摘要
地铁线路时刻表的协调有利于节省乘客在不同线路之间的换乘时间,对于同站台换乘的情况,除了要考虑乘客换乘时间外,还需要兼顾换乘客流对冲的安全因素.本文首先建立了地铁列车到站时刻协调优化的混合整数线性规划(MILP)模型,模型以乘客总换乘时间及列车惩罚项之和最小为优化目标,包含列车到站时刻、乘客换乘行为以及换乘客流对冲三组约束条件.接着,本文构造了四个数值算例,使之涵盖两条线路发车间隔的三种关系:两者相等;两者不等且成倍数关系;两者不等且不成倍数关系.结果表明,本文模型针对线路发车间隔的三种关系,均能给出最优解,在避免或减少换乘客流对冲的情况下,使得乘客总换乘时间达到最小.
The coordination of metro timetables is beneficial for saving passengers5 transfer time between different lines.When it comes to the actual situation of cross-platform transfer stations,in addition to the transfer time,the safety factor related to conflicts of passengers traveling in opposite directions on the platform should also be considered.This study first established a mixed integer linear programming(MTLP)model for coordinating the arrival time of metro trains.The objective of the model is to minimize the total passenger transfer time and train penalty terms.The model includes three sets of constraints:train arrival time,passenger transfer behavior,and opposing passenger conflicts.After the development of such a model,four numerical examples were designed to cover the three relationships between the departure intervals of two metro lines:equal,unequal and multiplied,and unequal and non-multiplied.The results show that the model can predict an optimal solution for the three relations of train departure intervals.It can minimize the total passenger transfer time while avoiding or reducing the conflicts of passengers traveling in opposite directions.
