This project was funded by the National Institute for Transportation and Communities (NITC) under grant number NITC-RR-1062. The PI would like to acknowledge the Google Summer of Code program, which funded Nipuna Gunathilake’s work on a very early version of the opensource GTFS-realtime Validator software tool. Thanks to Mohan Gandhi Achchakkagari and Surya Vamshi Kandukoori for their software development work on the GTFS-realtime Validator during this project, and Surya Vamshi Kandukoori for his contributions to the open-source Transit Feed Quality Calculator tool as well as his efforts in collecting, analyzing, and visualizing errors and warnings found in feeds.

In the last few years, a real-time counterpart to GTFS, GTFS-realtime , has begun to emerge, with agencies sharing their real-time data in this format. Previously, real-time transit information had only been shared in proprietary formats specific to each vendor or agency. GTFS-realtime offers the opportunity for application developers to create a mobile app that can function across a large number of cities and agencies, and for practitioners and researchers to be able to easily study and compare actual system performance across different transit systems using the same tools, without the overhead of manually transforming data into a consistent format. Having real-time transit data available in a common format is a key pillar for real-time multimodal information systems.
