Traffic jam problem. How to avoid it?

During my first few attempts with skylines I tried to use techniques I read about to control traffic flow like large one way roads, then roads beside the highway that are used as puffer zone, round goings for heavy traffic areas, .... but run into troubles there and not sure what I'm doing wrong. First the streets take up WAY more place than I had thought possible and second as in the screenshots below.......there are some perma traffic jam areas (the south has which is cut out has another one way that goes from right to left).
The elevated roads and the elevated circle are all highways.

The advise by Dr R Dizzle regarding optimizing that roundabout sounds good. But in addition to following these suggestions you should also try to reduce traffic overall.
- Make sure you have a good public transportation system with subways connecting all your districts and then bus lines transporting the people from the subway stations to the surrounding.
- Balance your industries so that you fulfill most needs yourself. This reduces traffic from import and export (specialized industries supply non-specialized industries and non-specialized industries supply commercial buildings). You can use the "Outside Connection" overview to check which buildings export or import.
- When you still need to import and export, make sure most of it leaves or enters your city by freight train or harbor.
