Verified: December 2021 - TM:PE 11.5.2

This documentation is for TM:PE 11.5.2 and earlier.

If you are using TM:PE 11.6 or later, please refer to the new documentation: Speed Limits

Overview

Use this tool to set custom speed limits for roads and tracks.

Usage

This tool can be applied to:

  • Roads
  • Tram tracks
  • Monorail tracks
  • Metro tracks
  • Train tracks

Activate

Choose Speed Limits on the Toolbar:

Speed limit button

Button missing? Enable Speed Limits in Maintenance settings.

You can set a keyboard shortcut to activate the tool in the Keybinds settings.

Overlays

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

Speeds overlay

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.

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.

Customise

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

Speed palette

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

Note: When setting the speed of a tram track that's part of a road, both the road and the tram track will be set to the same speed.

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
  • 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.
  • 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

    You can also customise the icon style in General settings.

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.

FAQ

Does it affect framerate or cause lag?

No. The vanilla game already has to check road and rail speeds for each network segment, TM:PE just redirects those checks to a different list.

Some drivers ignore speed limits

The following vehicles can ignore speed limits:

  • Emergency vehicles when their sirens are active (responding to emergency)
  • Reckless Drivers; if Reckless driving enabled in Gameplay settings
  • Evacuation Buses; if Evacuation busses may ignore traffic rules enabled in Policies settings

Pedestrian and cycle paths don't get speed icons

Use these mods to control their speeds:
