Why don't they go around thru my city?

So can anyone tell me why the cars go around? (i added the roundabout setup)

[frosty flume]

I highly question your roundabout setup 🙈

At no point you can get from inside lane to outside. And no entry goes directly to the inside lane. This means that your roundabout allows right turns only

[frosty flume]

Here you go

[vagrant linden]

Yea got it thx!

[vapid epoch]

@frosty flume How should a car go from the one on the right to the one one the left?
well, second thought, the already existing connection shall probably exit further on?

[frosty flume]

?

[vapid epoch]

I meant the one at the bottom

[vapid epoch]

ok, sorry, you are right

I always choose the outer ring only for the next exit

[frosty flume]

Here those slightly biased 2 lane RABs are quite common

Well... those are more like Turbo RABs, tbh

[vapid epoch]

I have no idea how roundabout in RL are but that is how I make roundabouts in CS

I think, in most cases roundabout in RL do not even have such dedicated lanes. The cars just choose where to go. It is just no functioning that way in CS, sadly

Lane connector should generally NEVER be used or a roundabout 🙈

A very unconventional way to set a roundabout up. It also may be that the game finds it faster to go around. This may be due to certain roads having a higher speed limit but it's hard to tell.

[frosty flume]

Very unconventional -> you can only take right turns or infinite circle

[ruby needle]

A BROKEN way to set it up.

[shy ridge]

Is there any way to create a turbo-roundabout without lane connector?

[west elk]

Kinda, yes

[ruby needle]

Well except for a turbo roundabout. But you need enough lanes for a turbo roundabout (usually 3 lanes)

And Turbo Roundabout without lane connectors = normal roundabout!

[shy ridge]

the number of (entrances+exits)/2 - 1, assuming you don't want to allow U-turns
Turbo roundabouts with different numbers of exits and entrances are possible, but a pain to work out

[ruby needle]

But you only have 2 lanes there!

[frosty flume]

Here they usually have 2

As I drew the connectors

[ruby needle]

No for a turbo roundabout.

Normal roundabout, 2 lanes is good and you don't need any connectors.
