Why not ask your question on the new OpenStreetMap Community Forum?


Total newbie. I've noticed in my area that there is a road that I know is two way for all but the last 100 metres or so. That last 100 metres is all vehicles in one direction and only buses and taxis in the other. Currently it shows as two way for the whole length. This means that sat nav applications that use openstreetmap (I've tried a few) always try and take you down that part of the road, which is incorrect.

So my question is how do I change it.

Thanks David

Remark at the 5th action: if not already present a new node has to be inserted into the way (the road) at the desired place first. Also see this more general question: changing-the-status-of-a-separate-section-of-a-road.

Thanks Cartinus. All updated, will see what happens next time I get a map update on my nav system.

You could use a Turn Restriction relation to define what is allowed to travel on a given part of the road. You can define the vehicle types ie restriction:motorcar=no_entry. Sat Nav applications should then pickup these relations (if they are any good). Turn restriction relations can be tricky to get right but the use of the JOSM editor and the Turn Based Restrictions plugin may help.

Don't use turn restrictions for simple one way roads. You would need three of them for every full intersection or two for every T-intersection. This is needlessly complex. A single tag (oneway=yes) on the road works better.
