Speed Photo-Enforcement in Illinois Work Zones

This study will evaluate the effects of using speed photo enforcement (SPE) systems on traffic flow characteristics and safety in work zones (WZ). The overall goal is to determine the effectiveness of SPE in work zones using criteria such as: speed, speeding tickets issued and fraction upheld as valid in courts. The net effects of SPE above and beyond the "typical" traffic control procedure IDOT uses in WZ will be determined. Effects of police presence, "YOUR SPEED IS" sign, and SPE van in work zone alone or in combination will be studied.
