public LaneChange()

Method Detail

isChangingLane

public final boolean isChangingLane()

Return whether the GTU is changing lane.

Returns:

whether the GTU is changing lane

isChangingLeft

public final boolean isChangingLeft()

Return whether the GTU is changing left.

Returns:

whether the GTU is changing left

isChangingRight

public final boolean isChangingRight()

Return whether the GTU is changing right.

Returns:

whether the GTU is changing right

getTargetLane

public final RelativeLane getTargetLane()
                                 throws org.opentrafficsim.core.gtu.plan.operational.OperationalPlanException

Target lane of lane change.

Returns:

target lane of lane change

Throws:

org.opentrafficsim.core.gtu.plan.operational.OperationalPlanException - If no lane change is being performed.

setLaneChangeDuration

public final void setLaneChangeDuration(org.djunits.value.vdouble.scalar.Duration laneChangeDuration)

Sets the duration for a lane change. May be set during a lane change. Whenever the lane change progress exceeds the lane change duration, the lane change is finalized in the next time step.

Parameters:

laneChangeDuration - total lane change duration

updateAndGetFraction

final double updateAndGetFraction(org.djunits.value.vdouble.scalar.Duration timeStep,
                                  org.opentrafficsim.core.network.LateralDirectionality laneChangeDirection,
                                  LaneBasedGTU gtu)

Update the lane change and return the lateral fraction for the end of the coming time step. This method is for use by the operational plan builder. It adds the time step duration to the lane change progress. Lane changes are automatically initiated and finalized.

Parameters:

timeStep - coming time step duration

laneChangeDirection - direction of lane change

gtu - GTU

Returns:

lateral fraction for the end of the coming time step

toString

public final String toString()

Overrides:

toString in class Object
