Free GTFS API for Denver Regional Transportation District (RTD) transit data

Overview

The Transport for Denver API provides GTFS (General Transit Feed Specification) data for Denver’s Regional Transportation District (RTD). It includes static feeds (routes, stops, schedules, fare information) and real-time GTFS-RT data (vehicle positions, trip updates, service alerts). Static data uses CSV formats compliant with GTFS standards, while real-time data uses Protocol Buffers. Use cases include building transit trip planners, real-time arrival trackers, route mapping apps, and integrating Denver transit data into navigation platforms for commuters and visitors.
