Class IncentiveSpeed

  • All Implemented Interfaces:
    Incentive, VoluntaryIncentive

    public class IncentiveSpeed
    extends Object
    implements VoluntaryIncentive
    Determines lane change desire for speed, where the slowest vehicle in the current and adjacent lanes are assessed. The larger the speed differences between these vehicles, the larger the desire. Negative speed differences result in negative lane change desire. Only vehicles within a limited anticipation range are considered. The considered speed difference with an adjacent lane is reduced as the slowest leader in the adjacent lane is further ahead. The desire for speed is reduced as acceleration is larger, preventing over-assertive lane changes as acceleration out of congestion in the adjacent lane has progressed more.
