Abstract
A method of determining routes for use in navigation is disclosed. The method includes steps of calculating a current route, calculating an alternative route and comparing the difference in times along each route with a minimum time difference. The minimum time difference is calculated using a dynamic threshold value that varies according to the difference in distances along the current route and the alternative route.
