Abstract:Video cameras and computer image processors have come into widespread use for the detection of
vehicles for signal actuation at controlled intersections. Video is considered both a cost-saving and
convenient alternative to conventional stop-line inductive loop detectors. Manufacturers’ specification and
performance statements vary in the metrics used and data reported, and are inconsistent between
available products. The lack of common test standards and procedures has made product selection and
optimal deployment decisions difficult for local jurisdictions as well as Caltrans. Performance of these
systems is difficult to ascertain by simple observation of signal actuation.
