Can someone explain me roundabouts (no mods)

['Cypek <kz.random> mH <33333333]

So I just started playing the game and I have a headeache while doing roundabouts. I have watched some youtube tutorials but they have installed mods and those are for experienced players. When I try to do perfect circle roundabout its very very hard since I don't see grid and angles. I need to count my mouse moves to do it. So i made one after some effort, its perfect but not as a circle, its more square one. I made a screenshot https://steamcommunity.com/sharedfiles/filedetails/?id=1692350286
Can someone help me how to make them an easy way and perfect?

For a bare minimum you'll at least need this...

... because it let's you see clearly the angles of roards you're building.

But for a no hassle, instant method, you'd need this one...

While that will work, IMO it doesn't build the skill and teach how to make a roundabout. Once you know how in vanilla you can whip them out in a couple seconds, no mods needed. What helps me is to make a + with my roads, connect each point with the curved road option, then delete the inner +. Also note once it is built as a circle you need to have your branch off points be the nodes (blue circles). If you try to connect it on a part that is not a node it will distort your roundabout and make it lop sided.

does it generate money? xD

It helps alleviate traffic congestion in intersections that have moderately heavy traffic. The downside of the roundabouts is that they take up space and they only displace (relocate) the traffic congestion. In real life they are a headache for drivers.

Thank you for help.

The roundabout builder is bad for me, I can't use it. Whenever I want to build one I can't match it to the crossroads(like the grid is different) or when I make one everything feels broken, like grass is there, road is isnt properly build etc.

Some roundabouts are quite small and not even take up much space, examples include the Welcome Rotonda in Manila-Quezon City border, or in a small residental suburb with a pretty small roundabout that takes up only two in-game units/square grids (very common on planned residental communities here in the Philippines).

First, I was referring mostly to the game. Second, small roundabouts still take up space - and likely unnecessarily. That's because if the traffic is light in an intersection the roundabout isn't needed.

And to be fair the Welcome Rotonda in Manila-Quezon City is on a main road with (what looks like) 2 small side streets and 1 slightly larger road connecting to it. It also, on Google Maps, looks like the circle is broken by barriers so it isn't a true roundabout.

Perfectly round roundabouts are quite simple, once you master the game controls.
Probably the best thing to do is go into the asset editor so you build it once. You build it in quarter sections. It should really all just fall into place. Make the first quarter and then repeat 3 more times.

As Catratio mentions, the node points are important. So if you want roads joining at non-quarter points then you really just have to go free-hand by turning off all the snap-to-grid stuff.

Ok I improoved a bit but there is still problem with roundabouts. I made a screenshot of it. 3 of connecting roads are fine, but the bottom one seems to be broken and I can't find any way to fix it.

I did notice that the 'dodgy' piece was a one-way road whereas all the others are two way, so not sure it that's why it didn't render properly?

A couple of tips -
You may find that a roundabout that small will have problems will traffic flow when volume increases. That's because the road lengths are really small and you may find you only get 1 vehicle at a time (if bus or truck) on each section of the roundabout, meaning lots of stop/start as vehicles wait for road space to clear for them to move in to. So you may need to increase the roundabout size, I'd suggest 8 square diameter as a minimum.
You might also find using highway pieces for the roundabout instead will help flow. I've had roundabouts that 'gridlock' and when I switched to highway it freed it up. The Mass Transit DLC (which I see you have) has a helpful 2 lane highway which is perfect for this !!

make a few own intersections, from very very small Roundabouts to very very complex intersections you can place them all so often you wish

Yes, you do need to count the clicks of the distance.

You can use straight roads as a guideline that you'll eventually delete.

its just impossible to fix the problem I posted in my latest screen. I have also tried highways. One way is kinda broken. And sometimes when I build I see grass on the road.

Highways are picky, they don't allow right angle merges, whenever possible I prefer to build regular roads and upgrade to highways afterwards.

Sometimes you simply need to do it in the right sequence, because Part A blocks Part B, but you can place A after B

And yes, highways can be painfull

why not use the round corss roads thats in the game?
