You could read this http://wiki.openstreetmap.org/wiki/Tag:junction%3Droundabout If the area as got good bing it will be easier. If not I would sketch a plan, walk around the site and get some traces. If you mess up just don't save it. You could find a blank area on the map to do a practice, Do not save this practice of course. edit... I have now had a good look at this in Potlach2 you need to plot a few nodes around the mini roundabout you see in Bing, use the circle tool in the box lower right to make the circle neat.Now make it one way anti clockwise as it's USA. next connect the four roads to it by clicking their meeting points and pressing "J" for each of the four. Then remove the central node, make sure that's the only high lighted node when using the bin/delete symbol.Update the undo and redo boxes are useful,and after practice the problem with this method is that the circle tool sometimes moves the centre a bit upsetting the alignment. so use my other answer for best results. answered 17 Jul '12, 00:17 andy mackey |
Following a practice I have found this to be the easiest procedure.

I've taken Andy Mackey's answer, but just switched around a few of his points to make it a lot easier (for me at least). Where he starts, making nodes on the original road(s), made them behave (sometimes) erratically (i.e. deleting a complete road).
Good luck !!! answered 01 Aug '12, 11:13 LimburgCowboy Looking at the amount of times pops-up, would be great if someone could make a video tutorial of this.
