The standard,

parsed properly
GTFS (General Transit Feed Specification) is the standard transit agencies use worldwide to publish schedule and live vehicle data — the same format behind Google Maps and most trip planners. This project parses it directly: no database, no caching layer, just a C++ library scanning the raw GTFS Schedule .txt tables and GTFS Realtime .pb protobuf feeds and answering queries straight off them.
