The General Transit Feed Specification (GTFS) is a standard to represent transit systems (routes, schedules, stops, etc.). The gtfsr package makes it easy to analyze transit systems by: (1) providing an interface to APIs that provide GTFS feeds, (2) defining a standard data object for GTFS data, (3) validating multiple aspects of data/feed quality, (4) providing convenience functions for common data joins, (5) enabling useful visualizations, comparisons, and analyses of single or multiple transit systems. nA particularly interesting and challenging aspect of this project is determining how to assess data quality from various angles in a situation where it varies widely. Although the data formats in GTFS feeds are fairly straightforward, standardizing the way GTFS data is structured and validated in R has the potential to enable common R tools for sophisticated transit system analysis.
