Transportation Data Exchange Initiative
Improving travel experiences through open transportation data exchange
The University of Washington's Transportation Data Exchange Initiative (TDEI) is improving the quality, efficiency and interoperability of transportation services by standardizing how transportation data is structured and shared. This approach is being used in Washington, Oregon, and Maryland.
