This report is a status summary of vehicle detector technology that is utilized for traffic control and road counting applications. The report provides background information on vehicle detectors, a cataloguing of commerically available detector types, and a field response summary on current vehicle detector usage. The field response summary focuses on the inductive loop detector (ILD). ILD installation techniques, electronics types, problems, and current research are discussed. Novel installation methods for the ILD are also highlighted. The final section of the report describes current vehicle detection research activity. This includes: the radio frequency traffic sensor, the magnetic gradient vehicle detector, and the self powered vehicle detector. /FHWA/
