Work zones have become the rule rather than the exception on highways today. Work zones are a major contributor to the delay experienced by motorists. Compounding this issue of work zones and delay are the increasing traffic volumes on our roadways. Data show that truck travel in the United States is increasing at a much faster rate than the overall vehicle travel (total VMT) and this growth trend is expected to continue. Therefore, designing any effective traffic management strategies should explicitly consider truck drivers and their response to such systems.

Intelligent transportation systems (ITS) such as advanced traveler information systems (ATIS) can be used to effectively manage the demand and available capacity in work zones and mitigate the mobility impacts of work zones. However, designing effective ATIS systems requires an understanding of drivers’ perception and understanding of the provided information, their decision-making and consequent reaction. None of the studies focused on vehicle type, specifically trucks and how the ATIS affected their diversion.

This proposal presents a plan to address the issues of truck drivers’ responses to real-time travel information, their willingness to take alternate routes, and the factors that affect their choice in order to design effective truck traffic management systems.


  • Develop an understanding of truck drivers’ diversion behavior and decision resources when provided with real-time information,
  • Develop guidelines for designing effective truck traffic management systems in work zones.
