public class Lane
extends CrossSectionElement
implements Serializable

The Lane is the CrossSectionElement of a CrossSectionLink on which GTUs can drive. The Lane stores several important properties, such as the successor lane(s), predecessor lane(s), and adjacent lane(s), all separated per GTU type. It can, for instance, be that a truck is not allowed to move into an adjacent lane, while a car is allowed to do so. Furthermore, the lane contains sensors that can be triggered by passing GTUs. The Lane class also contains methods to determine to trigger the sensors at exactly calculated and scheduled times, given the movement of the GTUs.
Finally, the Lane stores the GTUs on the lane, and contains several access methods to determine successor and predecessor GTUs, as well as methods to add a GTU to a lane (either at the start or in the middle when changing lanes), and remove a GTU from the lane (either at the end, or in the middle when changing onto another lane).

nextLanes

public final Map<Lane,org.opentrafficsim.core.gtu.GTUDirectionality> nextLanes(org.opentrafficsim.core.gtu.GTUType gtuType)

NextLanes returns the successor lane(s) in the design line direction, if any exist.
The next lane(s) are cached, as it is too expensive to make the calculation every time. There are several possibilities: (1) Returning an empty set when there is no successor lane in the design direction or there is no longitudinal transfer possible to a successor lane in the design direction. (2) Returning a set with just one lane if the lateral position of the successor lane matches the lateral position of this lane (based on an overlap of the lateral positions of the two joining lanes of more than a certain percentage). (3) Multiple lanes in case the Node where the underlying Link for this Lane has multiple "outgoing" Links, and there are multiple lanes that match the lateral position of this lane.
The next lanes can differ per GTU type. For instance, a lane where cars and buses are allowed can have a next lane where only buses are allowed, forcing the cars to leave that lane.

Parameters:

gtuType - the GTU type for which we return the next lanes.

Returns:

set of Lanes following this lane for the given GTU type.

prevLanes

public final Map<Lane,org.opentrafficsim.core.gtu.GTUDirectionality> prevLanes(org.opentrafficsim.core.gtu.GTUType gtuType)

PrevLanes returns the predecessor lane(s) relative to the design line direction, if any exist.
The previous lane(s) are cached, as it is too expensive to make the calculation every time. There are several possibilities: (1) Returning an empty set when there is no predecessor lane relative to the design direction or there is no longitudinal transfer possible to a predecessor lane relative to the design direction. (2) Returning a set with just one lane if the lateral position of the predecessor lane matches the lateral position of this lane (based on an overlap of the lateral positions of the two joining lanes of more than a certain percentage). (3) Multiple lanes in case the Node where the underlying Link for this Lane has multiple "incoming" Links, and there are multiple lanes that match the lateral position of this lane.
The previous lanes can differ per GTU type. For instance, a lane where cars and buses are allowed can be preceded by a lane where only buses are allowed.

Parameters:

gtuType - the GTU type for which we return the next lanes.

Returns:

set of Lanes following this lane for the given GTU type.

accessibleAdjacentLanes

public final Set<Lane> accessibleAdjacentLanes(org.opentrafficsim.core.network.LateralDirectionality lateralDirection,
                                               org.opentrafficsim.core.gtu.GTUType gtuType)

Determine the set of lanes to the left or to the right of this lane, which are accessible from this lane, or an empty set if no lane could be found. The method takes the LongitidinalDirectionality of the lane into account. In other words, if we drive in the DIR_PLUS direction and look for a lane on the LEFT, and there is a lane but the Directionality of that lane is not DIR_PLUS or DIR_BOTH, it will not be included.
A lane is called adjacent to another lane if the lateral edges are not more than a delta distance apart. This means that a lane that overlaps with another lane is not returned as an adjacent lane.
Note: LEFT and RIGHT are seen from the direction of the GTU, in its forward driving direction.

Parameters:

lateralDirection - LEFT or RIGHT.

gtuType - the type of GTU for which to return the adjacent lanes.

Returns:

the set of lanes that are accessible, or null if there is no lane that is accessible with a matching driving direction.

getSpeedLimit

public final org.djunits.value.vdouble.scalar.Speed getSpeedLimit(org.opentrafficsim.core.gtu.GTUType gtuType)
                                                           throws org.opentrafficsim.core.network.NetworkException

Get the speed limit of this lane, which can differ per GTU type. E.g., cars might be allowed to drive 120 km/h and trucks 90 km/h.

Parameters:

gtuType - the GTU type to provide the speed limit for

Returns:

the speedLimit.

Throws:

org.opentrafficsim.core.network.NetworkException - on network inconsistency

setSpeedLimit

public final void setSpeedLimit(org.opentrafficsim.core.gtu.GTUType gtuType,
                                org.djunits.value.vdouble.scalar.Speed speedLimit)

Set the speed limit of this lane, which can differ per GTU type. Cars might be allowed to drive 120 km/h and trucks 90 km/h. If the speed limit is the same for all GTU types, GTUType.ALL will be used. This means that the settings can be used additive, or subtractive.
In additive use, do not set the speed limit for GTUType.ALL. Now, one by one, the allowed maximum speeds for each of the GTU Types have be added. Do this when there are few GTU types or the speed limits per TU type are very different.
In subtractive use, set the speed limit for GTUType.ALL to the most common one. Override the speed limit for certain GTUTypes to a different value. An example is a lane on a highway where all vehicles, except truck (CAR, BUS, MOTORCYCLE, etc.), can drive 120 km/h, but trucks are allowed only 90 km/h. In that case, set the speed limit for GTUType.ALL to 120 km/h, and for TRUCK to 90 km/h.

Parameters:

gtuType - the GTU type to provide the speed limit for

speedLimit - the speed limit for this gtu type

removeSpeedLimit

public final void removeSpeedLimit(org.opentrafficsim.core.gtu.GTUType gtuType)

Remove the set speed limit for a GTUType. If the speed limit for GTUType.ALL will be removed, there will not be a 'default' speed limit anymore. If the speed limit for a certain GTUType is removed, its speed limit will default to the speed limit of GTUType.ALL.
Note: if no speed limit is known for a GTUType, getSpeedLimit will throw a NetworkException when the speed limit is retrieved for that GTUType.

Parameters:

gtuType - the GTU type to provide the speed limit for

getLaneType

public final LaneType getLaneType()

Returns:

laneType.

getDirectionality

public final org.opentrafficsim.core.network.LongitudinalDirectionality getDirectionality(org.opentrafficsim.core.gtu.GTUType gtuType)

The direction in which vehicles can drive, i.e., in direction of geometry, reverse, or both. This can differ per GTU type. In an overtake lane, cars might overtake and trucks not. It might be that the lane (e.g., a street in a city) is FORWARD (from start node of the link to end node of the link) for the GTU type CAR, but BOTH for the GTU type BICYCLE (i.e., bicycles can also go in the other direction, opposite to the drawing direction of the Link). If the directionality for a GTUType is set to NONE, this means that the given GTUType cannot use the Lane. If a Directionality is set for GTUType.ALL, the getDirectionality will default to these settings when there is no specific entry for a given directionality. This means that the settings can be used additive, or restrictive.
In additive use, set the directionality for GTUType.ALL to NONE, or do not set the directionality for GTUType.ALL. Now, one by one, the allowed directionalities can be added. An example is a lane on a highway, which we only open for CAR, TRUCK and BUS.
In restrictive use, set the directionality for GTUType.ALL to BOTH, FORWARD, or BACKWARD. Override the directionality for certain GTUTypes to a more restrictive access, e.g. to NONE. An example is a lane that is open for all road users, except TRUCK.

Parameters:

gtuType - the GTU type to provide the directionality for

Returns:

the directionality.

addDirectionality

public void addDirectionality(org.opentrafficsim.core.gtu.GTUType gtuType,
                              org.opentrafficsim.core.network.LongitudinalDirectionality directionality)
                       throws org.opentrafficsim.core.network.NetworkException

This method sets the directionality of the lane for a GTU type. It might be that the driving direction in the lane is FORWARD (from start node of the link to end node of the link) for the GTU type CAR, but BOTH for the GTU type BICYCLE (i.e., bicycles can also go in the other direction; we see this on some city streets). If the directionality for a GTUType is set to NONE, this means that the given GTUType cannot use the Lane. If a Directionality is set for GTUType.ALL, the getDirectionality will default to these settings when there is no specific entry for a given directionality. This means that the settings can be used additive, or restrictive.
In additive use, set the directionality for GTUType.ALL to NONE, or do not set the directionality for GTUType.ALL. Now, one by one, the allowed directionalities can be added. An example is a lane on a highway, which we only open for CAR, TRUCK and BUS.
In restrictive use, set the directionality for GTUType.ALL to BOTH, FORWARD, or BACKWARD. Override the directionality for certain GTUTypes to a more restrictive access, e.g. to NONE. An example is a lane that is open for all road users, except TRUCK.

Parameters:

gtuType - the GTU type to set the directionality for.

directionality - the longitudinal directionality of the link (FORWARD, BACKWARD, BOTH or NONE) for the given GTU type.

Throws:

org.opentrafficsim.core.network.NetworkException - when the lane directionality for the given GTUType is inconsistent with the Link directionality to which the lane belongs.

removeDirectionality

public void removeDirectionality(org.opentrafficsim.core.gtu.GTUType gtuType)

This method removes an earlier provided directionality of the lane for a given GTU type, e.g. for maintenance of the lane. After removing, the directionality for the GTU will fall back to the provided directionality for GTUType.ALL (if present). Thereby removing a directionality is different from setting the directionality to NONE.

Parameters:

gtuType - the GTU type to remove the directionality for on this lane.

getGtuList

public final List<LaneBasedGTU> getGtuList()

Returns:

gtuList.
