Abstract:Temporary traffic control in work zones, often referred to as TTC, lead to several challenges in terms of safety for both crew workers and drivers in both rural and urban settings. The changes imposed by the work zone in the road operating conditions or alignment geometry, including the presence of temporary signs, channelizing devices, and barriers, lane merging, shifting or closing tapers, width changes, and equipment, personnel, and materials on the roadway, increase the driver workload and the risk of crashes. This report presents the results of a driving simulator research project that investigated the potential safety implications associated with severe injuries and fatalities related to the use of GPS while driving on a two-lane rural highway with work zones consisting of one-lane closures due to operations and maintenance activities. Specifically, the effects of distractions caused by the audible messages of an active GPS while approaching or entering the advanced warning area of the TTC and the drivers’ compliance with work zone regulations on the workspace were investigated.
