General errors

You can identify and fix errors that can cause issues with your feed and trips.

Important: If you're located in a country where English isn't the native language, all errors errors show up in English.

Feed expiration
Error in English: Feed expiration

The majority of services in a feed expire within 60 days. To avoid gaps in service for users, feeds must include the current date along with dates in the near future.

Learn more about feed expiration and guidelines for feeds.

Feed has no calendar date exceptions
Error in English: Feed has no calendar date exceptions

The feed has more than 6 months of data, but  doesn’t define calendar exceptions for holidays or other service modifications in the calendar_dates.txt file. This may cause problems since most feeds have service exceptions over long time frames.

If your feed doesn’t contain calendar date exceptions, ignore this warning.

Learn more about guidelines for feeds.

Match stop to shape
Error in English: Match stop to shape

It’s common to match stops with shape data for routes and trips. The shapes.txt file can define the travel path for a particular trip. In trips.txt, you can link the trip to a shape with the shape_id field.

A trip also defines a sequence of stops in the stop_times.txt file for the stops visited during the course of the trip. To show the path of travel between 2 stops in routing results, you can define the shape for a trip to match the sequence of stops to their closest location along the trip shape.

Our GTFS validation tool often reports 2 common warnings for stop-to-shape matching. Follow the links for specific guidance on diagnosing those issues.

Complex trip shapes

It can be tricky to match stops to a trip shape when a trip has a complex geometry, such as loops or overlapping sections. Our software does its best to match a stop to its best location along a shape. When that process fails, it may indicate a problem with your shape data, stop locations, or the stop sequence of a trip.

For complex shape and stop sequences, the GTFS specification provides a way to define how stops are matched to the trip shape

  • The shapes.txt file defines a shape_dist_traveled field, which can specify the distance along the shape for each point of the shape
  • The stop_times.txt file also defines a shape_dist_traveled field, which can specify distance along the shape for each stop along a trip

When both fields are defined for the shape and each stop belongs to a trip, the distance values can explicitly determine where each stop matches to a shape.


The trips.txt file


The shapes.txt file


The stop_times.txt file


The example shows a simple trip with a simple shape of 2 stops, and shape_dist_traveled values for both the shape and each stop.

First, stop0 has a shape_dist_traveled value of 50. Our shape points show that 50 falls between the first 2 points, which have shape_dist_traveled values of 0 and 100, respectively. That puts the stop-to-shape match roughly halfway between the 2 shape points at approximately 47.05, -122.0.

Next, stop1 has a shape_dist_traveled value of 175, which puts it between the last 2 shape points. Since the stop is about 3/4 of the way between the 2 points according to the shape distance, the stop-to-shape match is approximately 47.1, -122.75.

You can use whatever units you prefer for shape_dist_traveled values, such as meters or feet. Feed consumers won’t assume particular units. Instead, the values can only be used to determine how a stop matches positions along a shape.

No transit schedule data available
Error in English: No transit schedule data available

If you get a "Sorry, we don't have transit schedule data at the time and date you specified" error message, you may have a trip plan that doesn't have any feasible results at the specified time. This may happen because of at least one of the following causes:

  • At the time and date you specified, there’s no scheduled service in the next 24 hours.
  • There's scheduled service, but the GTFS feed doesn’t include these trips because either the feed expired or there’s an error in the feed.
  • The trip is more than 2 months in the future. Google Maps only supports trip routes that begin in the next 2 months.
Search for transit stations or stops
Error in English: Search for transit stations or stops
It may take up to 48 hours after you launch a stop or station for it to show up on Google Maps. Please be patient and try again at a later time.
Submit fares for multiple agencies

Error in English: Submit fares for multiple agencies

To submit fares for multiple agencies in your feed, add a column “agency_id” into fare_attributes.txt. Then, for each fare, fill in the agency_id.

Tip: A fare can only belong to one agency. To have a fare that belongs to several agencies, you must duplicate the fare.

Trip option suggests travel by foot instead of public transport
Error in English: Trip option suggests travel by foot instead of public transport

If it takes less time to go by foot, a trip option may suggest to travel by foot instead of public transport.

If you’re the agency, make sure to provide arrival and departure times for all stops in a trip. Stops without arrival times are scheduled based on the nearest preceding timed stop.

Transit area not covered
Error in English: Transit area not covered
If you get a "This area isn't covered" error message, check that your query date or time is set to ”Today.”
If the information still isn’t available, notify the Google Transit team.
