SN-UTIA: A sensor network for urban traffic information acquisition

An architecture of sensor network for urban traffic information acquisition is proposed. The hybrid communication modes include CAN, ZigBee and Ethernet, which can satisfy the requirements of wired and wireless, real-time and massive data transmission. The various kinds of nodes and the prototype sensor network were developed and deployed in Beijing. The test results show the architecture, hybrid communication mode, various sensor nodes and the sensor network proposed in the paper are practical and feasible. This kind of sensor network can be used in traffic surveillance to resolve the problems of present information acquisition.
