Creating, Exploring, and Manipulating GTFS Files

Creating, exploring, analyzing, and manipulating General Transit Feed Specification (GTFS) files, which represent public transportation schedules and geographic data. The package allows users to filter data by routes, trips, stops, service dates, and time, generate spatial visualizations, and perform detailed analyses of transit networks, including headway, dwell times, route frequencies, service span, scheduled vehicle-hours, and trip duration. Methods follow common public transport planning and operation concepts described in Ceder (2007, ISBN:978-0-7506-6166-6), Vuchic (2005, ISBN:978-0-471-63265-8), Vuchic (2007, ISBN:978-0-471-75823-5), Cascetta (2009) , and Gentile and Noekel (2016) .
