[mkgmap-dev] Distinction between smooth paved/rough paved/unpaved streets

Hi, Here in my city there are basically 3 types of paving on streets: * Smooth paving (concrete or asphalth) * "Rough" paving (sett or paving stones) * Unpaved I have been tagging a lot of streets hoping to improve routing, but it seems to have no effect. In fact, I found the following rule: highway=residential [0x06 road_class=0 road_speed=2 resolution 22] It seems to ignore the paving type. Would be possible to assign different "road_speed" according to paving type? Thanks in advance, Alexandre
