How to query all junctions in a city

Question

I am trying to get the node (for the GPS) of all driveable junctions in a city.
Here is what I have tried out :

import overpy

api = overpy.Overpass()

osmid_f = 62422 + 3600000000

result = api.query(

f"""

[timeout:1000][out:json];

area({osmid_f})->.a;
(
  node(area.a)

  ['junction' = 'circular']

  ['junction' = 'roundabout']

  ['junction' = 'jughandle']

  ['junction' = 'filter']

  ['traffic_calming' = 'island']

  ['highway' = 'mini_roundabout']

  ['highway' = 'turning_circle']

  ['highway' = 'turning_loop']

  ['highway' = 'motorway_junction']

  ['highway' = 'passing_place'];

  node(w)(area.a);

);

out;

""")

But I get an empty result. Is there something I am missing ?
I would appreciate any hints.
Thank you

Your query is searching for nodes with all of those tags together. Make a separate query for each tag:

(
  node(area.a)[junction];
  node(area.a)[highway=mini_roundabout];
  ...
);

and so on. Some junctions might be modeled as ways, tagged as roundabouts (rather than mini_roundabouts).
