备注

为适应城市轨道交通网络化运营需求,编制列车行车计划应当尽可能缩短乘客的换乘等待时间,方便乘客出行.从实用性和可操作性出发,提出网络换乘的主动衔接和被动衔接概念,在此基础上利用逐步优化的思路对列车行车计划进行优化,优先针对换乘客流大的换乘方向进行衔接,然后按换乘客流大小依次衔接网络上剩余换乘方向,得到优化后的列车行车计划.以上海市轨道交通网络为例验证算法的计算流程和优化结果.结果表明,在网络衔接中不同线路的列车开行间隔呈现相同或者倍数的关系,网络的整体衔接程度较优.

In order to meet the demand for urban rail transit network operation, train operation planning should shorten the waiting time of passengers as much as possible to facilitate passengers to travel. From the aspect of practicability and operability, this paper puts forward the concepts of active and reactive coordination, on the basis of which, train schedules are optimized step by step. The plan is optimized, and priority is given to the transfer direction with large passenger flow, and then the remaining transfer direction on the network is connected in turn according to the size of the transfer flow. Finally, Shanghai rail transit network is taken as an example to show the validity of the proposed algorithm, as well as the calculation process and optimization results. The case study shows that the overall coordination of metro network is better when the train intervals of different lines are the same or multiple in the network connection.
