An active-infrared overhead vehicle sensor capable of detecting vehicle (moving or stationary) presence, classifying type of vehicle, and measuring vehicle speed is described. The results of tests conducted at a street intersection in Orange County, Florida are presented. The test results demonstrate that the sensor reliably (99.4 %) detects vehicles including cars, trucks, buses, and motorcycles and measures their speed to within plus/minus 1 mi/h (1.6 km/h) at speeds up to at least 50 mi/h (80 km/h).
