市轨道交通网络客流中,运用本文所提出的模型和算法估算了立水桥站到国贸站OD对之间各有效路径被选取的概率,并通过实测调查数据进行了验证,结果表明了本文所提出的模型和算法的有效性。

Abstract: This study focuses on the major factors influencing the passenger flow assignment in the Urban Rail Transit (URT) network. A generalized fare function is modeled for URT. It also takes full consideration of travelers’ route choice behaviors in URT network. A Logit-based model is developed to emulate passenger flow route assignment, and the model is validated by computer simulation. According to the survey results, this study determines the weighting coefficients in the proposed model by the Maximum Likelihood Estimation Algorithm. Moreover, it proposes an effective-path searching method based on Depth Priority Searching and Branch & Bound Algorithm. Taking Beijing URT network as an example, the study estimates the probability of selecting each effective-path between Lishuiqiao station and Guomao station, which is verified by real data. The proposed model and algorithm are proved to be effective.

Key words: urban rail transit, passenger flow, route choice, OD matrix, Logit model
