城市轨道交通多交路共线运营客流分配方法

多交路共线运营客流分配是城市轨道交通复杂交路设计、列车开行方案优化的基础。本 文以典型共线运营多交路为例，通过划分客流出行区段将乘客分为不同类型，分析了不同类型客 流的路径选择策略，提出以发车频率确定的客流分担比例计算方法，构建了基于发车频率和乘客 出行区段划分的客流分配模型。在此基础上，将多交路共线运营物理网络转化为共线运营服务 网络，通过引入超路径的概念，将乘客出行优化策略转化为共线运营服务网络上的最短超路径问 题，并考虑乘客在车拥挤感知费用，提出了基于超路径的客流增量分配方法。最后，通过算例验 证了共线客流分配方法的有效性，对比分析了两种方法的特点和适用性。

Passenger Flow Assignment Method for Common-line Operation with Multi-routing of Urban Rail Transit

The passenger flow assignment for common-line operation mode with multi-routing is the basis of complex routing design and train plan optimization of urban rail transit. Taking the typical common-line operation with multirouting as an example, this paper analyzes the passenger trip routing and develops a passenger flow assignment model. In the analysis, the passengers are classified into different types based on the passenger trip space distributions. The path choice optimal strategies are then analyzed for different types of the passengers. The paper also proposes the calculation methods of passengers' share ratios based on the frequencies of multiple routings, and presents the frequency-based passenger assignment method. The multi-routing common-line physical network is transformed into a common-line service network. By introducing the concept of hyperpath, this paper converts the optimal strategy problem into the shortest hyperpath problem in the common-line operation service network. The passenger flow incremental assignment method is also proposed with consideration of the passengers' perception cost of crowding. The case study verifies the effectiveness of the passenger flow assignment method, and compares the applicability and property of two passenger flow assignment methods.
