How to add Vehicles traffic

hi guys i it s possible to create cars trafic wich i already have cars but i need o add them to a scene

Hello, I created this effect by simply drawing out splines for the traffic to flow along. Then, using fairly simple collision detection, move each car along the curve. If it detects something ahead, slow down etc… You can see my attempt here: UE4 TRAFFIC WIP 01 - YouTube Hope this helps!
