I am having a similar problem. I was reading the man pages of v.clean. it
looks like you can at least get the intersection points by maybe patching
all the roads "A" and the others using v.patch. and then you can use,
v.clean input=patchedRoads output=patchedRoadsOutput err=points tool=break.
Supposedly, that should write the intersection points to "points". Maybe you
can rig something up with v.distance blahblahblah upload=to_angle. I'm not
sure if that would help.
