Explain adaptive routing.

Adaptive routing defines the ability of a system, by which routes are characterised through their destination, to change the path that the route takes by the system in response to a modification in conditions. The adaptation is intended to permit as many routes as possible to remain valid (which have destinations which can be reached) in response to the change.

People utilizing a transport system can display adaptive routing. For illustration, if a local railway station is closed, people can alight from a train at other station and use another way, as a bus, only to reach their destination.
