org.opentrafficsim.core.gtu.plan.operational.OperationalPlan

org.opentrafficsim.road.gtu.lane.plan.operational.LaneBasedOperationalPlan

All Implemented Interfaces:

Serializable

public class LaneBasedOperationalPlan
extends OperationalPlan

An operational plan with some extra information about the lanes and lane changes so this information does not have to be recalculated multiple times. Furthermore, it is quite expensive to check whether a lane change is part of the oprtational plan based on geographical data.

Constructor Detail

LaneBasedOperationalPlan

public LaneBasedOperationalPlan(LaneBasedGTU gtu,
                                OTSLine3D path,
                                Time startTime,
                                Speed startSpeed,
                                List<OperationalPlan.Segment> operationalPlanSegmentList,
                                boolean deviative)
                         throws OperationalPlanException

Construct an operational plan with or without a lane change.

Parameters:

gtu - LaneBasedGTU; the GTU for debugging purposes

path - OTSLine3D; the path to follow from a certain time till a certain time. The path should have <i>at least</i> the length

startTime - Time; the absolute start time when we start executing the path

startSpeed - Speed; the GTU speed when we start executing the path

operationalPlanSegmentList - List<Segment>; the segments that make up the path with an acceleration, constant speed or deceleration profile

deviative - boolean; whether the path is not along lane center lines

Throws:

OperationalPlanException - when the path is too short for the operation

LaneBasedOperationalPlan

public LaneBasedOperationalPlan(LaneBasedGTU gtu,
                                DirectedPoint waitPoint,
                                Time startTime,
                                Duration duration,
                                boolean deviative)
                         throws OperationalPlanException

Build a plan where the GTU will wait for a certain time. Of course no lane change takes place.

Parameters:

gtu - LaneBasedGTU; the GTU for debugging purposes

waitPoint - DirectedPoint; the point at which the GTU will wait

startTime - Time; the current time or a time in the future when the plan should start

duration - Duration; the waiting time

deviative - boolean; whether the path is not along lane center lines

Throws:

OperationalPlanException - when construction of a waiting path fails

Method Detail

isDeviative

public final boolean isDeviative()

Check if we deviate from the center line.

Returns:

whether this maneuver involves deviation from the center line.

getTotalLengthAlongLane

public final Length getTotalLengthAlongLane(LaneBasedGTU gtu)
                                     throws GTUException

Returns the total length along the reference lane that the GTU travels. In case of a deviative plan this involves projection of the actual path to the lane center lines.

Parameters:

gtu - LaneBasedGTU; GTU

Returns:

Length; total length along the path

Throws:

GTUException - if the GTU has not reference position

getDistanceAlongLane

public final Length getDistanceAlongLane(LaneBasedGTU gtu,
                                         DirectedPoint point)
                                  throws GTUException

Returns the distance along the reference lane that the GTU travels from the current location up to the point.

Parameters:

gtu - LaneBasedGTU; GTU

point - DirectedPoint; point where the GTU is or will be

Returns:

Length; total length along the path

Throws:

GTUException - if the GTU has not reference position

toString

public final String toString()

Overrides:
