Abstract:

In recent years, numerous new and innovative technologies have been developed to make traffic operations through work zones safer and more efficient. Some of these technologies belong to the category of Advanced Traveler Information Systems (ATIS). Their main function is to disseminate travel-related information to drivers to enhance their decisions regarding the route they choose to take to their desired destination. The system can provide real-time information on travel times, travel speeds, delays, accidents, route closures and detours, and work zone conditions, among others. The information can be communicated through changeable message signs (CMS), highway advisory radio, Internet, or some other medium. The technology evaluated by this study is called Work Zone Speed Advisory System (WZSAS). The WZSAS is an enroute traveler information system whereby real-time speed advisory information is provided to drivers by means of portable changeable message signs strategically located in advance of diversion points upstream of a work zone. The objective of the WZSAS is to advise drivers of the speed of traffic in advance of a work zone and thereby encourage them to divert to an alternate route when there is congestion in the work zone.
