Too many edges #297

Open tygrysio opened 2 years ago

Fedora 34. pgRouting-3.2.1. osm2pgrouting-2.3.8

When it imports the data for that area. https://www.openstreetmap.org/#map=19/53.43298/14.54038 It gets something like this.

Perhaps the problem stems from the fact that the road follows the same trail as the tramline. I think when the paths coincide, each node generates an intersection point. Maybe it can be detected and eliminated somehow.

When you mention "It gets something like this." the map shows only nodes and the data is osm data. A curved line geometry is made out of many nodes. I do not know which table you are showing on your image, but the nodes that belong to intersections are on table ways_vertices_pgr does the image of nodes come from that table?

tygrysio commented 2 years ago

Yes. Circles are nodes in the ways_vertices_pgr table. I used the map image to see it better.

I solved the problem with osmfilter. I have noticed that osm2pgrouting generates nodes when a road crosses railroads, pedestrian crossings and cycle routes. You can get rid of it by using an osmfilter .

There are also vertices whose origin I don't understand. Maybe they are the outlines of intersections or roads. However, I cannot get rid of them.

Roads are segmented like with speed bumps, stop signs, pedestrian crossings, etc
