GTFS Accessibility Validator

There are a variety of fields and files in GTFS which provide accessibilty information to riders, and it is important for transit agencies to ensure that their published data includes this. The GTFS Accessibiltity Validator checks transit data in GTFS format for fields and files related to accessibility including wheelchair accessibility, text-to-speech phonetic spellings, color contast of route colors and station accessibility information.

Using the California Transit Data Guidelines published by Caltrans, BlinkTag created a web-based and programmatic accessibility validator. It allows anyone to upload a GTFS file and get a report on accessibility guidelines that pass and fail. The web-based version of the GTFS Accessibility Validator is available at validator.blinktag.com

The GTFS Accessibility Validator is also available as a command-line tool and NPM module that can be included within other projects.
