Work Zone Data Initiative 

Work Zone Activity Data (WZAD) is the “what,” “where,” and “when” of work zone activities. FHWA’s Work Zone Data Initiative (WZDI), launched in 2017, is an effort to enable easier sharing and application of WZAD across the country. To facilitate collaboration, this page provides more information on WZDI and includes resources such as presentations and program materials.

This page also includes information on the USDOT’s Work Zone Data Exchange (WZDx) project, a multi-agency collaborative effort, focused on making travel safer and more efficient through ubiquitous access to work zone activity data. Current efforts are focused on jumpstarting the voluntary adoption of a basic work zone data specification, which enables infrastructure owners and operators to make harmonized work zone data available for third party use. Longer term, the project aims to get data on work zones into vehicles to help automated driving systems (ADS) and human drivers navigate more safely.
