What does each GTFS file contain
The content below is based on the official GTFS Specification, developed by the GTFS community and published at https://developers.google.com/transit/gtfs/reference/.
We modified the version below to describe the feeds published by Trafiklab. Fields and files that are not included in any Trafiklab feed are not described below. For the latest version or in case of conflict, refer to the official documentation.
- In the tables below, the column ‘available in dataset’ will be bold if the field is always present and not bold if it is not always present.
agency.txt
| Field Name | Type | Available in dataset | Description |
|---|---|---|---|
agency_id | ID | All | Uniquely identifies a transit agency. Note that in some cases, such as when a single agency operates multiple separate services, agencies and brands are distinct. This document uses the term “agency” in place of “brand”. A dataset may contain data from multiple agencies. |
agency_name | Text | All | Full name of the transit agency. |
agency_url | URL | All | URL of the transit agency. |
agency_timezone | Timezone | All | Timezone where the transit agency is located. If multiple agencies are specified in the dataset, each has the same agency_timezone. |
agency_lang | Language code | All | Primary language used by this transit agency |
agency_fare_url | URL | GTFS Regional | URL of a web page that allows a rider to purchase tickets or other fare instruments for that agency online |
The following excerpt gives some example values for the different fields.

| Field Name | Type | Available in dataset | Description |
|---|---|---|---|
route_id | ID | All | Identifies a route. |
agency_id | ID referencing agency.agency_id | All | Agency for the specified route. This field is required when the dataset provides data for routes from more than one agency in agency.txt, otherwise it is optional. |
route_short_name | Text | All | Short name of a route. This will often be a short, abstract identifier like “32”, “100X”, or “Green” that riders use to identify a route, but which doesn’t give any indication of what places the route serves. Either route_short_name or route_long_name must be specified, or potentially both if appropriate. |
route_long_name | Text | All | Full name of a route. This name is generally more descriptive than the route_short_name and often includes the route’s destination or stop. Either route_short_name or route_long_name must be specified, or potentially both if appropriate. |
route_type | Enum | All | Indicates the type of transportation used on a route. |
route_url | URL | None | URL of a web page about the particular route. Should be different from the agency.agency_url value. Not used. |
route_desc | Text | GTFS Regional | Description of a route that provides useful, quality information. Should not be a duplicate of route_short_name or route_long_name. |
The GTFS standard defines 9 route_types, but all Trafiklab feeds make use
of
extended route types. Check the
feed-specific documentation for examples.
The following excerpt shows some example values.

| Field Name | Type | Available in dataset | Description |
|---|---|---|---|
route_id | ID referencing routes.route_id | All | Identifies a route. |
service_id | ID referencing calendar.service_id or calendar_dates.service_id | All | Identifies a set of dates when service is available for one or more routes. |
trip_id | ID | All | Identifies a trip. |
trip_headsign | Text | GTFS Sverige 2 | Text that appears on signage identifying the trip’s destination to riders. Use this field to distinguish between different patterns of service on the same route. If the headsign changes during a trip, trip_headsign can be overridden by specifying values for the stop_times.stop_headsign. |
trip_short_name | Text | GTFS Sverige 2 | Public facing text used to identify the trip to riders, for instance, to identify train numbers for commuter rail trips. If riders do not commonly rely on trip names, leave this field empty. A trip_short_name value, if provided, should uniquely identify a trip within a service day; it should not be used for destination names or limited/express designations. |
direction_id | Enum | GTFS Regional | Indicates the direction of travel for a trip. This field is not used in routing; it provides a way to separate trips by direction when publishing time tables. Valid options are: 0 - Travel in one direction (e.g. outbound travel). 1 - Travel in the opposite direction (e.g. inbound travel). |
shape_id | ID referencing shapes.shape_id | GTFS Regional | Identifies a geospatial shape describing the vehicle travel path for a trip. |
The following excerpt shows what a trips.txt file can look like:
1route_id,service_id,trip_id,trip_headsign,direction_id,shape_id

lever (route) or lower level (stop time).
stop_times.txt
A stop time is a certain trip picking up or dropping of passengers at a certain stop, at a certain time.
| Field Name | Type | Available in dataset | Description |
|---|---|---|---|
trip_id | ID referencing trips.trip_id | All | Identifies a trip. |
arrival_time | Time | All | Arrival time at a specific stop for a specific trip on a route. If there are not separate times for arrival and departure at a stop, enter the same value for arrival_time and departure_time. For times occurring after midnight on the service day, enter the time as a value greater than 24:00:00 in HH:MM:SS local time for the day on which the trip schedule begins.Scheduled stops where the vehicle strictly adheres to the specified arrival and departure times are timepoints. If this stop is not a timepoint, it is recommended to provide an estimated or interpolated time. If this is not available, arrival_time can be left empty. Further, indicate that interpolated times are provided with timepoint=0. If interpolated times are indicated with timepoint=0, then time points must be indicated with timepoint=1. Provide arrival times for all stops that are time points. An arrival time must be specified for the first and the last stop in a trip. |
departure_time | Time | All | Departure time from a specific stop for a specific trip on a route. For times occurring after midnight on the service day, enter the time as a value greater than 24:00:00 in HH:MM:SS local time for the day on which the trip schedule begins. If there are not separate times for arrival and departure at a stop, enter the same value for arrival_time and departure_time. See the arrival_time description for more details about using timepoints correctly.The departure_time field should specify time values whenever possible, including non-binding estimated or interpolated times between timepoints. |
stop_id | ID referencing stops.stop_id | All | Identifies the serviced stop. All stops serviced during a trip must have a record in stop_times.txt. Referenced locations must be stops, not stations or station entrances. A stop may be serviced multiple times in the same trip, and multiple trips and routes may service the same stop. |
stop_sequence | Non-negative integer | All | Order of stops for a particular trip. The values must increase along the trip but do not need to be consecutive. Example: The first location on the trip could have a stop_sequence=1, the second location on the trip could have a stop_sequence=23, the third location could have a stop_sequence=40, and so on. |
stop_headsign | Text | GTFS Regional | Text that appears on signage identifying the trip's destination to riders. This field overrides the default trips.trip_headsign when the headsign changes between stops. If the headsign is displayed for an entire trip, use trips.trip_headsign instead.A stop_headsign value specified for one stop_time does not apply to subsequent stop_times in the same trip.ℹGTFS Regional specifies the stop_headsign for each stop |
pickup_type | Enum | All | Indicates pickup method. Valid options are:0 or empty - Regularly scheduled pickup.1 - No pickup available.2 - Must phone agency to arrange pickup.3 - Must coordinate with driver to arrange pickup. |
drop_off_type | Enum | All | Indicates drop off method. Valid options are:0 or empty - Regularly scheduled drop off.1 - No drop off available.2 - Must phone agency to arrange drop off.3 - Must coordinate with driver to arrange drop off. |
shape_dist_traveled | Non-negative float | GTFS Regional | Actual distance travelled along the associated shape, from the first stop to the stop specified in this record. This field specifies how much of the shape to draw between any two stops during a trip. Must be in the same units used in
shapes.txt. Values used for shape_dist_traveled must increase along with stop_sequence; they cannot be used to show reverse travel along a route.Example: If a bus travels a distance of 5.25 kilometers from the start of the shape to the stop, shape_dist_traveled=5.25. |
timepoint | Enum | GTFS Regional | Indicates if arrival and departure times for a stop are strictly adhered to by the vehicle or if they are instead approximate and/or interpolated times. This field allows a GTFS producer to provide interpolated stop-times, while indicating that the times are approximate. Valid options are:0 - Times are considered approximate.1 or empty - Times are considered exact. |
Stop_times.txt is usually the largest file in a GTFS feed. Depending on the hardware and
programming language, it can be computationally intensive to read all the data. Make sure you read this file in an
efficient way (for example by caching data, not reading the entire file into memory, …).
