WZDx Demonstration Grants

The U.S. Department of Transportation (USDOT) released a $2.4M Notice of Funding opportunity (NOFO) for the Work Zone Data Exchange (WZDx) Demonstration, which closed on August 3, 2020. The purpose of this research program is to increase the safety of the traveling public through the production of consistent public work zone data feeds across jurisdictions. This is an one-time funding opportunity for public roadway operators to make unified work zone data feeds available for use by third parties and collaborate on the WZDx Specification development.

In January 2021, the USDOT Federal Highway Administration awarded $2.4 million in WZDx demonstration grants to fund projects in 13 states.

State Project Description Grant
Arizona The County of Maricopa, along with Arizona Department of Transportation and partner agencies, will extend a pilot WZDx data feed to the entire county, including local, regional and national highway system.
California Metropolitan Transportation Commission will update the 511 SF Bay system to generate WZDx data feeds.
Colorado Colorado Department of Transportation will pilot the use of an autonomous truck mounted attenuanator to provide a real-time data feed for the work zone in which the attenuator is used.
Georgia Georgia Department of Transportation will extend existing lane closure system to include new data capture and exhange capabilities to produce WZDx feeds.
Iowa Iowa Department of Transportation will demonstrate the use of smart arrow board technology to provide validated and granular information for WZDx data feeds statewide.
Maryland Maryland State Highway Administration will produce a statewide WZDx data feed and integrate it with the University of Maryland's Regional Integrated Transporation Information System (RITIS) platform for distribution.
Massachusetts Massachusetts Department of Transportation will extend the WZDx specification to include Smart Work Zone Data, specifically including field device information and traffic metric data.
Minnesota Minnesota Department of Transportation will generate WZDx data feeds statewide and create a mobile tool for workers to check-in to a work zone when beginning work, advancing safety, efficiency, and innovation.
Missouri St. Charles County will develop a corridor level deployment of new WZDx-compliant data feed for cities and counties within the county.
Utah Utah Department of Transportation will demonstrate WZDx data feed deployment across six work zones in urban, rural and freeway environments.
Virginia Virginia Department of Transportation will generae WZDx data feeds for all work zones statewide.
Washington Washington Department of Transportation will pilot WZDx data feed deployment by automating data gathering and validation for work zones and other non-recurring events requiring temporary traffic control
Wisconsin Wisconsin Department of Transportation will extend the capacity of the Advanced Traffic Management System (ATMS) to produce a statewide data feed.
