Three-axis magnetoresistive sensor based on Anisotropic Magnetoresistive Technology(AMR) has excellent performance on detecting traffic Information. Data results for some features of microscopic magnetic field changes were obtained for road traffic after designing the test equipment of three-axis magnetic sensor and some experiments on road vehicles. The rules between the feature of microscopic magnetic field changes on road traffic and the impact by vehicles are found to realize the traffic Information detector for providing accurate data for intelligent transportation systems(ITS).
