Abstract
A method of determining historical lane speed profiles for each of a plurality of individual lanes of a multi-lane road section is described. The plurality of individual lanes are lanes for the same given direction of travel. The method involves collecting vehicle probe data relating to the movement of individual vehicles on the road section for a specific time of day, and using the probe data to derive an aggregate speed profile for travel along each lane at the relevant time. The method may involve using the historical lane speed profiles to provide lane guidance instructions to the user of a navigation apparatus.
