[mkgmap-dev] check if road is connected to one side only

Would it be (without too much programming effort, nor too much computation time) possible to extend the current is connected check, to check for streets/lines connected to one side only? I would love to have road_class and road_speed lowered by 2- respectively -1 if this is the case.... Advantage would be a nicer routing graph I imagine - and thereby maybe a little improvement for long distance routing... -- keep on biking and discovering new trails Felix openmtbmap.org & www.velomap.org
