摘要
研究目的:在利用既有铁路资源发展市域(郊)铁路的背景下,本文研究旨在提高市域(郊)铁路的运营效率,以满足乘客的出行需求。通过分析不同到达模式下的乘客行为,提出一种适应混合到达模式的市域(郊)客流分配方式。基于“线路国有、国铁与地方共营”管理模式,构建一个多目标优化模型,综合考虑乘客出行时间、运营成本和地方政府成本,并采用遗传粒子群优化算法求解,优化列车开行方案。研究结论:(1)通过对某条市域(郊)铁路线路早高峰时段客流数据的实证分析表明,构建的市域(郊)列车开行方案优化模型能够显著提高运营效率;(2)该模型早高峰时段缩短了乘客总旅行时间34.8%,降低了铁路局运营成本10.2%,减少地方政府成本11.5%,并节省了10%的车辆购置费用;(3)本研究成果可为利用既有铁路开行市域(郊)列车的项目规划决策和运营优化提供参考。
Research purposes:Against the backdrop of utilizing existing railway resources for the development of suburban(commuter)railways,this study aims to improve the operational efficiency of suburban railways to meet passenger travel demands.By analyzing passenger behavior under different arrival patterns,a traffic allocation method for suburban railways under a mixed arrival pattern is proposed.Based on the"national ownership of lines,comanagement by national and local railways"model,a multi-objective optimization model is constructed,which comprehensively considers passenger travel time,operational costs,and local government costs.The model is solved using a genetic particle swarm optimization algorithm to optimize train scheduling plans.Research conclusions:(1)Empirical analysis of peak morning passenger flow data from a suburban railway line shows that the constructed optimization model for suburban railway scheduling can significantly improve operational efficiency.(2)The model shortens total passenger travel time by 34.8%during peak morning hours,reduces railway operational costs by 10.2%,decreases local government costs by 11.5%,and saves 10%on vehicle acquisition costs.(3)The results of this study can be applied to project planning decisions and operational optimization for suburban railways utilizing existing railway resources.
