Evaluating a Dynamic Lane Merge Smart Work Zone

Transportation agencies strive to ensure the safety and mobility of motorists, as well as the safety of workers, in highway construction work zones. In an effort to enhance safety and mobility, ADOT is implementing its second dynamic lane merge smart work zone (SWZ) project on Interstate 15 (I-15). ADOT installed the SWZ in one direction and a traditional work zone in the other direction. Sensors were installed in both directions to collect data on vehicle speeds through the work zones. ADOT is interested in evaluating the SWZ to better understand the potential impact on the type, location, and severity of crashes, as well as on congestion and mobility, in the work zones. Data on vehicle speeds and crashes collected from both the SWZ and the traditional work zone will enable a comparative analysis that will inform decisions regarding future construction work zones.
