After we have completed our quality assurance review of your GTFS feed and you have resolved any outstanding issues, you are ready to launch the feed. Google will work with you to set the date on which your transit data goes live on Google Maps.
After your GTFS feed is live, consistently maintain your transit data to ensure that your feed remains up to date and to prevent feed problems. Please keep your contact information up to date so that Google can deliver feed notifications on a timely basis.
