Final Report for the Western Transportation Institute's Augmented Speed Enforcement Project

The augmented Speed Enforcement (aSE) project developed systems to detect speeding vehicles in a work zone and provide warnings to both the vehicle driver and work zone workers. The system consists of 28 orange traffic drums (smart drums or sDrums) positioned adjacent to orange cones marking the work zone lane closure. When the system detects a speeding vehicle, it synchronously flashes the orange lights on top of the drums, warning the driver to slow down and the workers of a speeding vehicle. If the vehicle speed is above a set trigger speed, the systems activates a pager system to warn the workers of the speeding vehicle. System effectiveness and deployability were evaluated for four weeks near Los Banos, CA. Daily deployment makes the system labor intensive and time consuming.
