'''RoutePlanner ''' was a UK road navigation program written by [[ChaRleyTroniC]], and sold commercially by [[Sentinel Software]] and [[Radical Software]].

Using a database of the UK's motorways and A roads, RoutePlanner would generate the fastest or shortest route between any two places on request - as with the well-known PC program AutoRoute. This route would be drawn on a scrollable map of the UK, or shown in a printable itinerary.

The first version was very slow to calculate the longest routes (taking up to half an hour for Land's End to John O'Groats); UK, or shown in a subsequent revision brought this time down to a couple of minutesprintable itinerary.
