A method of creating map data is disclosed, the map data including a plurality of navigable segments representing segments of a navigable route in the area covered by the map with each segment being arranged to have speed data associated therewith. In at least one embodiment, the method includes processing speed data relating to a plurality of the segments of the navigable route covered by the map to generate a set of generated speed profiles, with each generated speed profile within the set being an approximation to traffic speed along one or more of the segments of the navigable route and each speed profile varying with respect to time; and associating at least one speed profile from the set with a navigable segment within the map data.

Method of processing positioning data

A method of processing positioning data to create map data is disclosed, the map data including a plurality of navigable segments representing segments of a navigable route in the area covered by the map with each segment being arranged to have speed data associated therewith. In at least one embodiment, the method includes processing the speed data to categorise the speed data into a plurality of time periods for the navigable segment with which the speed data is associated; and averaging the speed data within each time period in order to generate a measured speed profile for the navigable segment.

A method of processing speed data is disclosed for use in the provision of enhanced map data including a plurality of navigable segments which together may define a navigable route in an area covered by a digital map. In at least one embodiment, the method includes (i) obtaining the speed data for at least one segment, the speed data including the measured speed of travel of a plurality of vehicles through the segment at different times; (ii) generating from the speed data for the at least one segment, data on at least one normal speed profile including an average speed of travel through the segment for a time recurring weekly; (iii) for at least one specified time, generating for the at least one segment data on at least one abnormal speed profile including an expected speed of travel through the segment during the specified time, the specified time being a time that does not occur weekly; and (iv) assigning to the at least one segment of the map data the corresponding normal speed profile and the abnormal speed profile for use by a navigation device in routing algorithms to determine a journey across the area.

Method and machine for generating map data and a method and navigation device for determining a route using map data

A method is disclosed, for processing positioning data to generate map data which includes a plurality of navigable segments representing segments of a navigable route in the area covered by the map, with each segment being arranged to have speed data associated therewith. In at least one embodiment, the method includes classifying the speed data associated with at least some, and generally each, navigable segment having speed data associated therewith into a category of a classification having a plurality of categories into which the speed data can be classified according to a parameter of a navigable segment with which the speed data is associated; generating a category average for each category within the classification; assessing at least some, and generally each, navigable segment within the map data to determine whether there is speed data associated therewith; and if there is no speed data associated with a navigable segment, using the category average, according to the parameter of the navigable segment being processed, as the speed data for the navigable segment being processed.
