Do I need the base map for Tokyo City?

Yes — this mod adds traffic/pedestrian data to an existing map, so you must install the base map first.

What this mod adds

Realistic AI traffic for TOKYO CITY (FREEROAM). The mod ships pre-tuned spawn density and lane data; the actual cars are driven live by the 2REAL Traffic Tool (2REAL App), which lets you adjust traffic density, spawn rules and behaviors while you drive.

You're adding a full traffic AI layer to Tokyo City. The lane definitions and spawn weights are baked in; the live behavior — gap rules, lane changes, indicators, density — is driven by the 2REAL Traffic Tool (2REAL App), which you can tune in real time from the in-game phone UI.

How it works with the 2REAL Traffic Tool (2REAL App)

The mod is data; the App is the engine. For Tokyo City, these are the App features that matter most:

Traffic Density — set spawn density per zone — Tokyo City works well with mid-to-high density on the highway and lower density on side roads.
Racemaker — build custom races on Tokyo City with start, finish and grid logic.
Performance Presets — if you run a busy car build, switch to a lighter preset — important on long open maps like Tokyo City.

Things people ask

Does this mod require the 2REAL Traffic Tool (2REAL App)?

Yes. The traffic and pedestrian behavior is driven by the 2REAL Traffic Tool (2REAL App). The mod ships the spline data; the App spawns and animates the AI at runtime.

Can I limit which cars spawn in the AI traffic?

Yes — use the Car List Editor in the App to control which cars are eligible to spawn. Useful if you want region-appropriate cars for Tokyo City.

Does this mod modify the base map's geometry?

No. The mod only adds spline and spawn data into the track's /data folder. The base map stays untouched, so you can disable the mod by removing the JSON files without affecting anything else.

Where do I get help if installation fails?

Join the 2REAL Discord — most install issues are resolved there in minutes. The install guide also covers the full setup from a clean Content Manager.

What's the recommended traffic density for Tokyo City?

Start with the App's default density and tune from there. On highway-heavy maps, mid-to-high density feels natural; on city maps, lower density with more police presence often feels more realistic. See Traffic Density for the full reference.
