This dataset provides information on fixed-route transit stops for the State of Washington as of 8/15/22. Stop data was extracted from General Transit Feed Specification (GTFS) data. Because GTFS data is typically created and managed by each individual transit agency, WSDOT cannot guarantee the accuracy of these data.Most data points are provided direct from GTFS feeds according to the specification at https://gtfs.org/. The stop_id field has been prepended with a code for each agency to ensure every stop has a distinct stop_id.Some fields are added describing the frequency level of service at each stop, based on the levels and methodology described in the WSDOT Frequent Transit Service Study (more information at https://engage.wsdot.wa.gov/frequent-transit-service-study/)Please send comments and questions to gtfs@wsdot.wa.gov
