METHOD OF CREATING MAP DATA COMPRISING TRANSIT TIMES FOR INTERSECTIONS
First Claim
1. A computerised method of creating map data from position data derived from the positions of at least one vehicle over a period of time, the map data comprising a plurality of navigable segments representing segments of a navigable route in the area covered by the map and the map data also comprising intersections between navigable segments representing intersections in the navigable route, the method comprising using a processing circuitry to perform the following:
- i. processing the position data;
ii. calculating from the processing of the position data a transit time or set of transit times for at least some of the intersections in the map data; and
iii. generating further map data, which for at least some of the intersections therein, contains the calculated transit time or set of transit times associated with the intersection for which the calculation was made.

Abstract
A computerised method is disclosed of creating map data from position data derived from the positions of at least one vehicle over a period of time, the map data including a plurality of navigable segments representing segments of a navigable route in the area covered by the map and the map data also including intersections between navigable segments representing intersections in the navigable route. In at least one embodiment, the method includes using a processing circuitry to perform the following: i. processing the position data; ii. calculating from the processing of the position data a transit time or set of transit times for at least some of the intersections in the map data; and iii generating further map data, which for at least some of the intersections therein, contains the calculated transit time or set of transit times associated with the intersection for which the calculation was made.

10. A machine arranged to create map data comprising a plurality of navigable segments, representing segments of a navigable route in the area covered by the map, and intersections, representing intersections between the navigable segments covered by the map, the machine comprising processing circuitry arranged to process position data derived from the positions of at least one vehicle over a period of time, the processing circuitry being programmed to:
-
i. process the position data; ii. calculate from the processing of the position data a transit time or set of transit times for at least some of the intersections in the map data; and iii. generate further map data, which for at least some of the intersections therein, contains the calculated transit time or set of transit times associated with the intersection for which the calculation was made. - View Dependent Claims (14)

12. A set of map parameters that in correlation with map data comprising a plurality of navigable segments, representing segments of a navigable route in the area covered by the map, and intersections, representing intersections between the navigable segments covered by the map that would allow an optimised estimation of the transit times based on clustering (or type of intersection).
