I think you might be able to fix this with micromapping. If you add the
detailed shape (i.e. the curve like it is signed on the road) of the
"junction" topology it might be solved. It is a general issue in many cases
that the junctions don't get modelled accurately (you can't determine from
the drawn shape which road is continuous and which gets discharged into the
other, because of oversimplification / bad generalization).
