Cities: Skylines II

Description

Successor to TM:PE for Cities Skylines II

The goal of the project is to bring more tools to the game that could help users manage traffic, well known from CS1 TM:PE mod and new ones.

Included features

• Lane Connector Tool - no need to describe it for users familiar with TM:PE in CS1, but for new players, it's a tool which allows for changing lane connections at intersection to any that suits your use case. Since the mod cannot read the user's mind, in certain conditions it may require revisiting the modified intersection to add or change connections. More details below.

• Priorities Tool - a tool that allows for changing lane priority at intersection to any that suits your use case. Since the mod cannot read the user's mind, in certain conditions it may require revisiting the modified intersection to reapply the change.

Usage

Ctrl+R enable Lane Connector Tool or simply click on the button in top left corner, then select any intersection.

Change lane connections by selecting source and target lane circles.

For more advanced setups:

• hold Alt to change the mode to unsafe connection (dashed) - doesn't work for track connections

• hold Ctrl for track-only connection,

• hold Shift for road-only connection

• hold Ctrl+Shift for shared-only connection (e.g.: Car+Tram)

Known issues and limitations (in the current version)

• No support at intersections with the roundabout upgrade, custom lane connections has to be reset first to apply the upgrade

• No support for vanilla forbidden direction upgrades (tooltips with more information is available in game)

• No support for managing bidirectional lane connections (e.g.: two-way single train/tram track connections)

• Intersection with custom Lane Connections will not generate lane connections when modified by e.g.: adding new intersecting road - connections need to be created manually or simply reset

Custom Lane Connections may be automatically removed (leaving lanes not connected!) in following conditions:

• when the network composition has changed e.g.: "small two-way road" was replaced with asymmetric 2+1 variant

• road direction has changed with help of replace tool

• tram track upgrade has been applied or removed

Issues and limitations above are possible to solve, but they require extensive effort which would delay the release of the mod, so I decided to reduce the initial scope of compatibility features. I hope to improve them later, with your help.

Compatibility with other modifications

• Automatic data migration from Traffic Lights Enhancement's Lane Direction tool into Traffic's Lane Connections (a message dialog will appear with migration results when loading a savegame)

• Tested with Extended Road Upgrades, no issues found.

• Selecting a road (or all instances) with Road Builder mod will reset Traffic's custom priorities and lane connections

Saving

The mod is storing the data inside the savegame file, but thanks to how CS II is handling missing mods and assets, savegames will load correctly but the changes applied by the mod will reset once a road/rail network update is triggered, resetting them to the defaults.

Editor

The mod was not tested thoroughly in the map editor, but is expected to save the Lane connector and Priorities tool settings data into the map file which should later load successfully when a new game is created from it. Opinions/tests greatly appreciated.

Plans

Multilanguage translation support is handled via Crowdin, link in the mod description. In case of critical issues, small bugs fixes or tweaks they will be released more frequently.

Feedback, Features Ideas, Support

You can contact me on TM:PE or Cities: Skylines Modding discord and PDX forum in the comment section of the mod, but for easier management, for larger feature requests or anything that requires more discussion, I'd prefer GitHub's Issues or Discussions

Changelog

0.2.12.1 - Released 2026-02-05

• fixed a rare issue causing the game to crash (on load or in-game) after loading/creating a bike connection between a bus lane and a non-bus lane.

• fixed a rare issue corrupting custom connections data if a source segment was split

• fixed a rare issue corrupting custom connections data if a source segment was replaced by merging short segments (the game may replace two short segments with one longer one if it determines the node connecting them is no longer needed)

• fixed an issue with the Reset to vanilla action when data contains broken custom lane connections (the previously mentioned corrupt lane connection data)
