基于区域协同的轨道交通发车时刻模型研究

Study on Model of Departure Time of Rail Transit under Regional Collaboration

为实现城市轨道交通换乘时间的最佳衔接和提高轨道交通运营系统的效率，对基于区域协同的轨道交通发车时刻问题进行了研究。在分析轨道交通线网协同性，考虑轨道交通内部线路间的换乘衔接和换乘站到达乘客的特性的基础上，以乘客在换乘站总候车时间最小为优化目标，建立了区域协同的发车时刻线性规划模型。并用两条十字交叉的轨道交通线路的算例验证了模型的可行性和有效性。结果表明该方法能最大限度地减少乘客在换乘站的总候车时间，尤其是对于发车间隔较大的轨道交通线路间的换乘时间节约效果更为明显。

In order to optimize transfer time among lines of urban rail transit and improve the efficiency of urban rail transit operation, this paper studies on the departure time problem of urban rail transit based on regional collaboration. On the basis of analyzing collaboration of urban rail transit network and considering the transfer between lines and characteristics of passengers who arrive at transfer stations, the linear programming model about departure time of regional collaboration, which minimizes the total waiting time of passengers at transfer stations, is established. The feasibility and effectiveness of the model with application examples through two crossed rail lines are validated. The result indicates that this method minimizes the total waiting time of passengers at transfer stations, especially for rail lines with large headways.
