Overpass request: Bridges, search the not preferred tagging

[Allroads]

How to find situations of this not preferred tagging as query in Overpass-turbo?

Suitable, also for steps and crossings.

[out:json][timeout:25];
way({{bbox}})[bridge][highway]->.all;
node(w.all)->.allpts;
way(bn.allpts)->.allconnected;
node.allpts(way_link.allconnected:3-);
foreach
{
  way.allconnected(bn)->.thisconnected;
  way.thisconnected[bridge]->.thisbridges;
  if ( (thisbridges.count(ways) >= 1) && (thisconnected.count(ways) - thisbridges.count(ways) >= 1) )
  {
    .thisconnected out geom;
  };
};

node(way_link: counts connected segments. This foreach{ filters out connections between bridges.

Thanks, a lot, a step further.

@Kovoschiz

node(way_link: counts connected segments.

I was allready working with part of the code (way_link.bstreets:3-) but got many mismatches and not found situations.

A T-junction where the way is ongoing. So that the bridgeway was connected to a middle node of the ongoing way, there is no :3- this is counting endnodes of a way. I thought.
But you solved that!

@Kovoschiz

This foreach{ filters out connections between bridges

That was many of my mismatches.

(way_link.bstreets:3-)
This also gave me, where the man_made=bridge is counted as a connection
If we could solve this in the code
This is correctly drawn in.

And other difficult thing is when a roadway split on a endnode of a bridge=yes , doing something with the angle of the lanes.
This is correct.

Such a angle is correctly found and wrong.

This makes code complecated.

For man_made=bridge , I forgot to filter in one of them after using a set way(bn.allpts)[highway]->.allconnected;
angle() in per_vertex() or per_member() doesn’t directly work for between 2 way … I’m not sure if building your own lstr() works, because pt( only seemed to accept numbers. Can’t evaluate a function to pass other coords to it.
You could try filtering them further in JOSM. I don’t know the MapCSS has such an angle function. At least you might be able to do some trigonometry from their coords to get the angle.

Solved, thanks.

@Kovoschiz

angle() in per_vertex() … to get the angle.

These less, less situations. And often it could be drawn in better.

I was trying the same setup for footway crossings included the fix filter [highway] for other polygons like area:highway

[out:json][timeout:25];
way({{bbox}})["footway"="crossing"][highway]->.all;
node(w.all)->.allpts;
way(bn.allpts)[highway]->.allconnected;
node.allpts(way_link.allconnected:3-);
foreach
{
  way.allconnected(bn)->.thisconnected;
  way.thisconnected["footway"="crossing"]->.thiscrossings;
  if ( (thiscrossings.count(ways) >= 1) && (thisconnected.count(ways) - thiscrossings.count(ways) >= 1) )
  {
    .thisconnected out geom;
  };
};

Green circle: These are correct, because, drawn in on the exact place, only end nodes should be filtered and controlled.
These should be filtered out, because they are correct.

Orange circle:
Here, there are no footways drawn in so the footway crossing does not pass the cycleway, a half crossing is set. Footways could be drawn in.
