TRC2301 - Smart Work Zone (SWZ) System, Design, Specifications, Estimates, and Implementation Guidelines

The ability to manage traffic through highway work zones is rapidly improving. Portable Intelligent Transportation System devices can detect slowing traffic and push alerts to the contractor, Resident Engineer, Transportation Management Center, and drivers’ smartphone apps such as Waze or Google Maps. Smart arrow boards can inform stakeholders of lane closures in real-time. Dynamic speed limits based on work zone conditions are successfully used in many states. Third-party providers that push data to consumers via smartphone apps can also detect and impute traffic conditions near work zones. This research will inform the development of a Smart Work Zone (SWZ) special provision to replace the Automated Work Zone Information System special provision for highway contracts. Specific objectives intend to provide a process that will assist in identifying the need for an SWZ earlier in the project development process, consider when to use specific new technologies, and better design and estimate SWZ costs.
