    shortDescription: Open source multi-modal trip planner focused on travel by
      scheduled and flexible public transportation combined with street routing.
    longDescription: 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.
