Compute the acceleration and lane change.

Specified by:

computeLaneChangeAndAcceleration in interface DirectedLaneChangeModel

Parameters:

gtu - GTU; the GTU for which the acceleration and lane change is computed

direction - the direction of the lane we want to change to

sameLaneTraffic - Collection<HeadwayGTU>; the set of information about observable GTUs in the current lane (can not be null and may include the gtu)

otherLaneTraffic - Collection<HeadwayGTU>; the set of information about observable GTUs in the adjacent lane where GTUs should drive in the absence of other traffic (must be null if there is no such lane)

maxDistance - the maximum distance that the current GTU can drive, e.g. due to a lane drop

speedLimit - Speed; the local speed limit

otherLaneRouteIncentive - Acceleration; route incentive to merge to the adjacent lane where GTUs should drive in the absence of other traffic

laneChangeThreshold - Acceleration; threshold that prevents lane changes that have very little benefit merge to overtake other traffic

laneChangeTime - time spent to overtake

Returns:

LaneMovementStep; the result of the lane change and GTU following model

Throws:

org.opentrafficsim.core.gtu.GTUException - when the position of the GTU on the lane(s) cannot be determined

getName

public final String getName()

Return the name of this GTU following model.

Specified by:

getName in interface DirectedLaneChangeModel

Returns:

String; just the name of the GTU following model

getLongName

public final String getLongName()

Return complete textual information about this instantiation of this GTU following model.

Specified by:

getLongName in interface DirectedLaneChangeModel

Returns:

String; the name and parameter values of the GTU following model

toString

public final String toString()

Overrides:

toString in class Object

getPerception

public final LanePerception getPerception()

Specified by:

getPerception in interface DirectedLaneChangeModel

Returns:

the perception.
