Traffic overlay. Look at the highway
All because of this.
Plz help. I can provide the save if you want.
You basically need more roads to move things around.
Everyone is using the same roads as there aren't enough options to take other roads.
Roads in the close up are too close together as well. Typically need a full block or more.

But I don't have enough room. Here take a look at the save. I used unlimited money because I'm planning to use this city for Youtube vids. So you'll need to use it as well. I also used TM: PE
Mark nailed it. More on/offramps wouldn't hurt.
Also, this is a great example of thinking that mods are going to fix things. They don't, they just make gameplay different.

Based on the second screenshot:
1. Everyone wants to take that one lane road to the south. One lane is not enough there to handle that traffic. Try to route traffic from the south west on a more direct way, preferably a completely different road.
2. Traffic from south west to north east crosses that mess. It should use a tunnel or overpass instead. And also that traffic doesn't flow. Why?
The road layout looks like you imported that from a real map. Maybe that was a bad idea. When you are still learning, easier layouts might be better.
And just saying: This is one of the situations where using TMPE does not help at all. The problem sits in front of the screen.
EDIT: As you have TMPE, you could try to use the function to reset all traffic. Then watch closely, where the first cars start queueing up. These are the points where you should start fixing. The junction on the screenshot could be a secondary issue, because it is blocked by cars not leaving that area.

That's a very cramped map. I see no easy way to fix this city as it is too chaotic.
You have railroad track running across roads and blocking traffic. elevate them, or put them underground.
You have insanely long, long streets. Things are on timers and this is making them time out and giving problems.
Mixing commerce and residential is making residential sick. Keep ALL noise polluting buildings away from residential.
You need dedicated highway entrances into industry to deal with traffic
You need commerce and industry next to each other so they can deliver freight more easily.
Too many one-way roads. You should have none or very little for special use.
Connect districts together with more roads.
Add on/off ramps along highways to get traffic in and out of your districts easier.
Maybe start a new map and embrace the grid. There is a reason pretty much every city uses them. Making tiny little island districts with one way in and out is choking your city. cims need to move around freely.
Try for more flat maps. Island maps are very hard until you learn the game better.

At a glance:
(1) Not enough entry & exit points to the city.
(2) Roads are too small to handle heavy traffic that will split up in different directions.
(3) Crossing are too close together.
I'll take a closer look at the save and tinker around after work.
edit: Allrighty. So...
(a) The road to your harbour and ore industry is a single lane industry road that funnels everybody into a single lane that then merges with wood industry traffic. There is no way it can handle all that.
(b) The area you show in your second screenshot merges that industry trafffic and the highway traffic and the city traffic with three almost adjacent crossings. A recipe for disaster. Us a roundabout instead.
(c) Your railroad creates crossing across the highway ramps. Either use bridges or tunnels to avoid that.
I'll make some edits to your save and upload the "fixed" version later.

Ok thanks to everybody. I usually have a very good layout for my cities, but this time I was in a hurry, so I randomly drew roads. I want to save the city, but I can't upgrade the roads since everyone (buildings) is so close to it. Also, I created that one-way road because the other roads are just cramped, so I tried to split the traffic, which somehow worked before. It cleared up the traffic on the bridge from the bigger island to the main island where most of my city is on. The last choice is just to start a new map, or just let it junk up.
Actually, that junction is blocked by oncoming cars, but the ones after it is also blocked by outgoing cars.
Allrighty, here is a save with a suggestion on how to tackle the worst issues.
Flow still isn't perfect, but I'd say good enough to be functional.
Key changes:
(1) Added various roundabouts to allow for proper traffic flow along the higher intensity roads.
(2) Replaced the northern Industrial Road with a two-way highway and added proper on/off ramps for the related industry sites
(3) Added a proper large connection between the central highway off ramp and the other city areas. Removed the center crossing cluster and put two roundabouts in its place.
(4) Connected various larger industry and high-traffic areas with their own roundabout on/offs.
(5) Enlarged the central road in the western city area and added some more vertical connector roads.
(6) Made sure that there is a proper on/off access point at the end of the western connector road.
(7) Removed some unnecssary connections in the center area to reduce the amount of crossings.
Didn't reconnect your public transport lines and moved quite a bit of stuff around, so take this more as a suggestion on how to handle traffic.
Some general rules you should follow to avoid traffic issues:
(a) Try to keep at least ~10 units of distance between crossings so traffic can flow properly.
(b) Use lane mathematics to make sure that the in & out roads are set up properly. Use short stretches of larger roads to create turn lanes at crossings, otherwise you can stick to 1 or 2 lane roads for general connections.
(c) Do not place utilities & large traffic buildings next to main connector roads. Build a crossing or roundabout and add a connector road there instead. Particularly important for cargo ports, airports and train hubs.
(d) Build bypass roads so traffic doesn't have to go through busy areas.
(e) Connect all city parts via pathways for pedestrians and bikes - CIMS wil travel quite far on their own if they can reach their target location by foot or bike.
(f) Use traffic manager to manually adjust lanes at crossings. Whenever you have a large road with smaller ones connected athe game tends to NOT create dedicated turning lanes. By manuall assigning one for left, one for ahead and one for right you will spread out traffic at the crossing, reducing the chances for traffic jams significantly.

Don't let oncoming cars block junctions. I see that you allow cars to enter junctions freely, which exacerbates the gridlock.
That TMPE-feature is for situations where the priority is clear (keeping traffic of the main road or roundabout flowing), not for every junction.
On that note: beware from using the lane connection feature excessively. It is easy to end up with networks which are impossible to navigate because one accidentally removed a crucial connection. In such cases, the colorful mess is hard to untangle. E.g. in the junction on the upper right coming from the right, the inner lane is forced to the right lane, but the right lane can move to the right and inner lanes, which makes no sense at all. An neither of those lanes connect to the left lane, which means that cars coming from the right cannot turn left on the next intersection(sure, they can do that on the first intersection, but I doubt that blocking the second intersection was planned)

Oh, yeah, one very basic thing that I forgot which warrants an addendum:
Disable traffic lights on junctions that have low traffic density (especially if most cars go one direction anyway).
They can hurt flow a lot and you don't even need any mods to fix that.

That's the one thing that disappoints me a little about the game is that traffic lights generally are useless and cause more problems than they solve. The TMPE mod's customizable traffic lights are better, but I still use them rarely. Yield signs often work much better (yet another useful feature curiously absent from the base game).
