org.opentrafficsim.road.gtu.lane.tactical.util.ConflictUtil.ConflictPlans

All Implemented Interfaces:

Serializable

Enclosing class:

ConflictUtil

public static final class ConflictUtil.ConflictPlans
extends Object
implements Serializable

Holds the tactical plans of a driver considering conflicts. These are remembered for consistency. For instance, if the decision is made to yield as current deceleration suggests it's safe to do so, but the trajectory for stopping in front of the conflict results in deceleration slightly above what is considered safe deceleration, the plan should not be abandoned. Decelerations above what is considered safe deceleration may result due to numerical overshoot or other factor coming into play in car-following models. Many other examples exist where a driver sticks to a certain plan.

Method Detail

cleanPlans

void cleanPlans()

Clean any yield plan that was no longer kept active in the last evaluation of conflicts.

setArrivalTime

void setArrivalTime(AbstractHeadwayGTU gtu,
                    org.djunits.value.vdouble.scalar.Time time)

Sets the estimated arrival time of a GTU.

Parameters:

gtu - GTU

time - estimated arrival time

getArrivalTime

org.djunits.value.vdouble.scalar.Time getArrivalTime(AbstractHeadwayGTU gtu)

Returns the estimated arrival time of given GTU.

Parameters:

gtu - GTU

Returns:

estimated arrival time of given GTU

setStopPhaseApproach

void setStopPhaseApproach(HeadwayStopLine stopLine)

Sets the current phase to 'approach' for the given stop line.

Parameters:

stopLine - stop line

setStopPhaseYield

void setStopPhaseYield(HeadwayStopLine stopLine)

Sets the current phase to 'yield' for the given stop line.

Parameters:

stopLine - stop line

Throws:

RuntimeException - if the phase was not set to approach before

setStopPhaseRun

void setStopPhaseRun(HeadwayStopLine stopLine)

Sets the current phase to 'run' for the given stop line.

Parameters:

stopLine - stop line

Throws:

RuntimeException - if the phase was not set to approach before

isStopPhaseApproach

boolean isStopPhaseApproach(HeadwayStopLine stopLine)

Parameters:

stopLine - stop line
