    • Maricopa County Regional Work Zone Data Exchange (WZDx) v3.0 Feed Sample

    Metadata Updated: October 28, 2025

    The WZDx Specification enables infrastructure owners and operators (IOOs) to make harmonized work zone data available for third party use. The intent 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.

    MCDOT leads the effort to aggregate and collect work zone data from the AZTech Regional Partners. The live feed is currently compliant with WZDx specification version 3.0.

    The ITS JPO has collections from 23 states including Arizona covering various parts of the time period from 10/2019 to 08/2024 depending on when the feed was active. The data is split into two archive files, the raw data contains the collection of .json or .geojson files exactly as they were on the individual state’s WZDx feed at the time of collection. The processed data is organized by work zone, so that as information about the work zone changed through feed updates they would be collected in a single file for that work zone.
