Hi Richard, please check: mkgmap treats except=psv like execpt=bus, and I think that's correct. Gerd Date: Fri, 20 Dec 2013 10:47:25 -0500 From: rwelty@averillpark.net To: mkgmap-dev@lists.mkgmap.org.uk Subject: Re: [mkgmap-dev] Route Restrictions On 12/20/13 10:20 AM, GerdP wrote:
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 _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
