Developed in 2005, the General Transit Feed Specification (GTFS) is making transit trip planning easier by allowing public transportation agencies to share transit schedules in an electronic format that can be used by a variety of trip-planning applications, such as Google Maps. The GTFS can be used to share static transit schedules (GTFS-s) or provide real-time information on transit vehicle arrivals and departures (GTFS-r). As a part of this project, we have collected data on the adoption and publication of both types of GTFS data by transit agencies in California.
The reports and maps below display and analyze our data on the adoption of both types of feeds. Click on each image to load an interactive version of the map.
California Transit Agencies
Methodology: This data was collected in March 2020, and contains data on GTFS-s and GTFS-r adoption for 172 transportation agencies in California listed in the National Transportation Database. Data on GTFS feed availability was web-scraped from Open Mobility Data and paired with transportation agency route shape files to map adoption across California agencies.
