Why bus won't use roundabout

[M8asonmiller]

I built a bus line through a roundabout. Instead of passing straight through it exits, gets on the highway, passes into another part of my city, then comes back. Why didn't it go straight through?

I think the problem is that it doesn't have enough time to get over to the left lane, so it gets stuck in the right turning lane. I get this issue all the time on one-ways/circular routes, the trick is to move your bottom left stop one or two notches to the left, so the bus has time to get over a few lanes.

first off
don't place bus stops near a roundabout, it will cause traffic jam

secondly
try it with placing the line on the opposite side of the road

& yes, the bus lines are quite hard to draw
i had already several times the same problems
the last time i had to use the TMPE to direct the line on the roundabout explicitely along how the bus would "like" to drive to the next stop

do you use TMPE ?

You need to zoom out and show the whole bus route.
I believe it is simply that you have not taken into account that the roundabout is a one way ring road and the detour is the only way for the bus to complete the route and reach the stops you have placed. I cannot see the whole of the route to be sure though.

need to see how you have the roundabout set up via tmpe. also need to allow the bus to pick its lane when entering the roundabout, so that it is not forced to exit at the next road.

The problem is you have a stop right before the roundabout. This forces the bus into the right-hand lane when it gets to the roundabout which causes it to take the route you're seeing. You either need to move that stop further back from the roundabout (which is the smart thing to do, otherwise the buses will be clogging up the traffic trying to move through the roundabout) or you need to create a node between the stop and the intersection into the roundabout (which will allow the bus to switch lanes).

Not directly related to your issue but IMHO your line has too many bus stop. Cims can walk quite a lot, really a lot ;o). Especially in a city will a good pedestrian path network.
Less stop = better traffic; and the bonus of putting a bus stop seems quite large.

(I tink you can remove the 2 bus stop near the roundabout.)

Thanks guys. I will move the bus stop and see if that helps.

my bus network is a big ol spaghetti city and I'm scared to start messing with it but you're probably right

Where did the time go? I did what you guys said to do and it worked. Thanks again.
