The Self-Powered Vehicle Detector was designed to detect reliably vehicles passing through a desired surveillance zone under all environmental conditions from its fixed location beneath the roadway. The magnetic signature of the detected vehicle can then be telemetered via a radio frequency link to a roadside traffic instrumentation enclosure for vehicle counting or traffic control. This final report covers all SPVD research and development in seven major areas of investigation: Magnetometer development, sensor system electronics, telemetry link encoder/decoder, telemetry link oscillator/transmitter, antenna, telemetry receiver and battery evaluations, and mechanical component design and development.
