摘　　要：轨道交通系统中运营收益与乘客车厢空间感知度是一种对立关系,通过研究该两因素对轨道发车间隔进行优化,能够实现合理收益范围内提升乘客车厢空间感知。考虑列车上下行两方向影响以及乘客候车时间、供需平衡、最大载客量、配备车辆数,列车运行安全间隔等方面的约束,建立发车间隔优化模型,采用遗传算法求解多变量非线性优化问题,得到不同子时间段的优化方案。应用模型对武汉市轨道交通4号线高峰期间不同时段优化计算,发现轨道发车间隔调整后,运营收益小幅度下降能够有效提升车厢空间感知度;并通过客流敏感性分析,研究客流量按一定幅度提升下轨道运营收益与乘客车厢空间感知度的变化规律,可为城轨列车运营决策提供参考。The operation income and the passenger compartment space perception of the rail transit system is an opposite relationship.Through the study of these two factors to optimize the departure interval of rail transit,the passenger compartment space perception could be improved within a reasonable income range.Considering the influence of the train’s upstream and downstream direction and the constraint of factors such as passenger waiting time,supply and demand balance,maximum passenger capacity,number of vehicles equipped and the safety interval of train operation,the departure interval optimization model was established,and the genetic algorithm was used to solve the multi-variable nonlinear optimization problem.The optimization schemes of different sub-periods were obtained.The proposed method was applied to optimize and calculate Wuhan Rail Transit Line 4 during different periods of peak hours.It is found that after the adjustment of the transit departure interval,the small decrease of operation income can effectively improve the passenger compartment space perception.Through passenger flow sensitivity analysis,the change law of rail operation income and passenger compartment space perception under the condition of passenger flow increasing to a certain extent is studied,which can provide reference for the decision-making of urban rail train operation.
