-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 A | | D--+--B | | C Merging Center-A and Center B to one road can lead to a situation where you should get a turn left/right message but the device just think its a corner but no crossing. I don't know how Garmin handels merging on intersections. As I remeber correct you said, that they store housenumbers to roadsegments, so I would think that they split the road on intersections. So maybe we shouldn't merge highways, if there are more then two highways containing the same node. Henning Am 28.08.2013 22:07, schrieb WanMil:
If you merge two roads, that form a turn at a crossover, there could be missing announcement from navigation. This probably depends on angle, but I'm not sure about details. Again, I prefer to merge only roads that goes nearly straight.
What do you mean with "turn at a crossover"? I am not sure... Can you post an ASCII drawing?
