    "definition": "A place where several transport modes or routes meet so that passengers or freight can transfer between them, such as a major railway station with bus and metro connections, an airport with rail links, a port with rail and road terminals or a logistics centre; hubs concentrate flows, enable interchange and are planned as nodes of networks.",
