This is something I brought up a while ago. Consider the following
A B C
--------+------->
|
<-------+--------
D E| F
|
\/
G
ABC is oneway in direction ABC
FED is oneway in direction FED
BE is twoway but is marked with direction BE
U turns are not allowed for FEBC nor are they allowed for ABED but all other
turn are allowed
In this situation the "via way" is BE and you create a no_u_turn trstriction
from FE, to BC, via BE. Up until now mkgmap would ignore this restriction as it
couldn't handle it.
There are loads of these near me and I suspect in many other places as well
Cheers
Paul
