 Research Pays Off: Automated Speed Enforcement Slows Down Drivers in Work Zones
January 26, 2012
More than 7,000 crashes occur annually in highway work zones in Illinois, causing approximately 2,000 injuries. The number of work zone fatalities in the state reached a peak of 44, including 5 workers, in 2003. Speeding is one of the most important contributors, affecting the frequency and severity of work zone crashes. In 2004 the Illinois Department of Transportation deployed two self-contained vans to implement a legislatively mandated speed-radar photo enforcement (SPE) program in work zones on highways. The speeds of vehicles approaching the SPE vans are monitored with two radar systems: down-the-road radar and across the-road radar.
