CitiesSkylinesMods/TMPE ? reverse-engineered prompt

Build me a Cities: Skylines mod called Traffic Manager, President Edition that gives players more control over road and rail traffic in their city.

I want a clean in game tool that lets me manage traffic rules, road behavior, and rail flow without having to dig through complicated menus. Make it feel polished, easy to use, and built for the latest version of Cities: Skylines. If there are existing docs or current game modding details that would help, look them up online and use them.

Please set it up so it can be installed and updated like a normal mod, with a clear settings screen, sensible defaults, and stable behavior during gameplay. If there are any common traffic bugs or routing issues you can handle, include fixes or workarounds where possible. Also make sure it is easy to test, easy to maintain, and that the important parts are documented so other people can understand how to use it.
