设计并实现了一种基于无线传感器网络的智能交通系统。利用布设在道路两端的无线磁阻传感器节点,实时检测车流量,并将该信息传输至汇聚节点与后台管理中心,根据车流量优化道路红绿灯变换循环。实验结果表明:系统对车辆的识别率较高,且在一定程度上提升了道路行车效率。
An intelligent transportation system based on wireless sensor networks is designed and realized.Wireless magnetoresistive sensor nodes are deployed at both sides of road to realtime monitor traffic flow and send this information to Sink node and backstage management center.The conversion cycle about the red and green lights is optimized according to the traffic flow.Experimental results show that recognition rate on vehicles is high and efficiency of road traffic is enhanced to a certain extent.
