  • determining at least one constant speed zone of the road network, a constant speed zone being a portion of the road network at which the vehicle can travel at a constant speed, said determination being based upon expected speeds of travel along the road network determined from positional data relating to the movements of a plurality of vehicles over time along the road network;

    determining a speed of the vehicle traversing the road network at a plurality of times during the journey;

    determining a value indicative of a consistency of the speed of the vehicle within the at least one constant speed zone, the determining comprising determining that the speed of the vehicle is not consistent between two locations in a given constant speed zone from the at least one constant speed zone when a difference between determined speeds at each of the two locations exceeds a threshold speed change; and

    presenting, to a user, based on the value indicative of the consistency of the speed of the vehicle within the at least one constant speed zone, advice indicating modifications of a driving style for driving the vehicle in order to improve an economy of driving the vehicle on the journey.
