If the traffic is still stuck, you might try using parallel lanes. For example:

The middle lane is for going straight, the parallel lanes for going other directions.

Tips & Tricks
Don't use too many curves,
Don't use interchanges too close to each other,
Try building new highways,
Don't use too many roads.

For now have fun with the interchanges!

I think you meant for this to be in the Tips and Tricks section lol. This section is for plug-in tutorials. Nice tutorial though.

Now I realise this is only for plug ins lol Can someone move this to tips & tricks

Added some interchanges

Suggest interchanges!

Do you guys want a building video?

I don't have much time but I will try

This is how Malaysia Interchanges look like I will make it later

It's not difficult at all, I just did it and it only lasts 1:30 minutes
Price: Médium
Traffic level: Very light
Complexity: Medium
Land required: a little high

A cloverleaf intersection in jakarta was Freaking busy

This interchange actually works quite well:

The one commander uses works well!

It is diamond interchange. It is good, but you can make it even smaller

I don't understand it very well.
Could you explain it to me?

Highway in grey with bridges has two directional green ramps attaching to both sides of the alley in dark blue. You can just use expressway for the greenroad also.

From the highway bridge on top, a car would turn right, reach the bottom, turn left to turn left and go under the bridge or (see alley second chance up) turn around or turn right to turn left to turn right .

From the alley (first chance) a car would turn left to turn right and up then turn right or straight to turn left to turn around.

From the alley (second chance) a car would turn left to turn right and up then turn right to turn left or straight to turn left to turn around.

Bold indicates final or in case of a highway turnaround, another trip through.
