Roads that cross above one another

[Eugene]

Hi Fine people,

I have an issue on my routing index in that it seems to be treating a road crossing beneath a highway as an intersection.
The net result is that the route hops onto the highway even though it is impossible. How do i deal with this?

Cheers

Hi Eugene,

I think your roads data should contains some special flag like road level for this status.

For example, we have a road looks go intersection another road only by coordinates, but in fact it go on a bridge and the other road go through the aperture of bridge, so in this point your data need tell you this situation by some feature or flag.

And you should want to write custom code to handle this situation. When you build your routing index, you can handle the special situations in event.
