Traffic Detector Video Training Course - Part 1 - Detector Theory

Federal Highway Administration Video VH-584 Traffic Detector Video Training Course - Part 1 - Detector Theory This training course on traffic detectors provides an understanding of how detectors work and the best methods to install, maintain, and repair them. The course is divided into four parts: detector theory, applications and evolution; detector design; detector installation; and detector maintenance. The training course introduces pressure, push button, magnetic, magnetometer, inductive loop, radar, sonic, radio frequency, and light emission detectors, with emphasis on loop detectors; for application at isolated intersections, in arterial or open network systems, in closed network systems, for area-wide system control, for preemption and priority vehicle control and pedestrian signal control; and in conjunction with pretimed, semi-actuated, fully-actuated and volume density controlled signal timing plans.
