OneBusAway

aid: onebusaway
name: OneBusAway
description: OneBusAway is an open-source real-time transit information platform managed by the Open Transit Software Foundation.
  It provides transit riders with real-time arrival predictions, service alerts, and schedule data for buses, trains, and
  other transit modes. The platform exposes a RESTful API that lets developers access agency information, stop data, route
  details, trip information, real-time arrivals and departures, vehicle positions, and service alerts. Authentication uses
  an API key passed as a query parameter. The reference deployment runs at api.pugetsound.onebusaway.org; many transit agencies
  host their own OneBusAway instances using the same API contract. Official SDKs are published for Go, Java, Kotlin, JavaScript/Node.js,
  Python, and Ruby, all generated from a shared OpenAPI 3.0 specification in the sdk-config repository.
