Abstract : An improved self-powered vehicle detector (SPVD) uses a two-axis magnetometer in conjunction with digital nulling loops to sense a vehicle's magnetic signature and then telemeter vehicle presence information to a roadside receiver. The SPVD system includes a tone code transmitter and an omnidirectional microstrip antenna to simplify installation and maintenance of the SPVD. (Author)
