This dataset provides archived lane closure occurrences within the Iowa Department of Transportation (IDOT) highway system in a tabular format. The ITS JPO has collections from 23 states including Iowa 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. To request access fill out the form here.

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.

ITS DataHub has partnered with the work zone data community, Federal Highway Administration's (FHWA) Work Zone Data Initiative (WZDI), and the broader Work Zone Data Working Group to create the following suite of proof-of-concept tools for work zone feeds compliant with the Work Zone Data Exchange (WZDx) specification. This data story describes those tools, focusing on the WZDx Feed Registry and the WZDx Data Archive.

The purpose of the data set is to provide multi-modal data and contextual information (weather and incidents) that can be used to research and develop applications for the USDOT Dynamic Mobility Applications (DMA) program. This legacy dataset was created before data.transportation.gov and is only currently available via the attached file(s). Please contact the dataset owner if there is a need for users to work with this data using the data.transportation.gov analysis features (online viewing, API, graphing, etc.) and the USDOT will consider modifying the dataset to fully integrate in data.transportation.gov.

A. SUMMARY This dataset contains upcoming and current permitted street and lane closures occurring as a result of the Shared Spaces program, certain special events, and some construction work. This dataset only includes street closures permitted by the San Francisco Municipal Transportation Agency (SFMTA). It doesn’t include street closures managed by other City departments such as Public Works or the Police Department. More details regarding these street closures can be found here. B. HOW THE DATASET IS CREATED The data is exported from the Street Closures Salesforce database maintained by the SFMTA ISCOTT unit and the construction closure Access database maintained by SFMTA STP unit. It is converted to the standard Work Zone Data Exchange (WZDx) format per the United States Department of Transportation (USDOT). More information is available from the USDOT's WZDx site and the official WZDx Specification on GitHub. C. UPDATE PROCESS This report is issued and posted here daily. D. HOW TO USE THIS DATASET The WZDx standard allows infrastructure owners and operators make harmonized work zone data available for third party use. The intended audience includes 511 and navigation systems (both for human drivers and automated driving systems). If you are looking for a format more suitable for mapping or analytics use cases, please see the following datasets: Temp Street Closures Temp Street Closure Intersections

This dataset contains V2X data collected from the Utah Connected Vehicle Data Ecosystem Program. We have submitted sample MAP messages in J2735 standards from 3 intersections in Orem, UT.
