Abstract

An induction vehicle detection and identification system comprising electronic identification devices with electronic memory, mounted on vehicles, and a reader capable of reading and/or writing data obtained from devices in HF-band. Devices have a non-volatile memory and are integrated into the vehicle'"'"'s license plate. The reader combined with a magnetic frame is in a dielectric casing, which is mounted under the roadway. It generates an alternating magnetic field, which determines the detection and identification range. Minimum time the reader requires to read discrete responses generated by electronic identification devices and to identify the vehicle is less than 25 ms. The identification devices and the reader exchange data at the rate of 1 Kbit/sec or higher, and provide data encoding and decoding, as well as data access restriction.
