Abstract
A method of generating flow data indicative of speeds of travel within a navigable network in an area covered by an electronic map is disclosed. The electronic map comprises a plurality of segments representing navigable elements of the navigable network. Live vehicle probe data is obtained indicative of the average speed of travel for the current time with respect to distance along a link, the link being predetermined by reference to the electronic map. The link is sectioned to provide a plurality of sections along the length thereof. The sectioning is carried out based on the data indicative of the current average speed of time along the link. Where a differential in the current average speed exceeds a threshold, a new section is created. Data is generated indicative of the location of the link together with data indicative of each determined section of the link, the data indicative of each determined section of the link being associated with data indicative of the average speed of travel for the current time for the section. The same process can be repeated using predicted flow data for a future time, but using a more stringent threshold, such that the link is divided into a smaller number of longer sections.
