Hi Paul,
Can I make this a feature request then? :) Consider the following
X
| 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
I have several of these near me and I'm sure they're fairly common (if not yet in the OSM database). Current mkgmap maps will tell me to make a U turn (FEBC or ABED)
Well, that's a lovely bit of ascii-art. I understand completely what you want to achieve. Isn't it the same as having a no_right_turn for BED and a no_right_turn for FEB?
Not, because if you come from X, BED is allowed, and if you come from G, EBC is also allowed. I don't know if XBEG exists in Pauls cases, but I have one like this in my city. Cheers Carlos
not sure if mkgmap or other routing tools can resolve it if the from/to ways are not both connected to the via node. then the relation should be like this. restriction relations are documented on the wiki that the via must be a node not a way. no_right_turn from AB via B -> instead way BE to ED crazy but this is the current definition of turn relations
Cheers,
