【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。
[Abstract]:The layout of transfer facilities is very important to the transfer efficiency of the hub. Using the theory and method of system dynamics, this paper studies the relationship between hub facilities and traffic demand from a systematic point of view. The general method of constructing the dynamic model of the transport energy matching system of the internal transfer system of the hub is determined. By using this method, the matching model of the transportation capacity of the railway transfer to the urban rail transit within the hub is constructed. The railway transfer system of the Beijing West Railway Station is used to transfer to the subway system. The relevant data are verified by an example. It is found that the security inspection facility is the operating bottleneck point of railway transfer subway system, and the model error is found to be less than 3%. The corresponding improvement measures are put forward for the bottleneck point of the system operation, and the simulation results are carried out by using the model. Properly increasing the number of security machines, escalators, staircases and ticketing machines can greatly improve the efficiency of system passenger flow operation.

【正文快照】： 当前,随着交通需求日益增加,综合客运枢纽承担的换乘客流也逐渐增大;在客流高峰期,综合客运枢纽内部存在部分换乘设施通行能力严重不足、而部分换乘设施通行能力远大于客流需求的现象。换乘设施通行能力不足会造成客流拥挤排队,不仅严重影响综合客运枢纽的换乘效率,甚至容易诱
