A Highly Available GTFS-RT Positions System
Joshua Wong, Kin Tsang
We develop a system for real-time public transportation data, deciding to use the data standard GTFS-RT (GTFS Realtime), an open data format for public transit data. We give an ove…

Algorithmic Analysis of GTFS-RT vehicle position accuracy
Joshua Wong
This paper presents three novel algorithms for calculating geodesic intersections on an ellipsoid. These algorithms are applied in a case study analyzing real-time transit data in…
