A lazy saturday with some hours behind the keyboard.

Roundabout ramblings

At one point I got interested in making “Nasjonal Sykkelrute 7” connected all the way, there where some breaks in the line. During this I also found out that a roundabout should not be segmented, why would it need to be that?

I found out a little later that this is probably because the different segments have different relations. Relations to bus routes, bicycle routes etc. So after commiting my well meant simplifications I went back and tried to clean them up. It made me more aware of how the route relations are built up.

Route me township

Inspired by this rudementary understanding of bus routes I scoped out the town where I grew up; Ulsteinvik. To my delight/horror there were practically no bus stops, nor routes mapped. So I chose a simple one and made the route=bus. Added the ways it covers, and the next step will be to add the stops.

Hi,

I too though roundabout had to be segmented for routes… turns out they don’t! So keep roundabout hole, not segmented.

Routes .. in version 2 formate .. take a look at my poor explanation osm.org/user/Warin61/diary/45106

There are at least two schools of thought on splitting a roundabout for routes.

I’m in the don’t split camp because I see the junction=roundabout as a single entity. Others want to split them because they think that it is more accurate.

As there is no consensus on which one to use I tend not to attempt to “fix” roundabouts as I don’t see it as a worthwhile use of my time.

Hello Warin and Swavu

Thank you for your comments and suggestions! I did not expect anyone to read this entry, and i got comments from strangers. That is inspiring and motivating :)

I think I agree with you both, my “ocd” wanrs roundabouts to be a complete circle. And it’s good to know that this should work with routes as well.
