高峰时段城际铁路列车停站方案研究

为缓解高峰客流拥堵,提高列车服务能力,通过对各种运行列车组在沿途中间站的停站组合分析,推导出始发站列车发车间隔的计算公式。以此为基础,构建以站间服务可达性、列车到达时间、旅客候车时间等作为主要约束条件,旅客旅行时间消耗最小化为目标的非线性0-1规划模型,同步优化城际铁路客流高峰时段的列车停站方案与运行图。根据模型特点设计遗传算法对算例进行求解,验证设计的模型及算法可行,能够为制定城际铁路列车停站方案提供参考。

Study of Train Stop Scheme for Inter-city Railway during Peak Hours

In order to alleviate the congestion of passenger flow during peak hours and improve the train service capacity, the calculation formula of the train departure interval at the originating station is derived through analyzing the stop combination of various train groups at the intermediate station along the route. Furthermore, a 0-1 nonlinear programming model is constructed with the main constraints of inter-station service accessibility, train arriving time and passenger waiting time, with the objective of minimizing the travel time. Meanwhile, the train stop scheme and operation diagram for inter-city railway during peak hours are optimized. According to the characteristics of the model, a genetic algorithm is designed to solve the problem, and the feasibility of the model and algorithm is verified, which can provide reference for formulating of train stop scheme for intercity railway.
