城市轨道交通站台等候区客流时空特性研究

为了探索城市轨道交通站台等候区域乘客密度的时空特性，通过设计站台等待区乘客密度数据采集试验，采用录像交通信息采集方法对西安市轨道交通2#线7个代表性站点的站台等待区晚高峰时间上、下行乘客密度进行采集；在此基础上，利用SPSS数据分析软件对乘客密度的时空特性进行分析与评价。结果表明：西安市北大街换乘站在晚高峰时段站台等待区的乘客密度明显高于其它站，下行方向的站台等待区乘客密度普遍高于上行方向，非工作日的站台等待区乘客密度普遍高于工作日。研究结果进一步丰富了城市轨道交通站台区交通组织与规划的调查方法与基础数据，为站台区域交通设计和安全应急疏散提供了可靠依据。

Study on Spatial and Temporal Characteristics of Passengers in Urban Transit Platform Waiting Area

In order to explore the spatial and temporal characteristics of passenger density in urban transit platform waiting area, data acquisition test of passenger density in platform waiting area is designed, video traffic information collection methods are used to collect the downlink passenger density in platform waiting area during evening peak hours at 7 representative stations in Xi＇an Subway Line 2. On this basis, SPSS is used to analyze and evaluate the spatial and temporal characteristics of passenger density. The results show that the passenger density in platform waiting area of North Street Station is significantly higher than that of other stations during evening peak hours, the passenger density in downstream direction is generally higher than that of upstream direction, the passenger density of non-working day is generally higher than that of workday. The results further enrich the base data and on traffic organization and planning of urban transit platform area, and provide a reliable basis on traffic design and survey methods safety emergency evacuation of platform area.
