Methodology used to calculate route information

AND Route identifies every type of road that could be covered during a planned journey (e.g. motorway, A-road, etc), and combines this with information on the typical average travelling speeds on these roads. The desirability of travelling on each road type is also assessed, and given a priority. AND Route uses both this priority data and the average speed information to determine the quickest route.

Speed preferences

Select "preferences" from the edit menu. Select the tab Road. In this tab you will be able to set your own road speeds and define which roads you prefer to drive on.
