Hi

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

  • Browse to the way on the map
  • Click on the triangle next to edit (near the top of the page)
  • Select "Edit with Potlatch 2"
  • Select the road
  • Select the node where the road usage changes
  • Click on the scissors icon (bottom right of the page)
  • Select the section of road that is oneway for all vehicles except taxis and busses
  • Click "advanced" (bottom left of the page)
  • Click "Add" (halfway in the left column)
  • Type "oneway" in the first cell and "yes" in the next cell
  • Click "Add" (halfway in the left column)
  • Type "oneway:psv" in the first cell and "no" in the next cell
  • Click "Save" (top left of the page)
  • Type a short description of what you have just done in the dialog box
  • Click "OK"

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.
