ABSTRACT
Smart work zone (SWZ) systems have received significant attention for improving work zone (WZ) safety and mobility. This pilot study evaluated the effectiveness of Active Work Zone Awareness Devices (AWADs), connected vehicle technologies, law enforcement (LE), and their combinations in improving WZ safety on arterials. Vehicle speed data and driving behavior data were collected at seven sites in Florida that cover various WZ types, roadway classifications, and traffic conditions. Statistical comparisons indicated decreased speeds entering arterial WZs by 10%, increased safe driving behavior by 39%, and reduced risky driving by 44% by deploying AWADs alone. Combining AWAD with the presence of LE increased safe driving behavior by 61% and reduced risky driving by 56%. iCone products that communicate WZ conditions or warnings with road users are anticipated to have an impact on reducing vehicle speeds if the message can be broadcast automatically via navigation systems in the future.
