Speed Limits (11.5.2 and earlier)

Activate

Choose Speed Limits on the Toolbar:

Button missing? Enable Speed Limits in Maintenance Settings in Settings.

You can set a keyboard shortcut to activate the tool in the Key Bindings in Settings.

Overlays

While the tool is active, detailed overlays show the current speeds of all roads and tracks on the map:

To see speeds for more distant roads and tracks, scroll the camera towards them. Depending on camera position, you might need to zoom in a little. You can set the Overlay Transparency in General Settings in 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 in Settings.

customize

When the tool is active, you'll see a palette containing available speed options:

To change speeds, copy them from the palette and paste them on to icons on the map:

• Copy: Click button on panel

• Paste: Click icon on map

Shortcuts

The following shortcuts are applicable when the Speed Limits tool is active...

Camera / Overlays:

• Mouse wheel - zoom in or out

  • If you zoom out too far, icons may disappear

• PageDown - underground view

  • This also activates a simplified version of the Traffic Info View!

• PageUp - overground view

Selection:

• Ctrl (or Cmd on Macs) - toggle between direction and lane-wise mode

• Esc - exit Speed Limits tool

Basic applicators:

• Click a sign - change speed (to whatever you selected on speed palette)

• Shift + Click a sign - change speed and apply that change along the route

Extras

The palette has some other options:

• Default speed limits: Allows you to set default speed limits for roads and rails.

  See old documentation for current implementation

• Show lane-wise speed limits: When enabled, you can set the speed for each lane individually.

• Display speed limits as MPH instead of km/h: When enabled, speeds will be shown in miles per hour

Refresh

Traffic will automatically adapt to changed speed limits, usually after a few seconds but could be longer on big cities or potato computers.

Why the delay? To simulate so many vehicles, the game uses a trick called "Leader Vehicles"; when there's a group of vehicles driving the same route, all the computationally expensive calculations of the leader are reused by the followers. So if the leader already drove on the segment(s) at the old speeds, the followers will do the same.

Deactivate

Press Esc or switch to any other tool when you're finished.
