Vehicle Restrictions

Overview

Use this tool to separate vehicle categories in to different lanes on your roads and train tracks.

Usage

Choose Vehicle Restrictions on the Toolbar:

Applicators

Click a road or rail segment to edit the vehicle restrictions for each lane:

Clicking the icons toggle between allowed vs. discouraged states, for example:

Allowed Car	Discouraged Car

Icons

Roads:

Icon	Vehicles
	Cars - passenger cars and motorbikes
	Buses - passenger, sightseeing and evacuation buses
	Taxis
	Trucks - all types of industry trucks and vans
	Services - all services including emergency services
	Emergencies - Vehicles responding to emergencies (active sirens)

Trains:

Icon	Vehicles
	Passenger Trains - both local and regional
	Cargo Trains - both local and regional

Vehicle Routing

Vehicles calculate their route before starting their journey. As a result, when you change restrictions, only vehicles spawned after that point will be aware of your changes.

To force existing vehicles to calculate new routes when you make changes, enable Apply AI changes right away in General Settings in Settings.

Shortcuts

The following shortcuts are applicable when the Vehicle Restrictions tool is active...

Selection:

Click a segment of road/rail - choose segment to customize
- Any previously selected segment will be deselected
Right-click anywhere - deselect current segment
- If no segment selected: Exit the Vehicle Restrictions tool as if you pressed Esc
Esc - exit Vehicle Restrictions tool
- Returns focus to the Toolbar and enables its Adjust Roads mode.

Basic applicators:

Click a vehicle icon - toggle the restriction on/off
Shift+Click a vehicle icon - toggle restriction on/off and apply that change along the route

Camera / Overlays:

Mouse wheel - zoom in or out
- If you zoom out too far, icons may disappear
PageDown - underground view
- This activates a simplified version of the Traffic Info View
PageUp - overground view

Overlays

While the tool is active, icons summarize vehicle restrictions on nearby roads/tracks:

To see icons for distant roads/tracks, move the camera towards them. Overlay transparency can be set in General Settings in Settings.

When the tool is deactivated overlays will be removed. A persistent overlay, which summarizes vehicle restrictions whenever the Toolbar is visible, can be enabled in Overlays in Settings.

Notes

This tool is designed to provide fine-tuning of traffic restrictions, for example:

Prevent trucks driving through residential areas
Make passenger trains choose a different rail track
Stop trucks cargo using inner lane of highways
Prevent cars and trucks from using bus lanes
It's better to use 🚧 Bus Lane Restrictions to achieve this

Remember to provide alternate routes for vehicles, otherwise they might not be able to reach their destination.

Reckless Drivers ignore vehicle restrictions
Emergency vehicles, when responding to an emergency (red/blue lights flashing), also ignore vehicle restrictions

How it works

Restriction = pathfinding penalty
Vehicle Restriction Aggression sets penalty magnitude
Penalties are cumulative for a route
Pathfinder tries to avoid incurring penalties
If penalty is too high, and no alternative routes, the route is cancelled
- This prevents vehicle spawning (or, if already spawned, the vehicle will despawn)

Service Coverage

If you want to limit coverage of service buildings, use these mods instead:

Service Radius Adjuster or Customize It: Extended!:
- Control the travel distance a building will service
Real Time:
- Lets you control where cims shop (e.g. local to where they live/work), etc.
