Project Title:
  Speed Photo-Enforcement in Illinois Work Zones
Start Date: 7/1/2005
End Date: 6/30/2008
Summary of Project:
  The Illinois Department of Transportation (IDOT) is interested in evaluating the effects using speed photo enforcement (SPE) systems on traffic flow characteristics and safety in work zones (WZ). Two self contained vans equipped with the photo enforcement system will be provided by a vendor. The University of Illinois (UI) research team will evaluate the system performance. The effectiveness of SPE will be determined using criteria such as: speed reduction, speed variation/uniformity, speeding violations issued, speeding tickets contested in court, and other very similar criteria.
Objective of Project:
  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.
Expected Outcome:
  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.
