Vehicle detectors are key components of all street and freeway traffic control and surveillance systems. Detector requirements for these applications include: low cost, accurate detection, minimum installation time and cost, reliable under all environmental conditions, low maintenance and calibration requirements, and ability to detect all vehicles on any standard roadway surface. An advanced vehicle detector concept called the Self-Powered Vehicle Detector (SPVD) was examined by this project. The SPVD is a new traffic detector consisting of a magnetometer sensor, RF communication link, and self-contained battery source. It is packaged into a small cylinder designed to be placed in roadway bore holes, completely under the roadway surface. Vehicles are detected and this information is transmitted by RF communication to a receiver in a traffic control enclosure up to 500 feet distant. SPVD operational life-time is at least one year. The SPVD is an advanced new approach to reducing installation cost. Its feasibility was proven using three SPVD Engineering models in this project. /FHWA/
