Connections, transfers and interchanging

Most journey planners allow transfer times for a transport interchange to be specified to some degree – usually as default exchange times to use either for all interchanges of a particular MODE, or at a specific station. Some allow individual transfer times between platforms to be stated. The NeTEx model allows a set of TRANSFER DURATIONs for journey planning to be exchanged with successive levels of precision as to scope (general, a specific station, a specific pair of stops), all inheriting from the TRANSFER concept.
