[HOT] landuse=residential and routing problems

[Pierre Béland]

We have to understand that this is a sandy area in semi-desertic territory. Sometimes, we have too many infos (ie. all the paths of people going in various directions, taking shortcuts are printed at the rainy season). We have to interpret this info in the context of this semi-desertic area. And sometimes the traces + images in an area with no intense car circulation and no road infrastructure do not let us confirm from the image that there is a link passing through the village. Since there is no obstacles and it is logic that the two roads be connected, yes we draw the road link to connect the two roads where this looks the more logic.

Thank you all for your answers, and for your hints not to map too much detailed.
For my question, the key seems to be: "roads must share a node to let the routing software calculate...".
A lot of times I find situations like this one [1]: there are no roads connecting the highway from NW and the highway from SE, but I think routing sw must know the two highways are connectable...
So, I'm undestanding that sometimes it could be necessary to draw "virtual" roads around or inside a village, to connect between them several external roads (of course, if it seems appropriate, looking at the aerial images).If so, maybe it could be suitable to put a note (if not a specific tag), indicating that segment as "virtual"?
Thank you again,Marco
