Hi,
okay, I think I understand now better. mkgmap r2889 writes all route restrictions so that they prohibit pedestrians and emergency vehicles. RouteRestriction contains this: HEADER = 0x004005; If I change that to 0x004605 (as the wiki suggests) routing is allowed for pedestrians and emergency.
So, we can control whether restrictions apply to pedestrians and emergency.
Now I wonder if the old behaviour was intended? I think no. Both emergency and pedestrians can ignore signs like "no left turn", can't they?
it's something that can vary from jurisdiction to jurisdiction but i looked it up for New York state and the vehicle and traffic code there explicitly gives emergency vehicles engaged in a response permission to ignore turn restrictions and traffic control devices. but it's something you'd have to look up for each jurisdiction. when i set up no-u-turn restrictions for motorways in the US, i always add the except=psv tag so that it's made explicit. richard
