Priority Signs

Overview

Use priority signs to define who has right of way at junctions of roads, tracks, and level crossings.

This allows you to improve traffic flow on a busy route, at the expense of increased congestion/disruption to the other routes at the junction. For more information, see Priority Routes.

Usage

Choose Priority Signs on the Toolbar:

Priority Signs tool

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

Applicators

Select a Junction to customize. You'll see a spot over each road entering the junction:

Icon

Purpose

Empty spot

Placeholder for a priority sign.



Click to cycle through the signs (Priority > Yield > Stop > back to Priority...)

Priority

Priority - traffic on this route has right of way when entering the junction.

Yield

Yield / Give Way - traffic must slow down and only enter the junction if there are no priority vehicles waiting to enter.

Stop

Stop - similar to Yield, but traffic must always come to a complete stop even if the junction is clear.

(todo: icon)

Reset - clears all the priority signs at the junction.

Shortcuts

The following shortcuts are applicable when the Priority Signs tool is active...

Selection:

  • Click a junction - select the junction

    • Any previously selected junction will be deselected

    • You can now apply basic applicators

  • Esc or Right mouse click - exit Priority Signs tool

Applicators:

  • Click a priority sign icon - cycle through priority signs (Priority > Yield > Stop > back to Priority...)

Overlays:

  • Shift - highlight route the mouse is over

    • It will try going "straight ahead" at junctions

    • On one-way roads, it will try and find roundabouts / semi-roundabouts

    • If no suitable ongoing route is found, the route will terminate at that junction

  • Control - show persistent summary overlays for Junction Restrictions and Speed Limits

Bulk applicators:

  • Shift+Click a segment - apply priority signs to junctions along the route

    • Repeat the shortcut to cycle through various configurations of priority signs

  • Ctrl+Click a junction - apply High Priority Roads policies to that junction

    • Use the shortcut a second time to remove the customizations

  • Ctrl+Shift+Click a segment - depends on the route:

    • If route is a roundabout (loop of one-way roads) or semi-roundabout:

    • If not a roundabout:

    • Use the shortcut a second time to remove the customizations

Camera:

  • Mouse wheel - zoom in or out

    • If you zoom out too far, icons may disappear

  • PageDown - underground view

  • PageUp - overground view

Overlays

While the tool is active, summary overlays show which junctions have been customized:

Pic priority signs overlay

To see customizations for more distant roads and tracks, move 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.

Icon Themes

Depending on your language settings (see General Settings in Settings), TM:PE can show localized signs.

Currently available localisations:

  • American (en/us) - these signs are shown by default should localize signs not be available

  • Chinese (zh)

  • English (gb) - pending Issue #1251

  • Welsh (cy) - pending Issue #1251

Refresh

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

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

Alternatively, use the Clear Traffic tool to delete all existing vehicles; it puts less strain on CPU, so it's faster than the option above if you have old computer or big city.

Notes

When traffic from multiple roads is entering a junction, there can be confusion over who gets to enter the junction first. On low-volume junctions, it's usually not a problem. But as junctions get busier, that uncertainty starts to cause traffic jams.

To overcome this issue, there is a general priority rule even when no priority signs are used. It depends on which side of the road traffic drives on:

  • Vehicles drive on Left? Traffic approaching from the right has priority.

  • Vehicles drive on the Right? Traffic approaching from the left has priority.

However, these basic traffic rules aren't always sufficient. For example, consider this junction:

(todo: image)

If there's vehicles waiting to enter from each road at the same time, who gets to go first? If Jim Street is a busier route than Bob Street, how do we ensure that Jim gets priority over Bob? Priority signs remove the confusion:

(todo: image)

Now, traffic can flow much more freely along Jim Street because it knows it has priority. Although Bob Street has to wait a bit longer, we've improved overall traffic flow for the majority of vehicles in the area.

FAQ

Does this affect frame rate or cause lag?

I Control + Clicked but nothing happened

What happens if Yield or Stop traffic waits too long?

I altered my roads but customizations didn't update

Some vehicles seem to ignore the rules!
