Augmented Speed Enforcement Project at UC Berkeley - Executive Summary

In this project, a speed alert and augmented enforcement system (aSE) was developed with a combination of sensing, image processing and recognition, wireless communication. The system includes a speed camera that captures speeding vehicles, and a changeable message sign that displays speeder’s license plate number and measured speed, and a web page that allows police officers to monitor the incidence of violators traveling at excessive speeds. The aSE system was field tested for a work zone application on a rural highway. With data collected over multiple weeks, under a baseline scenario without the use of the aSE system and test cases with the system, it was shown that the system was effective in reducing the number of vehicles moving in excess of the speed limit
