Linus Rosenqvist has an easy setup for a traffic simulation using POPs.

Another dive into proceduralism comes from a new tutorial by Linus Rosenqvist. The tutorial is a beginner-friendly and effortless setup to create a street and traffic simulation animation with Side FX Houdini. 

The traffic sim doesn’t rely on crowds or AI but instead uses a POP simulation with some post-simulation tweaks to get it just right. It’s not hero-shot worthy, but it’s an excellent trick for background elements easily.
