2.3. Reading data: GTFS¶

This page goes through methods for reading in GTFS (General Transit Feed Specification). Here is the reference page for the schema of GTFS data.

GeNet ingests zipped or unzipped GTFS feeds. The following files are required in the unzipped folder, or inside the zip file:

• calendar.txt
• stop_times.txt
• stops.txt
• trips.txt
• routes.txt

When reading a GTFS feed, GeNet expects a date in YYYYMMDD format. It will raise an error if the selected date yields no services.

GeNet does support extraction of services/routes/stops in the output genet.Schedule object based on a geographical area (Methods: services_on_spatial_condition, routes_on_spatial_condition, stops_on_spatial_condition, more information in notebook on using genet Network), but you might like to use gtfs-lib prior to ingestion in GeNet.

The user assumes responsibility for the quality of their input GTFS feed. There are various validation tools that can be used with GTFS feeds before using with GeNet, see this page for a summary of validation tools.

GTFS is assumed to be in epsg:4326, you need to project the Schedule to projection you require.
