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. A continuously updating archive of the WZDx feed data can be found at ITS WorkZone Data Sandbox. The live feed is currently compliant with WZDx specification version 3.0.

The National Bicycle Network is a geospatial dataset for nationwide bicycle routes. It is based on data and information released by public agencies such as state transportation departments, local Metropolitan Planning Organizations, local Councils of Government, city, and county public works and transportation departments. The FHWA Office of Highway Policy Information (HPPI) integrates all releases into one nationwide bicycle network, construction, and operating of such facilities as a safe, efficient, and equitable travel mode.

2015 Traffic Volume Data - FHWA's TMAS Data Program (based on unweighted raw continuous traffic count information collected by state highway agencies)

This dataset offers insight on weekly fluctuation of the gasoline product supply, which is an important part of any analysis of construction trends, materials and operating costs associated with highway repair and construction, and changes in traffic volume. These data come directly from the Energy Information Administration (EIA) website. The EIA publishes the average daily amount of gasoline supplied in barrels, which HPPI converts to an average number of gallons of gasoline per week.

This data set is to hold some SBIR Documents to be released.

UPACS stands for the User Profile and Access Control System. UPACS is the security control system that manages user authentication and associated access rights for individuals needing entry into one of FHWA's Information Systems.
