Traffic Node

Traffic node is a set of traffic node entities that are connected to other traffic node entities by a :ref:`path <path>

Settings

Cached

Traffic light crossroad : the crossroad to which the node belongs.

Traffic light handler : traffic light that the traffic node is linked (TrafficLightHandler).

Lane Data

Lanes : right side lanes (to connect TrafficNodes within a RoadSegment).

External lanes : left side lanes (to connect nodes in external RoadSegments) (additonal info).

Settings

Lane count : number of lanes.

Lane width : lane width.

Chance to spawn : chance of the vehicle spawning in the node.

Weight : weight of the node for route selection by traffic.

Custom achieve distance : custom distance to achieve a node (if 0 value default value will be taken).

Capacity : capacity of the nodes (used for parking, bus station, etc…).

Light type:

• Right : right-hand lanes have traffic lights.

• Left : left-hand lanes have traffic lights.

• Right and left : right and left lanes have traffic lights.

Traffic node type:

• Default

• Parking : node where cars are parked (read more parking states).

• Traffic public stop : node where public traffic stops to pick up passengers.

• Destroy vehicle : node where the vehicle entity is destroyed (useful for nodes outside the map).

• Traffic area : TrafficArea node.

• Idle : node where the vehicle is idling.

Is one way : all lanes are one-way traffic lanes (more info).

Is end of one way : node ends one-way traffic for this RoadSegment (more info).

Lock path auto creation : on/off prevent auto path creation (more info).

Auto path is created : auto path is created (more info).

Buttons

Connect : node will try to connect to other nodes if no external paths are created yet.

Force connect : node will try to connect to other nodes whether it is connected now or not (except Lock path auto creation option is enabled).

Resize : resize collider of node.

OneWay Node Info

Oneway node description example:

Node example key features:

• Node 1:

  • Is one way [enabled]

  • Source path is in the : [Lanes]

  • External Lanes [Always empty]

• Node 2:

  • Is one way [enabled]

  • Is end one way [enabled]

  • Source path is in the : [External Lanes]

  • Lanes [Always empty]

Direction Connection Info

Rightside Lanes

Rightside lanes (default lanes) connect TrafficNodes within a RoadSegment.

Rightside lanes example.

Leftside Lanes

Leftside lanes (external lanes) connect TrafficNodes in external RoadSegments (external connection example).

Leftside lanes example.

Warning

Intersecting External paths should be replaced by a separate segment to bake the intersection of the paths.

Node Rotation

Direction of each TrafficNode must be opposite to the center of the segment

Example description:

• The arrow represents the forward rotation of the node.

• Purple arrows the direction of the outer nodes of the segment.

• Blue arrows the direction of the internal segment oneway nodes.

Auto-path Connection

• To quickly create connections between RoadSegments on the same line, the Auto-Path connection is used.

• If the segments are not on the same line you should to create another Custom straight road segment or Custom segment between them and do the same connection.

• You can also manually create paths between segments using the PathCreator tool.

How To Use

• To activate auto-connection paths for all nodes you can in RoadParent by pressing Connect button.

• Each time you create a new RoadSegment or move an existing RoadSegment, press Reset and press Connect in RoadParent, then Bake Path Data (baking info).

Note

• To prevent auto-path connection for the selected TrafficNode enable Lock path auto creation in the settings of the node.

• Each TrafficNode has a box collider whose is size calculated based on the number of lanes, their width, and the type of lanes (one-way or not).

• Make sure that the direction of the node is set correctly.

CullState Info

States

• Culled : entity not available for spawning.

• CloseToCamera : entity available for spawn.

• InVisionOfCamera : entity available for spawn only during the initial scene start.
