Shortcuts

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

Selection:

Click junction - select the junction
- Any previously selected junction will be deselected
- You can now use basic applicators
Right-click anywhere - deselect current junction
- If no junction selected, it will exit the Junction Restrictions tool as if you pressed Esc
Esc - exit Junction Restrictions tool
- This returns focus to the Toolbar and enables its Adjust Roads mode.

Basic applicators:

These change junction restrictions for the selected junction. Set city-wide defaults in Policies settings.

Click a restriction icon - toggle it on/off

Bulk applicators:

See High Priority Roads

Camera / Overlays:

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

Overlays

While the tool is active, summary overlays are displayed on the map. To reduce clutter, these overlays only show where changes have been made:

(todo: image)

To see the restrictions for more distant roads and rails, scroll the camera towards them. Depending on camera position, you might need to zoom in a little.

You can set the transparency of overlays in General settings.

When the tool is deactivated overlays will be removed. You can enable a persistent summary overlay, which is visible whenever the Toolbar is visible, in Overlays settings.

Refresh

When you make changes, only vehicles spawned after that point will be aware of them.

To make existing vehicles aware of changes, enable Customisations come in to effect immediately in General settings. This may add some momentary lag on old potato computers or on big cities.

Alternatively, you can use the Clear Traffic tool to remove all existing traffic from the map, leaving only newly spawned traffic that is aware of your changes.

FAQ

Does it affect frame rate or cause lag?

Not usually. However, if you start disabling pedestrian crossings, it can cause more work for the pathfinder which may cause performance issues on larger cities.

I clicked on a rail junction but no icons appear?

Currently, only Level Crossings (a junction where rail tracks intersect a road) are supported.
