                                                        throws GTUException,
                                                               ParameterException

Compute the acceleration and lane change.

Specified by:

computeLaneChangeAndAcceleration in interface LaneChangeModel

Parameters:

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

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

rightLaneTraffic - Collection<Headway>; the set of 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)

leftLaneTraffic - Collection<Headway>; the set of observable GTUs in the adjacent lane into which GTUs should merge to overtake other traffic (must be null if there is no such lane)

speedLimit - Speed; the local speed limit

preferredLaneRouteIncentive - 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

nonPreferredLaneRouteIncentive - Acceleration; route incentive to merge to the adjacent lane into which GTUs should merge to overtake other traffic

Returns:

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

Throws:

GTUException - when the speed of the GTU can not be determined

ParameterException - in case of a parameter problem.

getName

public final String getName()

Return the name of this GTU following model.

Specified by:

getName in interface LaneChangeModel

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 LaneChangeModel

Returns:

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

toString

public final String toString()

Overrides:

toString in class Object
