AWIZ: Smart Work Zone Systems

Automated Work Zone Information Systems (AWIZ) are smart work zones that integrate technology with equipment in highway construction applications. Equipment is connected by wireless technology to send and receive road conditions and warnings. Motorists receive real-time information about upcoming traffic conditions and potential hazards.

Automated End of Queue Warning Systems are a work zone intelligent transportation system consisting of a set of roadside speed sensors and portable changeable message signs (PCMS). The system has a customizable speed threshold to accurately detect queued traffic. This information is then relayed to responsive message boards that transmit warning messages to drivers upstream of the work zone.
