1. A method of determining speed information for a plurality of road segments in map data, comprising:
receiving probe data relating to one or more road segments; determining an average speed for each of the one or more road segments from the probe data; determining a speed formula for determining an expected average speed for each of the one or more road segments based on the determined average speed from the probe data and one or more independent variables associated with each of the one or more road segments; and determining the speed information for the plurality of road segments according to the determined speed formula. |
