多模式耦合的城际铁路列车开行方案优化方法
Optimization Method of Intercity Train Operation Diagram Based on Multi-mode Coupling
【摘要】 随着区域经济一体化和都市圈的快速发展,城际铁路线路运营环境因各制式轨道交通的相互影响而变得更加复杂,进而对列车开行方案的编制提出更高要求。从城际铁路的视角出发,探究多模式耦合交通系统的竞争与协作机制。在竞争层面,采用多项Logit模型评估城际铁路对本线客流的吸引力;在协同层面,引入接续时间窗概念,分析城际铁路与干线轨道交通不同接续条件下的换乘过程。在此基础上,考虑客流、车站和区间能力、上座率、列车运行等约束,构建以综合客运周转量和企业效益最大化为目标的非线性整数规划模型,设计模拟退火算法求解。结果表明,多模式耦合的城际铁路列车开行方案优化方法可以提升城际铁路客运分担率至39.57%,提供81.97%的换乘联运服务,显著增强了城际铁路服务效能。
【Abstract】 With the regional economic integration and rapid development of metropolitan area, the operation environment of intercity railway lines becomes more complex due to the mutual influence of various railway systems, which demands higher requirements for the preparation of train operation diagram. From the perspective of intercity railway, this paper explores the competition and cooperation mechanism of multi-mode coupled transportation system. At the competitive level, the multinomial Logit model is used to evaluate the attractiveness of intercity railway to the passenger flow of this line; At the synergy level, the concept of connection time window is introduced to analyze the transfer process between intercity railway and mainline railway under different connection conditions. On this basis, considering the constraints of passenger flow, station and section capacity, occupancy rate, train operation, etc., a nonlinear integer programming model with the goal of maximizing the over passenger turnover and enterprise benefits is constructed, and a simulated annealing algorithm is designed to solve it. The results show that the multi-mode coupling optimization method of intercity railway train operation diagram can improve the share rate of intercity railway passenger transport to 39.57%,provide 81.97% of intermodal transfer service, and thus significantly enhance the service efficiency of intercity railway.
