- The Work Zone Data Working Group released version 4.2 of the WZDx Specification in February 2023. Please review the release notes for more information on the updates.
- WZDx v4.2 is the last version created under the Work Zone Data Working Group governance structure. The specification is being rolled into a formal standard by ITE (with partners AASHTO and NEMA) and SAE. To learn more about that effort and how to get involved, see the Connected Work Zones website.
The Work Zone Data Working Group (WZDWG), established in 2019 under the Federal Geographic Data Committee (FGDC) Transportation Subcommittee (TSC), maintains the WZDx Specification with the goal of publishing incremental updates to refine the features, attributes, and vocabulary needed to model work zone activity data. The Work Zone Data Working Group included five subgroups focused on different aspects of the specification and supporting the stakeholder community.
