Aiming to apply to ITS field, an optical vehicle classifiable sensor was developed, and this sensor is capable of classifying the type of vehicle and measuring vehicle speed. This paper describes not just an operational principle but also a result of field test. This optical vehicle classifiable sensor is comprised of both an overhead typed sensor head and a vehicle classifiable unit. This over-head typed sensor utilizes laser range finding technology applying time-of-flight principle and is capable of measuring both a distance between the sensor and the vehicle surface and a velocity of vehicle utilizing two beams principle. As a result of field test, classifiable ability of 99.2% were realized and velocity accuracy of 1.2km/h (@1σ) was accomplished.
