1. A method, said method comprising:

  • obtaining or holding available at least one speed profile for at least one selected link of a travel network, wherein said at least one speed profile represents a plurality of speeds for a plurality of subsequent segments of said selected link;

    smoothing said at least one speed profile for said at least one selected link in a first smoothing step by;

    determining whether said at least one speed profile represents one or more speeds that are associated with an acceleration above a predetermined acceleration threshold or a deceleration below a predetermined deceleration threshold;

    for each speed that is determined to be associated with an acceleration above said acceleration threshold or a deceleration below said deceleration threshold, determining a respective adapted speed for replacing said respective speed at least partially based on speeds for one or more adjacent segments of said respective segment; and

    causing at least partial control of a vehicle according to the at least one speed profile after smoothing.
