GTFS Adoption in California

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.

GTFS Adoption by Transit Agencies in Southern California

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.
