复杂交路条件下的城市轨道交通客流分配研究

城市轨道交通客流分配的关键在于确定乘客的换乘方案，而乘客的换乘不仅受线网的影响，还受到各条线路运行交路的影响。以分析复杂运行交路对旅客换乘影响为基础，阐述根据轨道交通线网和运行交路构建乘客换乘网络的方法，利用该网络可直观地表达乘客的换乘情况，且网络中不含节点费用，方便了客流分配相关量的计算。在分析换乘网络弧的阻抗计算方法的基础上，建立城市轨道交通客流平衡分配模型，并对模型进行简要分析，最后通过实例求解，检验该客流分配方法的有效性。

Passenger Flow Distribution for Urban Rail Transit Considering Complex Routing

The key problem of passenger flow assignment for urban rail transit is to determine the transfer scheme. But the transfer scheme is not only affected by the network but also by the routing mode of railway. Therefore, the impact of the complex routing is analyzed at first. Then, the construction methods of transfer network for urban rail transit are proposed. The network can visually express passenger transfer paths. And it is easier to calculate the relevant costs of traffic flow distribution without node cost. Based on the analysis of the calculation method of network arc impedance, the model of equilibrium passenger flow distribution is established and analyzed. Finally, the effectiveness of the method is illustrated by numerous experiments on instances.
