摘要
为了基于路网交通流信息实现动态路径诱导系统,提出通过物联网和公交线路进行路网交通流信息动态采集方案。在各公交站台安装RFID读写器,每辆公交车粘贴RFID电子标签,通过站台子系统采集运营公交车辆到站时间,利用Zig Bee技术将公交车辆、站台系统和交通管理中心连接起来,将运营的公交车辆到达每个站点的时间传递给交通管理中心,交通管理中心根据公交车辆预计到站时间与实际到站时间的延误情况来估计路网交通流,估计出的路网交通流信息可以提供给城市路径诱导系统作为实现动态路径诱导的依据。
In order to implement dynamic router guidance based on road network traffic flow information,the dynamic traffic information gathering scheme according to Internet ol things and bus lines is proposed.In the scheme,RFI D reader is installed at the bus platforms, R FID tag is fixed on the every bus, thearrival time of running bus at every platform is gathered by platform sub system. Bus vehicle,platformsystem and traffic management center are connected by ZigBee technology, the running bus real-timemonitor information is transferred to traffic management center, traffic management center estimate theroad network traffic flow according to the delay between real arrival time and estimated time of the bus,then the road network traffic flow information may be provided to the city route guidance system for theimplementation of dynamic router guidance function.
