Constructor Detail

RoadBasedTrackModel

public RoadBasedTrackModel(RoadBasedIntersection intersection)

Basic class constructor. Takes an lane-based intersection and construct a track model for the intersection.

Parameters:

intersection - a lane-based intersection.

Method Detail

getIntersection

public RoadBasedIntersection getIntersection()

Get the intersection managed by this track model

Specified by:

getIntersection in interface TrackModel

Returns:

the intersection managed by this track model

getSortedDepartureLanes

public List<Lane> getSortedDepartureLanes(Lane arrivalLane,
                                 Road departure)

Given an arrival Lane and a departure Road, get an ordered List of Lanes that represents the Lanes from highest to lowest priority based on distance from the arrival Lane.

Specified by:

getSortedDepartureLanes in interface TrackModel

Parameters:

arrivalLane - the Lane in which the vehicle is arriving

departure - the Road by which the vehicle is departing

Returns:

the ordered List of Lanes, by priority, into which the vehicle should try to turn

trajectoriesConflict

public boolean trajectoriesConflict(int l11,
                           int l12,
                           int l21,
                           int l22)

Determine whether two trajectories overlap. Errs on the side of caution.

Specified by:

trajectoriesConflict in interface TrackModel

Parameters:

l11 - the ID number of the entry lane for the first trajectory

l12 - the ID number of the exit lane for the first trajectory

l21 - the ID number of the entry lane for the second trajectory

l22 - the ID number of the exit lane for the second trajectory

Returns:

whether the trajectories specified conflict

traversalDistance

public double traversalDistance(Road arrival,
                       Road departure)

Get the distance from the entry of the given Road, to the departure of the other given Road.

Specified by:

traversalDistance in interface TrackModel

Parameters:

arrival - the arrival Road

departure - the departure Road

Returns:

the distance from the entry of the arrival Road to the exit of the departure Road

traversalDistance

public double traversalDistance(Lane arrival,
                       Lane departure)

Get the distance from the entry of the given Lane, to the departure of the other given Lane, if traveling along segments through their point of intersection.

Specified by:

traversalDistance in interface TrackModel

Parameters:

arrival - the arrival Lane

departure - the departure Lane

Returns:

the distance from the entry of the arrival Lane to the exit of the departure Lane through their intersection

traversalDistance

public double traversalDistance(int arrivalID,
                       int departureID)

Get the distance from the entry of the Lane with the first given ID, to the departure of the Lane with the other given ID, if traveling along segments through their point of intersection.

Specified by:

traversalDistance in interface TrackModel

Parameters:

arrivalID - the ID number of the arrival Lane

departureID - the ID number of the departure Lane

Returns:

the distance from the entry of the arrival Lane to the exit of the departure Lane through their intersection
