Wherever two straight links intersect, it will be an intersection.

I am wondering if there is a way to define at-grade separation where two straight link intersects?

My best guess is "NO". But really want to confirm with you.

Thanks,

your best guess is wrong, if you use Version 6 .
if you add one link with curvature it will not be an intersection with crossing straight/curved links. even if you remove the curvature from that link it would still not be an intersectin. add a node in one of the link and put some number in Z elevation field in the properties of the node. then see the simtraffic simuation, you have your grade separation.

Thanks. It is good to know!

To add to this topic, hold your [Ctrl] key when crossing links to create grade separation. This works for straight links.

Thanks John. Didnt know that.
