地铁与市郊铁路过轨运营下列车开行方案研究

Train Planning for Through Operation between Subway and Suburban Railway

在分析地铁与市郊铁路过轨运营特点的基础上,以乘客节省的总旅行时间最大化和地铁运营企业增加的总费用最小化为目标函数,建立了过轨运营下列车开行方案双目标规划模型,并设计了基于模糊数学规划的求解算法.以某两条轨道交通线路为算例,研究过轨运营开行方案并对相关参数进行灵敏度分析.研究结果表明,地铁与市郊铁路过轨运营既可节省乘客总旅行时间又可增加运营企业收益,且过轨客流需求越大、过轨站换乘时间越长、过轨方缴纳的过轨费用越少、过轨列车运营组织方案越合理,过轨运营效果越显著.

Based on the operation features of the through operation between subway and suburban railway,a train planning model is built under through operation, which is a multi-objective programming model with maximizing the passenger＇s total saving time and minimizing the operator＇s total operating cost. A fuzzy mathematical programming approach is presented to solve the model. Then, a case study is conducted to demonstrate the effectiveness of the model. Furthermore, sensitivity analysis is made to show the influence of the related factors such as the passenger demand, transfer time. The results show that it is timesaver and payoff under through operation. What is more, it is more significant to adopt through operation when the through passengers are larger, the transfer time is longer, the through cost is lower, the train planning of through trains are more reasonable.
