高铁站高架送客通道交通运行效率分析

Analysis on Traffic Operation Efficiency of Elevated Passenger Entrance Passage at High-Speed Railway Station

以南昌西高铁站高架送客通道设计及管理为例,通过收集进站机动车流量、车辆到达及通过时间等数据,对现有高架送客通道的3种不同设置形式的交通运行效率进行了对比,分析所存在的问题,并提出改进设计思路,结合排队模型进行改进方案效果评估。提出在停车车道明确施化停车泊位,保障行车车道畅通,同时考虑行人安全通道设计,相比较只是单纯地进行进站区车道划分的情况,具有更好的运行效率。

Taking the design and management of the elevated passenger entrance passage of Nanchang West High-Speed Railway Station as an example, this paper compares and analyzes the traffic efficiency of three different passageways of the present elevated passenger passage by collecting the data of the flow, arrival and passing time of vehicles etc. Based on present problems analysis, the paper proposes the idea of improving the design, and evaluates the effectiveness of the improved scheme using the queuing model. The paper puts forward that the improved scheme with the parking space set explicitly in the parking lanes, the driving lanes not affected by parking,and the pedestrian safe passage considered, has better operating efficiency than the situation of simply dividing lanes on elevated entrance platform.
