Development of a Self Powered Vehicle Detector

Abstract

A battery operated motor vehicle detection system has been developed which detects a vehicle's magnetic signature, processes it and then transmits vehicle presence information from its roadway position to a nearby receiver control unit. The Self Powered Vehicle Detector (SPVD) is an advanced vehicle detector concept which requires minimum installation time and cost, little maintenance, and is capable of detecting vehicles on any standard roadway surface. The SPVD system consists of two units, the roadway implanted sensor and a control unit which is located inside a traffic instrumentation enclosure less than 500 feet away. The SPVD sensor unit is placed in a standard roadway bore hole located in the center of the lane just beneath the surface. The estimated lifetime for a traffic flux of 20,000 vehicles/day is greater than one year. Twenty SPVD systems have been fabricated for FHWA evaluation. (Author)
