Good on you Dave, I do like a good rant ! On Mon, 2014-03-17 at 10:47 +0700, Dave Swarthout wrote:

Great in an ideal world Dave. However, there are many highways in the world that are also 'tracks'. Recognising this, the OSM Lords have given us highway= tags to describe the purpose of a road. And tracktype= to describe the condition. Many cases, the tracktype= is not needed as its condition matches its purpose. But in situations where that is not the case, life threatening situations arise when a map user is not appropriately warned. I agree tracktype may not be ideal but its better that the rest and I think its too late to dream up a new one. > ...... those surfaces have an additional important characteristic > called smoothness. 'smoothness=' is not really appropriate as there are many, many roads that have issues beyond smoothness. I have seen tracks that appeared beautifully smooth but were beyond my ability ! > How a "highway" ever got a tracktype tag is beyond me and seems a big > mistake. That was part of the original definition of tracktype= when it was approved. > .... As far as smoothness is concerned, many have derided it as being > too subjective. Look, lets be honest, just about anything in this world except the integer series has some subjective aspect. Lets get over it ! > > say, "particularly regarding surface stiffness", IMO the word Yes, Dave, I agree, Fernando's use of the word 'stiffness' is a bit dodgy. But thats a 'subjective' opinion. > Perhaps soundness, permanence, or better yet, durability. No, I really think this is about how usable a road is given a set of vehicle and driver experience. We, on the AU mailing list discussed words like 'trafficability' and, from memory, some even worse ones ! But I do want a good solution and I'll agree to an OK one if its all I can get. I want to badger the renderers to take note of the state of a road before someone gets killed using an OSM map. Its only a matter of time.
