"Multiple direct routes diffuse traffic." I learned this a long time ago by a YouTuber named Lee Hawkins.

Thankfully the designers of this "game" seem to have gone out of business. :) But before they left, they provided everyone with a very easy to use tool for just such occasions as you point out. It's the ol' "D9" and it's very conveniently located at the bottom right hand corner of every game.

If you don't like the way your city's are turning out stop building them that way. You are pointing your nasty little finger at the wrong designer.

you say right

There is a very interesting phenomenon in this game: As the mayor, we plan how the citizens will pass through this intersection. At first, the citizens are very cooperative, but later on, they will only take one road. This will lead to a very serious situation that this road will be blocked , and then the entire city's traffic will come to a complete standstill. In response to what has been mentioned above, my suggestion is to make those citizens smarter, allowing them to follow the mayor's plan and ensure that every line is useful instead of just driving on one . This is a very good change for us beginners. I hope that as the designer of this game can change this phenomenon. Thanks!

If you see a single lane backup on your streets, this is by design. It is letting you know you are flooding your streets with traffic.

go to the front of the line and see where it is jammed up and try to give traffic behind you different ways to travel.

also, building in different directions. if you continue north, traffic will go north and start jamming up again.

but build with a purpose. There are high density building and low density building. if you build these in proportion, you can minimize traffic. 1 high density equals 4 low density.

Also, each job needs two workers, so build twice as many residential of the same density as the jobs.

For example, build two blocks of low density residential, and one block of low density commerce, and one generic industry and you should be fine. They will feed each other,

Just keep posting here and you should get a lot of help and things will start becoming clearer and clearer.

Posting screen shots can help.

Game developer do not read here and second the game is end of life. Only a few content creators are still adding some things. However no game changing mechanism.
If ever try and use TM: PE. Can help you with your traffic issues.
