  Wireless vehicle detection is a kind of new vehicle detection system which extensively used in urban traffic vehicle management to collect and transmit traffic flows and status on urban roads to front-end signal controllers and center database.
Currently, this detection technology is available from a small wireless unit (VD) which is installed, by core drilling a small hole in the surface of the carriageway (geomagnetic detector) to measure the Earth's magnetic field change when a vehicle passes by. This will be t ransit as a wireless signal to Routers under 2.4GHz wireless frequency, which can be processed by a Data Acquisition Center Device to generate a variety of traffic data, including vehicle presence signal, speed, headway time, occupancy time, vehicle distance, vehicle length and road saturation
