基于无线传感器网络的混合型道路快速公交信号优先系统设计与应用

Application of BRT Signal Priority System of the Hybrid Road Based on Wireless Sensor Network

针对混合型道路公交车辆信号控制问题,综合采用微波、RFID,ZigBee和北斗卫星导航系统等多种传感技术构建公交沿线无线传感器网络,实现对交通运行参数监测、BRT车辆准确定位和无线通讯功能,通过车辆设备与信号机间的信息交互,实现了信号的优先控制,提高了公交的运行速度。

Aiming at the signal control of the hybrid road,the authors propose the construction of the wireless sensor networks along the bus route,such as microwave,RFID,ZigBee,BeiDou Navigation Satellite System and other sensor technology,which could help realize the traffic parameters monitoring,the accurate positioning and wireless communication of BRT vehicles.Through the information exchange between the vehicles and signal controllers,the signal control has been prioritized and the efficiency of the bus improved.
