How to make a roundabout and bus station

Hi everyone.

So the last few days I’ve been getting used to the map editor.

It’s not going too bad but I have 3 problems I can’t overcome.

1, I can’t seem to build a roundabout. I can’t get the different types of road to connect and when using one of the junctions for road type 1i for the roundabout. I can’t get a different road type to connect. Especially the junction which has 2 ‘balloon’ on what appears to be the exit for a normal road.

2, I’m also having issues trying to build a bus station when using ‘ZOB’ roads. I can’t build roads within the bus station.

3, My final problem is I’m struggling to connect 2 different road types.

Any help on the above problems would be greatly appreciated.

Thanks in advance.
