First: Thanks for this OSM Mod. It works! But,, yeah there is a but. We all see the problem that CS sometime connects crossings, junctions perfectly and sometimes not. So I asked myself: Why? What is going on?

So I closely compared the imported Streets with Openstreetmap.org. (If you click on "Change" and then scroll very close you can see every streetconfigurations and nodes.) This is actually the Map.osm Data Info.

This is what I figured out: Let´s take the crossing "Goethestrasse" / "Dinghoferstrasse" in "Linz/Austria". Every street stops in the middle of the crossing at the Node. So there are actually 4 Streets. And the Node is the connection point between the 4 streets. Looking at CS it perfectly makes a crossing.

So...now let´s look at "Schillerstrasse" / "Starhembergstrasse". Schillerstrasse is passing right through the crossing. And so does "Starhembergstrasse". BUT there is a Node (!) in the middle, so Openstreetmap.org can recognize this crossing as a crossing.

But it´s actually a "fake" crossing!

This Node is like a glue which sticks the two streets together. And the Data says: "There are two streets, yes, but they are just passing by, like an overpass." And this is what you see at CS. Two streets just crossing without connection + sometimes a "Ghost Node" or a "strange Node" even sometimes "no Nodes".

Same with a T junction. If 3 streets have a Node as connection = Perfect, 2 streets (1 street passing thtough the Node) = no connection in CS.

I think that this is the reason why there are "Ghost Nodes" in CS. Those are the Nodes which have been made by Openstreetmaps (or the OSM community) AFTER the streets have been drawn to define this area as a street crossing.


(That´s also why the Mod "Move It" can (!) connect the streets (glue them together) but the game still can´t see it as a actual crossing)

I hope I make myself clear.

So 3 questions for all of you guys:

1. We can´t change every OSM Street so we can get a "perfect" Data in OSM, right? Or can we?

2. How can we identify the Fake Crossing Nodes in the OSM Data? One Idea I´m having is to find the same reference Node ID of two streets. This would mean, that this is crossing. ??

3. After we identified them: How does the algorithm look like, so we can fix the Data?

Or maybe we need to think more out of the box. Write a new Mode: "Every street crossing (even if there are different alitdudes) musst connect to a CS crossing." This would also connect the actual overpasses. But there are very few overpasses, right? Those can be corrected manually later on in the game fast.
