Draw roads. Run the simulation. Fix the traffic.

Draw roads and bridges, connect growing districts, and watch your city come alive. Design efficient interchanges and prevent your city from becoming Jammed.

Draw Your Road Network

Place districts and draw one-way roads and bridges by hand. Every connection changes how traffic moves through your city.

Watch Traffic Come Alive
