OpenTripPlanner is an open-source, server-side Java application for multi-modal trip planning, computing itineraries that combine public transit with walking, biking, bike share, and ride hailing. It builds routing networks from GTFS and OpenStreetMap data, applies real-time service updates, and exposes GraphQL APIs for web and mobile clients.

Use cases

  • plan public transit trips with walking and biking connections
  • build a journey planner API from GTFS and OpenStreetMap data
  • power a transit navigation mobile app with real-time disruptions
  • run a self-hosted multimodal route planner for a city or region
  • analyze transportation network accessibility
  • combine bike share and ride hailing with scheduled transit in routing

When to choose

  • you need open-source transit trip planning with real-time GTFS updates
  • you want routing built from open standard data (GTFS, OpenStreetMap)
  • you need a GraphQL journey-planning API for web or mobile clients
  • you're deploying regional or national passenger information services

When to avoid

  • you only need driving directions or car-only navigation
  • you need a turnkey hosted service rather than a self-run Java server
  • your data isn't in GTFS or OpenStreetMap-compatible formats
