How to fix traffic?

[Paddy]

Hey guys I've only played 20 hours in city Skylines 1 and about 15 hours in this game so I'm pretty new. I was wondering what youtube series would you recommend for building a road system for newbies? I have traffic problems starting with just 10k population. I have buses and Taxi's which isn't helping much. Basically I created a fairly simple city system where I have a sprawling residential sector to the left. Commercial in the middle and industry to the right. The main road going through my higher density area is a 4 lane road which just keeps backing up at roundabouts and intersections.

when in doubt, roundabout.

A 4-lane road is pretty small if it's intended to be your main road. You can do things like starting as a larger road (6-lane) and then taper it down to a 4-lane after a junction. This will make one of the lanes on the 6-lane coming in be a dedicated turn lane to divert traffic. I haven't messed with roundabouts much, but the larger ones will handle more traffic.

I'm using large roundabouts but it's not helping. I'm wondering if I should start expanding the roads that goes through my city to an 8 lane? I probably shouldn't have built up my main high density areas right beside the 4 land main road through the city

Can you show a layout of your street and zones? Usually traffic problems are solved by adding alternative ways and one way streets through dense areas (a 4-lane one way is a big as the normal 4-lane road). I figures round abouts help only with moderate traffic. For high traffic I use lights and dedicated right turns (nearly as "ramps"). I manage the flow by restricting ways on intersections since left turns cause traffic jams.

Check the traffic flow and try to figure out where most of the people are going to. Then place parking lots where the traffic issue starts and make a bus line from that point to their target. I observed that parking lots act like a magnet for traffic, so you can re-route the traffic flow a bit. If a bus line is available to their target, the people might switch to bus lines.

Note: I still have to figure out how the traffic system works, so there's a chance that my theory doesn't work, but this is an approach I'll try out myself when playing CS2 the next time. I think the new traffic AI system must be taken into account for such situations.
For the roundabout, it doesn't help on high traffic because they tend to get blocked easily. I already created a bug report for it.

Follow road hierarchy. EG have a main highway through the city which has the outside connection. Then for each of your districts have a collector road that collects all the traffic from that area and puts it on the highway via junctions/intersections, and then branching off the collector you can have your local roads, roads with the actual zoning on them.

add more then one entry way into the city seemed to help me
