Plan journeys across transit, cycling, walking, and mobility services.
OpenTripPlanner builds multimodal journey-planning services combining scheduled public transport with walking, cycling and mobility services. Its Java server constructs a transport network from GTFS and OpenStreetMap data, applies real-time updates and alerts, and exposes GraphQL APIs. Web and mobile clients can request itineraries that reflect service changes, while operators host the server on a Java-capable platform.
