1. A method of processing data relating to an electronic map, the map comprising a plurality of segments representing navigable segments in the area covered by the map, the method comprising using a processing apparatus to generate segment data and comprising the steps of:

  • collecting historic travel data for the segment;

    defining a jam condition for the segment, such that where the jam condition is satisfied the segment is classified as jammed and otherwise as not jammed, the jam condition being a jam threshold speed;

    generating a jam probability for the segment according to the historic travel data and the jam threshold speed, the jam probability indicating the likelihood of a jam on the segment;

    generating a jam speed for the segment using the historic travel data, the jam speed being indicative of the speed on the segment when the segment is considered jammed; and

    associating the jam probability and the jam speed with the segment in the electronic map.
