Abstract |
Because of increasing difficulties in enforcing speed limits on high-speed, high-volume roads, it was proposed that experiments be conducted with photo-radar to determine whether using it could help reduce average speed and speed variance. It has been widely used in Europe for about 30 years and very recently used in the western United States. A project task force led by researchers from the Virginia Transportation Research Council conducted site visits to cities in Europe and the United States where photo-radar is being used. The task force also invited five manufacturers of photo-radar equipment to demonstrate their equipment during a 2-week series of tests on sections of U.S. Interstate highways with varying volumes of traffic and differing traffic characteristics. The tests were designed to provide the researchers with data on the accuracy, reliability, and efficiency of each unit and help them determine whether photo-radar could be successfully deployed as an enforcement tool on high-speed high-volume roads. The researchers concluded that four of the five photo-radar units tested in the study met the minimum standards for accuracy, reliability, and efficiency established by the evaluators in conjunction with the project task force and therefore recommended efforts to pass enabling state statutes and test further the efficacy of using photo-radar under actual traffic-enforcement conditions.
