换乘枢纽中流线交叉对换乘效率的影响分析——以西安站北广场扩建项目为例

Analysis on the Influence of Streamline Crossing on Interchange Efficiency in Transfer Hubs——A Case of North Square Expansion Project of Xi’an Station

交通换乘枢纽在城市建设中有着重要的作用,而客流换乘效率在评价换乘枢纽设计方案的优劣时,具有重要作用。本文以西安站北广场扩建项目为例,以三种换乘空间组织模式的方案为研究对象,通过控制变量法弱化换乘距离的影响,将三种方案中的流线交叉作为重要影响指标。通过客流模拟量化比较,得出各方案换乘效率的高低比较结果,从而得出立体多厅式换乘效率最高,以及流线交叉多的方案换乘效率不一定低的结论。

Transfer hub is of great significance to the city, thus its interchange efficiency is a vital factor in evaluating the design plan of transfer hub. This paper takes the north square expansion project of Xi’an station as an example, studies three schemes of transfer spatial organization modes, weakens the influence of interchange distance by controlling the variables and takes the streamline crossing in three schemes as important influencing indexes. By comparing and simulating the passenger flow, the transfer efficiency of each scheme is obtained. It is concluded that the transfer efficiency of the vertical multi-level hall is the highest and the transfer efficiency of the scheme with more streamline crossing is not necessarily low.
