城市轨道交通客流时空分布特性研究

利用城轨自动售票系统(AFC)数据分析西安地铁1、2、3号线客流,得到不同类型车站客流特征,将典型车站不同时间的站间OD可视化处理,通过映射方式对OD矩阵时空分布情况进行可视化。结果表明:(1)由于西安是一个旅游城市,工作日只有早、晚高峰时段客流高于节假日,其他时段客流低于节假日;(2)早、晚高峰出行具有明显潮汐特性,早高峰高客流发生点为居住区,客流吸引点为办公、商业区,晚高峰与之相反;(3)高客流走廊依次为(商业→混合)>(居住→商业)>(商业→居住)>(商业→商业)>(混合→商业)>(交通→商业)>(商业→交通)>(办公、工业→商业)>(商业→办公、工业)>(居住→办公、工业);乘客出行目的依次为工作、回家、购物、其他类出行。

Study on Spatial-Temporal Distribution Characteristics of Passenger Flow in Urban Rail Transit

The passenger flow data of Xi'an Metro Lines 1,2 and 3 were analyzed based on AFC data to generate the passenger flow characteristics of different types of stations.The OD of typical stations at different times was visualized,and the spatial-temporal distribution of OD matrix was visualized by mapping.The results show that:(1)As Xi'an is a tourist city,the passenger flow in the morning and evening peaks of workdays is higher than that in holidays,while the passenger flow in other periods or the full-day passenger flow is lower than that in holidays;(2)The trips in the morning and evening peaks present obvious tidal characteristics:the high passenger flow in the morning peak comes from residential zones,and the destinations are office and commercial zones,while the evening peak is on the contrary;(3)The corridors with high passenger flow are(commercial→mixed)>(residential→commercial)>(commercial→residential)>(commercial→commercial)>(mixed→commercial)>(traffic→commercial)>(commercial→traffic)>(office and industrial→commercial)>(commercial→office and industrial)>(residential→office and industrial),and the trip purposes of passengers are work,home,shopping,other trips.
