Field Detail

LANE_ADD_EVENT

public static final EventType LANE_ADD_EVENT

The (regular, not timed) event type for pub/sub indicating the addition of a Lane to a CrossSectionLink.
Payload: Object[] { String networkId, String linkId, String LaneId, Lane lane, int laneNumber }
TODO work in a different way with lane numbers to align to standard lane numbering.

LANE_REMOVE_EVENT

public static final EventType LANE_REMOVE_EVENT

The (regular, not timed) event type for pub/sub indicating the removal of a Lane from a CrossSectionLink.
Payload: Object[] { String networkId, String linkId, String LaneId }
TODO allow for the removal of a Lane; currently this is not possible.

Constructor Detail

CrossSectionLink

public CrossSectionLink(Network network,
                        String id,
                        Node startNode,
                        Node endNode,
                        LinkType linkType,
                        OTSLine3D designLine,
                        SimulatorInterface.TimeDoubleUnit simulator,
                        LaneKeepingPolicy laneKeepingPolicy)
                 throws NetworkException

Construction of a cross section link.

Parameters:

network - Network; the network

id - String; the link id.

startNode - OTSNode; the start node (directional).

endNode - OTSNode; the end node (directional).

linkType - LinkType; the link type

designLine - OTSLine3D; the design line of the Link

simulator - the simulator on which events can be scheduled

laneKeepingPolicy - LaneKeepingPolicy; the policy to generally keep left, keep right, or keep lane

Throws:

NetworkException - if link already exists in the network, if name of the link is not unique, or if the start node or the end node of the link are not registered in the network.

CrossSectionLink

protected CrossSectionLink(Network newNetwork,
                           SimulatorInterface.TimeDoubleUnit newSimulator,
                           boolean animation,
                           CrossSectionLink link)
                    throws NetworkException

Clone a CrossSectionLink for a new network.

Parameters:

newNetwork - the new network to which the clone belongs

newSimulator - the new simulator for this network

animation - whether to (re)create animation or not

link - the link to clone from

Throws:

NetworkException - if link already exists in the network, if name of the link is not unique, or if the start node or the end node of the link are not registered in the network.

Method Detail

addCrossSectionElement

protected final void addCrossSectionElement(CrossSectionElement cse)

Add a cross section element at the end of the list.
Note: LEFT is seen as a positive lateral direction, RIGHT as a negative lateral direction.

Parameters:

cse - CrossSectionElement; the cross section element to add.

getCrossSectionElementList

public final List<CrossSectionElement> getCrossSectionElementList()

Retrieve a safe copy of the cross section element list.

Returns:

List<CrossSectionElement>; the cross section element list.

getLaneKeepingPolicy

public final LaneKeepingPolicy getLaneKeepingPolicy()

Retrieve the lane keeping policy.

Returns:

LaneKeepingPolicy; the lane keeping policy on this CrossSectionLink

getCrossSectionElement

public final CrossSectionElement getCrossSectionElement(String id)

Find a cross section element with a specified id.

Parameters:

id - String; the id to search for

Returns:

CrossSectionElement; the cross section element with the given id, or null if not found

getLanes

public final List<Lane> getLanes()

Return a safe copy of the list of lanes of this CrossSectionLink.

Returns:

List<Lane>; the list of lanes.

getPriority

Returns:

priority.

setPriority

public final void setPriority(CrossSectionLink.Priority priority)

Parameters:
