GENERATING ROUTES TO OPTIMISE TRAFFIC FLOW

A method is disclosed for determining a route in an area covered by an electronic map, the map comprising a plurality of segments representing navigable segments of a navigable network in the area covered by the electronic map. The method involves generating a plurality of routes through the navigable network between a first location and a second location, determining a relative traffic flow value for each of the routes using data indicative of a relative current capacity of segments of the navigable network, and selecting a given one of the routes from the plurality of routes for use in navigating between the first location and the second location. The probability of a given one of the plurality of routes being selected is based on the determined relative flow value for the route.
