摘　　要：城市轨道交通行车组织多样化背景下,多交路共线运行模式逐渐得到规划者与运营者的青睐。然而,普遍采用的均匀发车间隔时刻表难以解决恒定运力供给与时变客流需求间的矛盾,也未发挥出多交路共线运行模式的优势。为提升城市轨道交通服务水平,本文分析时刻表优化的关键因素,利用分时段客流OD数据,调整列车到发间隔,构建多交路共线运行线路的时刻表优化模型,并采用CPLEX求解。算例研究中,选取两层交路的城市轨道交通Y型线进行优化,满载率大于0.6的运行区间数量及满载率均衡性分别优化96.8%和41.4%,验证了模型的有效性。Under the background of diversified operation organization of urban rail transit,the operation mode of shared-path route is favored by planners and operators.However,it is difficult to solve the contradiction between the constant capacity supply and the time-varying passenger flow demand by the commonly used timetable with uniform departure interval,and it does not give full play to the advantages of the sharedpath route.In order to improve the service level of urban rail transit,this paper analyzes the key factors of timetable optimization,uses the OD data of passenger flow to adjust the arrival and departure interval of trains,constructs the timetable optimization model of shared-path rail transit route,and uses CPLEX to solve the problem.In the case study,the two-tier urban rail transit Y-shaped line is selected for optimization,and the number of sections with full load rate greater than 0.6 and the balance of full load rate are optimized by 96.8%and 41.4%respectively,which verifies the effectiveness of the model.
