All Implemented Interfaces:

Incentive, VoluntaryIncentive

public class IncentiveCourtesy
extends Object
implements VoluntaryIncentive

Determines lane change desire for courtesy lane changes, which are performed to supply space for other drivers. In case drivers in adjacent lanes have desire to change to the current lane, the driver has desire to change to the other adjacent lane. The level of desire depends on lane change courtesy, as well as the distance of the leading vehicle for which desire exists. This desire exists for only a single vehicle, i.e. the one giving maximum desire. A negative desire may also result for leaders in the 2nd adjacent lane desiring to change to the 1st adjacent lane. By not changing to the 1st adjacent lane, room is reserved for the leader on the 2nd adjacent lane.
