摘要
换乘设施规划布局对枢纽换乘效率至关重要。利用系统动力学的理论及方法,从系统性角度研究枢纽设施与交通需求匹配关系,确定构建枢纽内部换乘系统运能匹配系统动力学模型的一般方法。运用该方法构建枢纽内部铁路换乘城市轨道交通运能匹配模型。以北京西站铁路换乘地铁系统相关数据进行实例验证,发现安检设施为铁路换乘地铁系统的运营瓶颈点,经验证发现模型误差在3%以内。针对系统运营瓶颈点提出相应改善措施,运用该模型进行仿真发现,适当增加安检机、扶梯、楼梯以及检票机的数量,能够很大程度上提升系统客流运营的效率。
The transfer facility planning is important for the efficiency of public transit terminals. Based on the relationship between facilities of public transit terminals and travel demand, this paper presents the techniques for capacity matching of transfer system in public transit terminals using system dynamics method. A model of capacity matching railway-rail transit transfer system in terminal is developed. Taking relevant data of railway-subway transfer system at Beijing West Railway Station to demonstrate model application, the result show that safety inspection facilities are the operation bottleneck while the error of the model is within 3%. The paper proposes measures to improve the operation bottleneck. The simulation results show that the moderate increase in the number of safety inspection machine, escalator, staircase, and ticket checking machine can substantially enhance the efficiency of passenger flow operation of the system.
