Abstract

A method is disclosed for generating routes in an area covered by an electronic map. The map comprises a plurality of segments representing navigable segments of a navigable network in the area covered by the electronic map. A main route from an origin to a destination is generated through the network in a manner which favors segments which are segments of a predefined sub-network. When the user commences travel, the method involves identifying a first decision point along the main route being travelled that is a decision point of the sub-network. An alternative route is generated between the decision point and the destination, in a method involving favoring segments of the sub-network, and in which the outgoing segment of the main route being travelled to the first decision point is blocked.
