Traffic Nodes
#############

For traffic simulations 2 nodes are available in the
`CrowdSim Node Editor`. The `Traffic Variable` to variate traffic
settings per agent. And the `Traffic` node to execute the traffic
simulation.

These nodes can be used together with the crowdsim nodes.
To create a simple traffic system you can add the next setup

See :ref:`adding-behavior` for more details on using the
`CrowdSim Node Editor` and its nodes.

Options:

  * **Traffic System**: The traffic system to let the agents drive on.
  * **Signals**: Whether turning and brake signals should be calculated.
    See :ref:`prepare-traffic-model` how to setup turning and braking animation
    for a model.
  * **Agents**: The set of agents that will be looked at when applying the
    traffic rules. Agents not added to this output will be ignored. When not
    connected at all, all agents in the scene will be used during the
    evaluation of the traffic rules.
