基于均衡和接续的路网列车运行图调整研究

铁路中的换乘车站如果发生突发事件,会造成路网中部分列车到达换乘站晚点,晚点超出一定范围时与之接续的列车将不再保持接续关系,导致旅客无法完成换乘且接续列车晚点。本文建立了基于均衡和接续的路网列车运行调整模型,调整后使列车到达终点站的时刻与原计划时刻偏差最小并且总延误时间最小。使用Gurobi优化软件对模型进行了求解,结果表明,调整后的运行图能够有效缓解突发事件对列车运行造成的影响,且晚点在一定的范围内,通过列车接续能够保证旅客的顺利换乘。

Equalization and connection based train diagram adjustment for railway network

Some trains would be delayed in arriving at a transfer station if transfer station emergency occurred in railway network. The connection trains would no longer continue maintaining the connection relationship if delay exceeded a certain limit. This would cause passengers not to complete a transfer and connection trains to be delayed, We establish an equalization and connection based model for train operation adjustment, The purpose is to make total delay minimal and the gap between the adjusted arrival time and its original value shortest. We also employ optimization software Gurobi to solve the model. Results show that adjusted train diagram can effectively mitigate the impact of the emergency on train operation network and ensure regular transfer of passengers by train connection if delay is controlled within a certain scope.
