ITS4US UW Transportation Data Exchange Initiative TDEI
What is the Transportation Data Exchange Initiative (TDEI)?
Cities, organizations, and individuals currently lack detailed, accurate, and standardized data on the locations of footpaths, cycle paths, sidewalks, and crossings. Moreover, there is inconsistent information about the attributes of these pathways that affect walking, rolling, and non-motorized travel, as well as a limited understanding of how these paths are connected or disconnected.
The OpenSidewalks project aims to address this data deficiency by proposing a) a robust data schema (OpenSideWalks or OSW) and b) a comprehensive data tools ecosystem that support collection and maintenance of sidewalk data (which we call the TDEI).
These resources are designed to give planners, policy makers, and community advocates the data they need to improve pedestrian infrastructure, particularly in historically underserved areas.
Current funding is provided by the USDOT/JPO ITS4US program under the University of Washington’s TDEI deployment project.
OpenSidewalks is led by the Taskar Center for Accessible Technology (TCAT) housed by the Paul G. Allen School for Computer Science and Engineering at the University of Washington.

Choose “All Released Datasets” near the top of the page and then choose “Filter” on the right side of the page, just below the “All Released Datasets” tab.
Set the “Project Group” filter to “US DOT ITS4US”
Set the Service to any of the 6 demonstration regions/counties that may be of interest to you. These are the regions for which data is available via the TDEI and the ITS4US grant.
You should now see a list of filtered files in the table–when you find the file(s) you wish to download, choose the kebab (three vertical dots) menu on that file and then choose “Download”, for each file of interest.
Your browser should begin downloading a zipped data file (in OSW format) for each file you requested.
