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.
