Way A has traffic “turn:lanes”=>“left|left;through|through|through|through;right|right”
Way B has traffic “turn:lanes”=>“left|left;through|through|through|through;right|right”
Way C and D do not have turn:lanes.
How to determine that the last lane of B Way also connects to D? Because there is no relation between B and D and C doesn’t have any turn:lanes information. I also looked at relations like route and connectivity from pbf file but didn’t find anything. If I want to have lane connectivity of this intersection then how can I do it?
There don’t seem to be connectivity-relations present in this specific location. I tried to read the data from osmium library. Is there another way to read connectivity-relations? Can you please verify if connectivity-relations are present there?
Is it viable to check if routes are present from B to D and then create connectivity?
I am checking the osm data using josm and I see that there isn’t any connectivity relation defined but there is a route described which goes from A->B->C->D. Considering the route I could create a lane connectivity rather than relying on turn:lanes only?
Any thoughts? Sorry but I have little or no prior knowledge of how to read osm data effectively.
