Executive Summary for the Western Transportation Institute’s Augmented Speed Enforcement Project

The purpose of the augmented Speed Enforcement (aSE) project is to detect and warn speeding vehicles in a work zone and provide warnings to work zone workers. One system comprises traffic drums positioned adjacent to orange cones marking the work zone lane closure. When a speeding vehicle is detected, the driver and workers are warned. Daily deployment and retrieval of the system is labor intensive and time consuming. Evaluation of speed data appears to show that the system does have an impact in reducing overall average speed and percentage of vehicles traveling at high speeds.
