Work Zone Data Exchange Specification Version 3.0 Informational Webinar

The Work Zone Data Working Group under the Federal Geographic Data Committee Releases Version 3.0 of the Work Zone Data Exchange Specification

The Work Zone Data Working Group (WZDWG), established under the Federal Geographic Data Committee Transportation Subcommittee, recently published version 3.0 of the Work Zone Data Exchange (WZDx) Specification based on prioritized issues and new insights from the data producer and data consumer community. The WZDx Specification enables infrastructure owners and operators (IOOs) to make harmonized work zone data available for third-party use. The specification is intended to make travel on public roads safer and more efficient through ubiquitous access to data on work zone activity.

Changes introduced via WZDx v3.0 will improve usability and consistency, including the standardization of lane sequencing and version formatting, additional properties to support detour information and other road events for implementing agencies, and relationship entities to describe correlations between road events and work zone phases (i.e., non-WZDx entities on the road).

WZDx Specification Version 3.0 Release Informational Webinar

To support roadway operators and agencies considering the establishment of their own WZDx-compliant feed, as well as data users considering ingesting WZDx data, the U.S. DOT is hosting a public release webinar, or virtual information session, on the changes made to the WZDx Specification for its v3.0 release. The webinar is scheduled for September 28, 2020, from 1:00 pm to 2:00 pm EST.
