Work zones have been identified as one of the tougher environments for automated vehicles to navigate. In addition to rapidly changing conditions, work zone layouts can vary significantly across jurisdictions.


Ongoing efforts that should be taken into account include:

·         FHWA’s Projects on the Impacts of Automated Vehicles on Highway Infrastructure and the Work Zone Data Initiative

·         Pilot deployments, including those in Michigan, Texas, Ohio, and Maricopa County

·         ATSSA’s Smart Work Zone efforts




The objective of this research is to document best work zone practices for automated vehicles, connected vehicles, and vehicles using both technologies. These practices should include the physical characteristics of the work zone that the vehicle senses and the digital information supplied to the vehicle (including through the FHWA’s Work Zone Data Initiative). The best practices should cover the range from major construction projects to maintenance work zones (e.g., pothole filling) to moving maintenance activities (e.g., striping) to utility activities. As appropriate, the deliverables should discuss applicability to similar situations such as incident management and other lane closures. Whenever possible, information should be provided to allow agencies to evaluate the return on investment for alternative designs.
