How do you tag speed limits on curves and highway on/off ramps? At least in Ontario, these speed limits are advisory only and signed with a yellow sign (and sometimes on curves you will see a curve speed limit sign and a higher general speed limit sign right beside each other). I have used ramp_speed and curve_speed for this and taginfo suggests that maxspeed:advised, maxspeed:advisory, recommended_speed might be ways to tag this. See http://www.mapillary.com/map/im/nGxJnKpP2dootXNmp2eV_g for a typical example of a ramp speed limit in Ottawa, Ontario (this one is 60km/h).
Also how do you tag maxspeed which is unsigned? In Ontario the default speed limit is 50km/h in urban areas and 80km/h in rural areas when not signed. However, there have been proposals to lower the lower speed limit from 50km/h to 40km/h. I have been using maxspeed=national for this, is there a better way to tag this? _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
