Abstract
Lane speed profiles are determined for each of a plurality of individual lanes of a multi-lane road section. The plurality of individual lanes are lanes for a given direction of travel. The lane speed profiles are determined using real-time vehicle probe data. The speed profiles are used to determine a timing for provide an instruction to a user of a navigation apparatus to change lane. The timing may be determined to provide a quickest route through at least a part of the road section, to increase the time available for the user to perform the lane change, or to enable a user to pass an incident affecting a lane most quickly.
