Work Zone Data Exchange (WZDx)

The Work Zone Data Exchange (WZDx) Specification enables infrastructure owners and operators (IOOs) to make harmonized work zone data available for third party use. The objective is to make travel on public roads safer and more efficient through ubiquitous access to data on work zone activity. Specifically, the project aims to get data on work zones into vehicles to help automated driving systems (ADS) and human drivers navigate more safely.

The website is maintained by the U.S. Department of Transportation (USDOT) and includes news, information on demonstration grants, specifications and more.
