Technical Evaluation of Road Working Area Safety Systems and Traffic Sensors

Speeding is a significant contributor to a significant portion of highway collisions. For work zones in particular, the speeding problem is compounded by on-site road re-configuration, narrowed lanes, or poor visibility. This paper describes a recent study in California that is designed to assess the technical performance of automated speed enforcement (ASE) equipment in the field. Several traffic monitoring systems were field tested with an automated speed enforcement system at a study site in California. The study site was located on a rural two-lane highway, where severe collisions occurred frequently and speeding appeared to be a significant factor. The ASE equipment and other devices were found to detect 2-5 % of passing vehicles to travel in excess of 65 mph in a highway with a posted speed limit of 55 mph.
