基于换乘协调的城市轨道交通列车开行方案优化

The Optimization of Urban Rail Transit Operation Scheme based on Coordinated Transfer

针对目前我国城市轨道交通列车开行方案对于线路之间的换乘协调问题考虑较少存在的问题,结合城市轨道交通旅客换乘的特点,构建换乘机理模型,并以车站换乘旅客平均等待时间最短作为目标函数,设计优化模型对列车开行方案进行优化。通过算例分析,说明优化效果较为明显,对于地铁等城市轨道交通运营有一定的参考价值。

Aiming at insufficient consideration on the coordination transfer between lines in the operation scheme of urban rail transit trains in China, combining with the passenger transfer characteristics of urban rail transit, the transfer mechanism model was established. Taking shortest average waiting time by transfer passengers in station as the object function, the optimization model was designed to optimize train operation scheme. Through analyzing examples, the optimization effect was proved obvious, and has reference value on urban rail transit operation like metro.
