Class ConflictUtil.ConflictPlans

java.lang.Object
org.opentrafficsim.road.gtu.lane.tactical.util.ConflictUtil.ConflictPlans
All Implemented Interfaces:
Serializable, Blockable
Enclosing class:
ConflictUtil
public static final class ConflictUtil.ConflictPlans extends Object implements Blockable, 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.
