A Java framework for GTFS validation and statistics.

The Google TransitFeed-based validator is written in Python, and is quite slow on large feeds. I also find the code rather hard to understand. While it supports extensions, few have extended it.

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

This project originated at Conveyal. This fork includes a number of updates and improvements, namely:

• Requiring Java 8
• Updated dependencies to currently supported versions
• Minor bug fixes and light refactoring
• More testing
• Continuous Integration via Travis, and
• A number of additional validations

There are then multiple options for use:

1. Use the JAR provided in the releases. java -jar gtfs-validator.jar yourGtfs.zip

2. Import the services provided and build your own validation.

3. 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
