Abstract:Wireless Sensor Networks(WSNs) is a novel technology of information acquisition and processing，which integrates the technologies of sensor, network, and MEMS. And it can be widely deployed for measurement, detection and monitoring applications. In this paper, combined with traditional information acquisition and processing technologies, a new highway traffic monitoring system based on WSNs is presented. And the configuration, functions and mechanism of the new monitoring system are described.
Keywords: Wireless Sensor Networks, Information acquisition, sensor, Traffic Monitoring System
