How AI Traffic Works on Assetto Corsa Servers (SRP and No Hesi)

AI traffic on Assetto Corsa multiplayer servers, such as Shutoko Revival Project (SRP) and “no hesi” style highway servers, comes from AssettoServer, a custom server program that replaces the official Kunos server. It needs an AI spline (fast_lane.ai or fast_lane.aip) in the track’s ai folder, EnableAi: true in extra_cfg.yml and AI= slots in entry_list.ini. Your FREAKHOSTING server runs the official Kunos server, which has no AI traffic.

​

How to drive with AI traffic as a player

1. Install Content Manager and CSP.
2. Install the track and cars the traffic server lists, for example the Shutoko Revival Project track and the server’s car pack. Get them from the server’s own Discord or website.
3. Join the server from Content Manager. If you see “missing CSP features”, update CSP. See missing CSP features.

​

How an AI traffic server is set up

AssettoServer’s documentation describes these steps: AssettoServer also adds dynamic weather (CSP 0.1.76 or newer) and Steam authentication (CSP 0.1.75 or newer), and it has its own plugins and admin commands.

​

Can I run AI traffic on my FREAKHOSTING server?

Not on the Assetto Corsa game server as it is. It starts the official Kunos server (./acServer), and AssettoServer is a different program. Settings such as extra_cfg.yml and AI= do nothing on the Kunos server. What you can do:

• Ask us: open a ticket and tell us you want an AssettoServer traffic server. We’ll tell you what is possible.
• Use a VPS: AssettoServer can run on a VPS that you manage yourself, following the AssettoServer documentation.
• Race without traffic: for normal racing, the Kunos server with your own track and cars works as it is. See custom tracks.

Frequently asked questions

​

Why is there no traffic on my server?

The Kunos server doesn’t support AI cars online. Traffic servers run AssettoServer with an AI spline for the track.

​

What is an AI spline?

A file (fast_lane.ai or fast_lane.aip) that tells AI cars where to drive. It sits in the track’s ai folder. Not every mod track has one.

​

Do players need anything special for traffic servers?

Content Manager and CSP, plus the exact track and cars the server uses. Many traffic servers require a specific CSP version.

​

Is AssettoServer the same as Assetto Corsa Server Manager?

No. Server managers are tools that run the Kunos server for you. AssettoServer is a replacement server program with AI traffic.
