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.
