Cities: Skylines II: The Ultimate Traffic Guide

What you need to know

You'll be designing your city's road infrastructure, considering road hierarchy, traffic flow, and intersection design. Roads have different functions and capacities, and you should avoid connecting roads that aren't in the right order. Understanding traffic flow is key to improving it, and you have options to make traffic go faster, increase vehicle density, or reduce the number of cars.

Step by step

1. Determine the road hierarchy in your city, with freeways having the highest speed and no intersections, and local roads having low speed and direct access to buildings.
2. Space out your intersections to maintain high speeds on freeways and arterial roads, with a minimum of 500 meters between intersections on freeways and 250 meters on arterials.
3. Use the in-game tools to build good-looking roads, including straight, simple curve, complex curve, continuous, grid, and replace modes.
4. Consider the rules of the highway, including lane mathematics, acceleration and braking lanes, and designing intersections wisely.

Tips

• Use turning lanes to prevent turning cars from slowing down other traffic.
• Add more lanes to increase the number of cars that can cross intersections when it's green.
• Remove intersections entirely if possible.
• Consider using protected left turns to prioritize left-turning traffic.
• Zone residential, commercial, and industrial areas carefully, considering factors like noise levels, pollution, and traffic flow.
• Place commercial areas in high-traffic areas to attract customers, and keep industrial areas away from residential areas to avoid pollution.
• Discourage car usage in office zones by providing public transport and limiting traffic throughput.
