摘　　要：作为中心城市和卫星城之间的纽带,市域快速轨道交通的高效运输组织有助于降低运营成本、提高旅客出行效率。开行快慢车已成为市域快速轨道交通运输组织的主要方式。研究越行站设置方法和模型,明确不同条件下越行站设置规律可更好地满足运营需求。根据运行图结构推理,从理论上形成了判断越行发生的条件和越行站位置的计算方法,建立越行站设置规则,设计基于选择规则的启发式算法实现越行站位置的自动计算。在此基础上通过调整参数分析该方法的灵敏性,总结了越行站、通过能力、发车间隔以及快慢车开行数量比之间的关系。基于多项式假设,对分析结果进行拟合,形成计算越行站个数、第1越行站位置以及越行站设置间隔函数关系,均达到比较高的精度。As the connection between central cities and satellite cities,the efficient transportation organization of urban rapid rail transit can reduce operating costs and improve passenger travel efficiency.The operation of express and local trains has become the main method of urban rapid rail transportation organization.Studying the method and model of setting up overtaking stations and analyzing the law of setting overtaking stations under different conditions can better meet operational needs and provide support for route planning and design.Based on the timetable,this paper theoretically established the conditions for judging the occurrence of overtaking and the calculation method for overtaking station positions,summarized the rules for setting up the overtaking stations,and developed a rule-based heuristic algorithm to realize the automatic calculation of the overtaking station positions.On this basis,the sensitivity of the proposed method was analyzed by adjusting the parameters,and the relationship between the overtaking station,the passing capacity,the departure interval,and the ratio of the number of express and regional trains was summarized.Based on the polynomial assumption,the sensitivity analysis results were fitted to form a functional relationship to calculate the number of the overtaking stations,the first overtaking station location and the overtaking station setting interval,with relatively high accuracy.
