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. Set of yield plans in case of having priority. Such plans are remembered to get 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

isYieldPlan

boolean isYieldPlan(HeadwayConflict conflict,
                    AbstractHeadwayGTU gtu)

Returns whether a plan exists for yielding at the conflict for the given conflict GTU.

Parameters:

conflict - conflict

gtu - conflicting GTU

Returns:

whether a plan exists for yielding at the conflict for the given conflict GTU

setYieldPlan

void setYieldPlan(HeadwayConflict conflict,
                  AbstractHeadwayGTU gtu)

Sets or maintains the plan to yield at the conflict for the given conflict RSU.

Parameters:

conflict - conflict to yield at

gtu - conflicting GTU

cleanYieldPlans

void cleanYieldPlans()

Clears 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)
