Exporting a GTFS File

General Transit Feed Specification (GTFS) is one of the most common open-standard data formats for public transport information schedules, making it a popular format for continuing to share and edit networks outside Podaris.

Exporting GTFS Networks

Once you have created a transport network or imported and made changes to an existing network (see Uploading a GTFS File), you may wish to export it using the GTFS feed export function in Podaris to:

 

  • Edit a GTFS feed
  • Add route shapes and geometry for a feed that doesn’t have one
  • Create a smaller extract from a larger feed i.e. for an area of a single agency
  • Convert a feed with frequency-based trips to trips-only
  • Convert a TransXChange file to a GTFS-file

GTFS feeds can be exported in Podaris:Plan from the Export Project menu, accessible from the Project Menu, selecting the GTFS format.

Only currently visible transport routes and stations will be exported. The visibility of routes and stations can be toggled on and off with the Hide/Show button (shown below for routes).

route visibility

Before exporting, you will be asked to specify three export options, these are:

  1. Use Podaris IDs? When you import a network into Podaris, services are given a Podaris ID as well as their ID from the original GTFS. This setting allows you to choose which ID will be exported. Select ‘yes’ to override any agency, stop and route IDs from the original GTFS. The exported GTFS will instead have unique ID’s, generated from Podaris. Select ‘no’ if you want to retain the original GTFS agency, stop and route IDs. 
  2. Include parent stops even if hidden? Within Podaris you are able to group stations, making individual stations “children stations” with a “parent station” for the group. This setting allows you to decide whether these parent stations should be included in your outputted GTFS. Including parent stations can be useful when networks contain complex stations with multiple platforms, or which serve multiple routes, and you want to be able to simplify the network for further analysis.
  3. Use trip names as trip IDs? When combined with the “Create individual trips?” option available when importing a network, this setting allows you to export the network with the same trip IDs as the imported GTFS.
