基于仿真的城市轨道交通客流分配

Passenger flow Assignment of Urban Rail Transit Based on Simulation

建立仿真客流分配模型可实现城市轨道交通(URT)客流的分配。首先,定义URT网络并确定了乘客生成方法;其次,结合改进Logit模型及有界理性模型建立乘客出行路径选择模型;接着,基于列车运行图实现列车运行控制及乘客上、下车决策;然后,建立了自反馈机制实现乘客出行路径计算结果的校正;最后,以成都地铁为例,验证了所建立模型的有效性。结果表明:所建立的仿真客流分配模型能够有效实现URT客流的分配,客流分配结果能够为运营部门制定调度指挥策略、乘客制定出行策略提供依据。

The simulation passenger flow assignment model is proposed here to assign Urban Rail Train(URT) passenger flow effectively. Firstly, defining the URT network was defined and the passenger generation method was determined. Secondly, the passenger travel path decision model combing with the improved Logit model and bounded rational model was proposed. Thirdly, the train was controlled by a train diagram and the decision model for passenger boarding and alighting was formulated. Fourthly, the passenger flow assignment result was corrected by the self-feedback mechanism proposed here. Finally, the simulation passenger flow assignment model was verified by Chengdu subway. The results indicate that the simulation passenger flow assignment model proposed here can assign passenger flow effectively and the assignment result is helpful to URT’s dispatch and control, passenger’s travel decision.
