This is a geometry nodes traffic simulator based on a curve, you draw a curve and you get a road with traffic

How to use it

• Add the object into your asset browser, 
• drag it into your scene when ever you want to use it

Settings:

road settings

Curve resolution: determines the subdivisions in the road

lanes: total number of lanes

Opposite lanes: how many lanes go the opposite direction

Road Material: the material for the road, this uses some attributes for the road, if you prefer to use your own shaders, make sure to use the same attributes for uvs, texture scale and rotation

Road size: width of the road and lanes

road padding: extra with for the road

Car settings

Collection: if you have your own cars, use them here

car_rate: how many flames pass before adding more cars i.e rate of 10, a car will be added every 10 frames

initial count: if you want to start with traffic on the road, how many do you want

Additional cars/f: this works with the car_rate, when cars are added, how many should be added

car size: size of the car

speed: speed"

orientation: rotation of the cars

start offset: where should the initial cars start on the road

road_texture settings

road_scale: texture scale

road_texture: chose the road texture

road_rotation: texture rotation

scale_x: texture scale on x

scale_y: texture scale on y
