| Abstract: | 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. |
