  • Optronic system for the measurement of vehicle traffic
    Patent number: 6750787
    Abstract: The present invention is a vehicle traffic measurement system designed to accurately count and record the number of vehicles passing through a selected location, to more accurately determine and record the velocity at which the individual vehicles travel through that location, and to accurately determine and record in which relative direction the vehicles are traveling as they pass that location. The basic physical principle is of a moving object interrupting two parallel light beams a known reference distance apart, and information extracted from the interruptions sensed and electronically processed into count, direction, and velocity being recorded for subsequent data analysis.
