Yes, they are mapped OK. But if the road has lanes that are separated with something more than a white line, you could also tag the motorway with two oneway ways (I can't see on the bing images if this is the case or not).

If you tag it with two oneway highways, then you don't need any turn restrictions.

Keep it simple and stupid! Two separate lanes are easier to evaluate than turn restrictions, e.g. if you add a directional maxspeed!

There are a few things that should be fixed here.
The on-ramp to B27 northbound should perhaps be split, like the one on the other side.
The on-ramp to B27 southbound has a broken turn restriction. The via-node is not the node between the from and to. It also has two ways with the to-role. Also, because the to-road is split and oneway, there is no need for the restriction in the first place.

There seems to be turning-lanes on the B84 that should be mapped individually.
The B84 bridge should also possibly be split, as it has a wide 'no crossing'-zone down the middle. This will also help mapping the turn-lanes.

B27 seems to have been split using a splitting tool (parallel ways). But one or more sections of the original way has been left in place. So now the road is triple...

best regards

@Sanderd17: Thanks. But B27 has only a white line.
@FK270673: Maybe KIS is good. But mostly the mappings are with a single street ...
@gormur: Thanks, but i think i have to do a closer look into what you tell me here. Im sorry, but most of it i do not understand for now.
I tried hard to not have broken turn restrictions with separeted nodes but i will again have a look into it.

@gormur: If im right, someone has done some editing after my last try from yesterday with turn restrictions and splittet B27 to avoid turn restrictions. So i have to do a closer look in the evening to understand all of it and to find errors.

@ALL: What i do not like is that with my testing and "navit" most was OK and then someone simply got over after i mentioned this here without telling!

@ALL: And the second thing: When someone is editing this, then complete your editing!

The turn restrictions are still there and i think some more errors are in place. Before that violence edit i tried to have a clean map. Now it is half broken and someone has to clean up.

I wanted to learn editing the map and not to clean up after someone!

Two oneways (ramp meeting a road for example) do not need a restriction. An example would of a valid restriction would be an intersection where a left or right turn is not permitted.

Hi again. Thanks to all who wanted to help me.

@FK270673 : No thanks to the person who destroyed my question.

Do you need any assistance in repairing these broken turn restrictions? Just send me a message.

Sorry for my edit! You may delete it at any time!
