Couldn't they just ask, possibly using "Freedom of Information" legislation? This case would not require very accurate positioning at all. I wonder whether this is a good use case for OSM. > When we also draw the sidewalks as areas, nagivation software could > take the position of the poles into account to calculate routes for > wheelchairs or trollers in case the sidewalk is becoming too small at > a pole. All that is needed for this, is a "highway=pole" node, or even "highway=obstruction", which would have the advantage of being able to cover other things like street lights and waste bins. This case would require very accurate positioning and good mapping of pavements to be useful, but associating the pole with a road is not required. Neither of these cases are for the car drivers... //colin___ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging

Hi all Le 21 mai 2017 21:25, "yo paseopor" a écrit : Node could be in a way. Way has a direction We can use forward and backward keys, and also side=right/left/both to orient the traffic_sign. I don't support this because signs are often beside the road and not "on" it.

Of course it's always possible to guess a place next to the road, but even with your proposed side=* tagging, that's not nearly as good as being able to map the actual location. Also consider that not all signs clearly belong to a single road, for example [1]. Plus there are traffic signs which are not next to a way at all, but e.g. on a pedestrian square or a parking space, which can only be mapped using separate nodes. Likewise, the direction key in your proposal is currently limited to forward and backward. However, there are also signs facing sideways as in [2], or at an arbitrary angle. Using a separate traffic_sign node together with the direction= tagging (that has already been approved, by the way!) works in all these cases. Happy mapping!
