The anticipation speed in the current and adjacent lanes are compared. The 8 * larger the difference, the larger the lane change desire. For negative differences, negative desire results. 9 * Anticipation speed involves the the most critical vehicle considered to be in a lane. Vehicles are more critical if 10 * their speed is lower, and if they are closer. The set of vehicles considered to be on a lane includes drivers on 11 * adjacent lanes of the considered lane, with a lane change desire towards the considered lane above a certain 12 * certain threshold. If such vehicles have low speeds (i.e. vehicle accelerating to merge), this may result in a 13 * courtesy lane change, or in not changing lane out of courtesy from the 2nd lane of the mainline. Vehicle on the 14 * current lane of the driver, are not considered on adjacent lanes. This would maintain a large speed difference 15 * between the lanes where all drivers do not change lane as they consider leading vehicles to be on the adjacent lane, 16 * lowering the anticipation speed on the adjacent lane. The desire for speed is reduced as acceleration is larger, 17 * preventing over-assertive lane changes as acceleration out of congestion in the adjacent lane has progressed more.<br> 18 * <br> 19 * <b>Note:</b> This incentive includes speed, and a form of courtesy. It should therefore not be combined with 20 * incentives solely for speed, or solely for courtesy. 21 * @author Wouter Schakel 22 */ 23 public class IncentiveSpeedWithCourtesy implements VoluntaryIncentive { 24 25 /** {@inheritDoc} */ 26 @Override 27 public Desire determineDesire(final LaneBasedGTU gtu, final LanePerception perception, Desire mandatory) { 28 return new Desire(0, 0); 29 } 30 31 }
