Abstract :
This paper designs a wireless sensor network for road traffic information acquisition. Geomagnetic sensors of traffic state acquisition are also designed. The geomagnetic sensor can be adaptive to the surrounding changes about magnetic field and magnetic interference. Besides, it can possess traffic flow, speed and occupancy detection simultaneously and synchronously. For the research and development of wireless sensor, we will focus on the vehicle recognition and reducing energy consumption.
