Claim Text:
1. A computerised method of generating a route from an origin position to a destination position across an electronic map comprising a plurality of vectors representing segments of a navigable route in an area covered by the electronic map, the method comprising: obtaining delay data indicating delays on vectors within an area covered by the electronic map; calculating a first portion of a route, from an origin position toward the destination position, using a first routing method up to a predetermined threshold from the origin position, such that the first routing method uses the delay data so that the first portion of the route takes into account delays; calculating a second portion of the route beyond the predetermined threshold to the destination position using a second routing method to further calculate the route to the destination position, wherein the second routing method uses routing acceleration data which indicates vectors within the electronic map which form part of a lowest cost route according to a predetermined cost function; and providing instructions to navigate the route based on the calculated first and second portions of the route.
