This video shows a day in the life of transit in the greater Washington, D.C. area. Rahul Nair, a civil engineering Ph.D candidate at the University of Maryland, used the Washington Metropolitan Area Transit Authority’s General Transit Feed Specification (GTFS) schedule and routing data to map out the movements of WMATA buses and subways over a 24-hour period.  This highlights what can be done when transit agencies make their GTFS schedule and routing data openly available, as Metro has done.

Nair used Processing, a Java-like language, to create this video.
