摘要
随着城市轨道交通的不断发展,快慢车运输组织模式逐渐成为提升旅客出行效率、实现快速直达服务的重要策略。目前越行站的位置与数量设定多依赖于运行图铺画过程,工作效率及分析精度相对较低。为解决该问题,文章从越行产生的场景出发,提出快车与慢车初始发车间隔、慢车之间的初始发车间隔,以及越行站工程代价是影响越行站位置的主要因素,并据此总结制定越行站设置规则,设计基于发车间隔关系动态枚举的越行站位置和数量的求解算法。通过构建验证案例求解得到9种可行方案,验证理论方法的有效性和实用性,对解决城市轨道交通工程的越行站设置问题具有重要的指导意义。
With the continuous development of urban rail transit,the transportation organization mode of express/slow trains has gradually become an important strategy to enhance the travel efficiency of passengers and realize the fast and direct service.However,at present,the location and number of overtaking stations are mostly dependent on the process of drawing the operation diagram,and the working efficiency and analyzing accuracy are relatively low.To solve this issue,the article starts from the scenario in which overtaking stemmed from,proposes that the initial departure interval between express and slow trains,the initial departure interval between slow trains,and the engineering cost of overtaking stations are the main factors affecting the location of overtaking stations,and summarizes the rules for setting overtaking stations accordingly,and designs the algorithm for solving the location and number of overtaking stations based on the dynamic enumeration of the relationship of the departure intervals.Nine feasible solutions are obtained through the construction of validation cases to verify the validity and practicability of the theoretical method,which is of great significance in solving the problem of overtaking station setup in the urban rail transit project.
