Abstract:In recent years, the standardization of transit schedule information has yielded a dramatic increase in the accessibility of computerized transit schedules and given rise to real-time service schedules. Two such real-time service schedules are the General Transit Feed Specification Real-time (GTFS-R) and the Service Interface for Real-time Information (SIRI). Due to system/vendor limitations, the Metropolitan Transportation Authority (MTA) uses GTFS-R for its real-time subway schedule and SIRI for its real-time bus schedule. In order to promote development of applications using real-time scheduling data, MTA needed a single real-time scheduling format. The purpose of this project is to create an Application Programming Interface (API) that is capable of converting GTFS-R into SIRI. The GTFS-R to SIRI real-time data feed will unify their data streams to provide developers and travelers with more complete access to real-time transit data in the largest mass transit market in the country. Furthermore, in keeping with the spirit of Open Data, Open Source, AVAIL developed a configurable server for use with the converter. By uploading a General Transit Feed Specification (GTFS) zip file or providing a URL pointing to a GTFS feed source, and specifying a URL for the GTFS-R feed, this server can be easily used to convert GTFS-R data to SIRI by any transit agency or researcher throughout the world.
