基于WIFI和蓝牙数据的公交客流OD分析方法研究

Research on OD analysis method of bus passenger flow based on WIFI and Bluetooth data

针对目前大多数研究是基于IC卡数据和GPS数据来获得公交OD信息,对各站点的下客人数推算精度不足,该文提出一种基于WIFI探针和蓝牙数据的方法来获取公交客流OD。在公交站台安装WIFI探针和蓝牙信号检测器来识别公交车辆上的设备,通过对两个数据源的处理与融合,计算得到公交车辆内部的设备数量,并结合公交车辆乘客上车时的IC卡数据,计算出公交车辆的上下客流,利用相关算法来推算基于WIFI和蓝牙的公交客流OD矩阵,根据上下车客流对OD矩阵进行校对,得到更准确的客流信息。

Most studies are based on IC card data and GPS data to obtain bus od information,and the calculation accuracy of the number of passengers is insufficient.This paper proposes a method based on WIFI probe and Bluetooth data to obtain bus passenger OD.WIFI probe and Bluetooth signal detector are installed at the bus stop to identify the equipment on the bus.Through the processing and fusion of the two data sources,the number of equipment in the bus is calculated.Combined with the IC card data of bus passengers getting on the bus,the up and down passenger flow of the bus is calculated,and the relevant algorithm is calculated the OD matrix of bus passenger flow based on WIFI and Bluetooth.The OD matrix is checked according to the boarding and alighting passenger flow to obtain more accurate passenger flow information.
