Determining lane speed information for each of a plurality of individual lanes of a multi-lane road section that is a lane for a predetermined direction of travel;
Using the lane speed information to determine when to provide a lane selection command to a user of the navigation device;
Equipped with a,
The lane selection command includes (i) a lane change command, (ii) a lane selection command required to follow a predetermined route to the destination, (iii) an exit command, (iv) one or more users At least one of: a lane selection command that allows an event affecting the lane of the vehicle to pass through; and (v) a lane selection command that is determined to provide the quickest route through at least a portion of the road segment. wherein the Rukoto Oh. The method of claim 1, wherein the lane speed information is determined at least in part using real-time data. 3. The method of claim 1 or 2, comprising using vehicle probe data to determine the lane speed information for each lane. 4. The method of claim 1, 2 or 3, wherein the lane speed information for each lane includes a lane speed profile for each lane. Using lane speed information in the form of lane profiles for the two lanes to determine a speed difference profile between two different lanes of a plurality of lanes, and using the speed difference profile to determine the timing 5. The method according to any one of claims 1 to 4, further comprising: The lane selection command is a lane change command and the method includes at least a current lane and lane speed information associated with the lane that the user is trying to change to determine the timing, and preferably a lane for any intermediate lane. 6. A method according to any one of the preceding claims, comprising using velocity information. The lane speed information associated with at least a portion of the road segment ahead of the user's current location to determine the timing of providing the lane selection instruction. 7.
