Traffic Simulator is a Geometry Nodes setup that automatically generates roads and vehicle traffic along a drawn curve. It functions as an asset browser object that can be dragged directly into scenes.

The system includes adjustable settings for road generation, including curve resolution, lane counts, and bidirectional traffic configuration. Road materials can be customized using specific attributes for UVs, scale, and rotation. Traffic behavior is controlled through parameters for car frequency, initial vehicle count, speed, size, and orientation. Users can populate the simulation using a custom vehicle collection.
