MBTA GTFS documentation

Updated specification extension, archive, and licensing documentation for the MBTA's implementation of the General Transit Feed Specification (GTFS). Developers can follow this repository to stay updated on upcoming changes to the MBTA GTFS feed format.

This repository contains the following files:

• reference/gtfs.md describes the MBTA's implementation of GTFS, supplementing the official GTFS specification with local conventions and information about non-standard files and fields.

• reference/gtfs-realtime.md describes the MBTA's implementation of the Realtime extensions to GTFS, also known as GTFS-RT.

• reference/gtfs-archive.md provides information on archived versions of the GTFS feed, for those interested in viewing historical schedules.

• developers-license-agreement.pdf is the license agreement governing developers' usage of the MBTA's GTFS feeds.

Information on other data available from the MBTA, and resources for developers can be found at the MBTA Developers page.

zone_ids off for Chelsea + Westborough

It looks like the zone_id the stop.txt file for Chelsea (CR-zone-4, should be CR-zone-1A) and Westborough (CR-zone-8, should be CR-zone-7) are incorrect.

Duplicated ids found in: fare_products - The returned object is not a tidygtfs object

Hello,
I was running this project:

https://github.com/coding-to-music/r-stringlines-nyc-mta-gtfs-train-visualization

And I saw an error using tidytransit with the MBTA GTFS feed, a new file fare_products.txt

#34

produces this error when running the R program:

# This may be unrelated, not sure:

Error in UseMethod("group_by") :
  no applicable method for 'group_by' applied to an object of class "NULL"
In addition: Warning message:

# This is the actual error:

In gtfs_to_tidygtfs(g, files = files) :
  Duplicated ids found in: fare_products
The returned object is not a tidygtfs object, you can use as_tidygtfs() after fixing the issue.

To fix, back up the zip file so you have an original copy:

cp MBTA_GTFS.zip MBTA_GTFS_original.zip

Now remove the offending file from the zip file

zip -d MBTA_GTFS.zip fare_products.txt

Now the file can be used as normal

I was able to produce many stringlines, after the fare_products.txt was removed
