Cross intersection vs pseudo roundabout?

[MarkShot9]

I noticed that cross intersections end up with traffic congestion. I also see it is possible to build a pseudo roundabout with four inputs instead. By pseudo roundabout I mean that traffic is not one way. But still I thought this might result in less contention.

Has anyone played around with this? I know this would be less space efficient and require more planning.

Also, I found a trick or exploit (in a discussion) were it is possible to make over/under passes instead of intersections. Although I have not tested this yet. When done, you know as cross walk lines are eliminated. I could see this as being useful avoiding the crossing of long haul roads avoiding merging until they enter the downtown dock feeder system. Thoughts?

Thanks!

the roundabouts work pretty well for me. when i get to a bigger country size (800 - 1200) traffic gets incredibly congested were i start to loose money. but i had a island with several roundabouts and it helped smooth out traffic.

In short, I've spent ubsurd amount amount of time messing with a huge amounts of ways to improve traffic, including building new land bridges and making roads around the previously impassable outer edge of the islands via teraforming.

Round-about work well. So do making double-roads, two roads next to each instead of just one, assuming you can get some of the traffic to go down the 2nd one. I sometimes add zig-zags to make a "local road" long than an "express road" in order to encourage cars to use them.

Perhaps the biggest simplest trick is to just add a right-hand turn bend on busy intersections. A roundabout is in many ways a four-way version of this with the middle removed.

I frequently max the island population out at 2000+, and then spend dozens of hours trying to improve the traffic further. It never gets easy until Modern Times when subways ("Metros") take the bulk of your traffic off the roads.

Try making a serpentine road all over the island that has no intersections. As long as there isn't too much space between roadways it works really well. Cars will make a U-turn as needed, and they will drop someone off on one side or the other. Eventually you'll have congestion areas but by that point metros fix it completely.
