Use of Videotape in HOV Lane Surveillance and Enforcement: A Technology Sharing Reprint

摘要

The report describes the results of tests using video equipment to determine vehicle occupancy, document violator identity, and aid enforcement on high occupancy vehicle, (HOV) lanes. Cameras were set up on and under freeway overpasses, and the findings from observers using video were compared with those of police officers downstream, and observers on the overpasses not using the equipment. The tests showed that it is technologically possible to record several accurate views of vehicles traveling in mainline HOV lanes. Polarizing filters help to solve problems with glare from shiny cars and windshields. No combination of recorded views currently provides enough information to support prosecution for occupancy violations on that evidence alone, although the technique can support on-line enforcement and lane performance monitoring.
