Open source multi-modal trip planner focused on travel by scheduled and flexible public transportation combined with street routing.
OpenTripPlanner (OTP) is an open source multi-modal trip planner, focused on travel by scheduled public transportation in combination with walking, cycling, driving, and mobility services including bike share and ride hailing. Its server component runs on any platform with a Java virtual machine (including Linux, Mac, and Windows). It exposes GraphQL APIs that can be accessed by various clients including open source Javascript components and native mobile applications. It builds its representation of the transportation network from open data in open standard file formats (primarily NeTEx, Siri, GTFS, GBFS and OpenStreetMap). It applies real-time updates and alerts with immediate visibility to clients, finding itineraries that account for disruptions and service changes.
