1. A method of generating a horizon for use in an Advanced Driver Assistance System (ADAS) of a vehicle using stored digital map data, wherein the digital map data comprises a plurality of segments representative of roads of a road network, each segment being associated with data indicative of one or more attributes of the road represented by the segment, wherein one of the attributes is speed profile data that is indicative of an average speed of travel for traversing the road during one or more time periods, said method comprising:

  • determining data indicative of a relative probability that each of a plurality of possible outgoing paths associated with a decision point of the road network will be taken by the vehicle using at least the average speed for the time period appropriate for the time at which the horizon is generated from the speed profile data associated with the segments defining the respective outgoing paths, wherein the relative probability for each outgoing path is a respective portion of a specified total probability value for the decision point and the probabilities for each outgoing path sum to the specified total probability value;

    determining one or more predicted paths that the vehicle is expected to travel in the immediate future at the decision point using the data indicative of the relative probability;

    generating the horizon using the one or more predicted paths; and

    providing data associated with the generated horizon to one or more applications, the data associated with the generated horizon configured to be used by the one or more applications when controlling corresponding vehicle subsystems.
