gtfs-validator

A Java framework for GTFS validation and statistics.

How is this different than the Google-supported validator?

The Google TransitFeed-based validator is written in Python, and is quite slow on large feeds.

This validator uses the Onebusaway-GTFS library, written in Java and is far faster at processing large feeds.

Snapshots are available here

There are then multiple options for use:

Use the pre-built snapshot JAR. java -server -Xmx4g -Xms3g -jar gtfs-validator.jar yourGtfs.zip
Import the services provided and build your own validation.
Use the gtfs-validator-json and gtfs-validator-webapp according to the directions in those folders.

============== ValidatorMain

The ValidatorMain class logs a number of common GTFS errors to Standard Out on the console when run as a JAR. This includes:

Problems with route names
Bad shape coordinates
Unused stops
Duplicate stops
Missing stop coordinates
Missing stop times for trips
Stop times out of sequence
Duplicated trips (same times)
Overlapping trips when block_id is present
Missing shapes and shape coordinates
“Reversed” shapes with directions that do not agree with stop times.
Exhaustively going through the calendar and printing active service IDs and number of trips for that day.
Dates with no active service
