Do we have differing definitions of a Super Two? My personal threshold for 'motorway' is that potential conflicting traffic is grade separated. I'm not comfortable with tagging as 'motorway' any road that has at-grade opposing traffic. (Example: US 7 in between Arlington and Rutland, Vermont. Access is fully controlled, but there is no grade separation between opposing lanes. Climbing lanes are provided on steep grades, but passing in the oncoming lane is lawful in some straight and level sections.) And I'm not comfortable with tagging as 'motorway' any road that has at-grade crossing traffic. (Example: Taconic Parkway east of the Hudson in eastern New York. Dual-carriageway for the entire length, and all crossings with major roads are elevated, but there are occasional minor roads and driveways that cross at grade.) I'm not planning to tag or retag anything; I don't have a dog in this particular fight. I write this message as a data consumer. But I think that the tagging seen in http://www.openstreetmap.org/#map=19/41.88704/-73.76900 is utterly nonsensical. What the Sam Hill does it mean to have a 'motorway' that you tag as 'trunk' for barely the width of the intersection so that you can put a grade crossing on it? It might silence a warning about placing a grade crossing on something as a motorway, but there's no useful information to a driver. It's worse than useless - it raises the false expectation that the road is a motorway when it is not. It has grade crossings; it has narrow shoulders (not necessarily a disqualifier); it has the same speed limit as primary roads in its vicinity. It's a trunk road, or would be if we had designated trunk roads in the US. Tagging it as a motorway encourages unsafe driving, and at the threshold of an intersection is not sufficient notice to drivers of a downgrade. It would bother me a little to have either of these roads labeled 'primary'. It would bother me a lot more to have either one labeled 'motorway'. And the current tagging of Taconic Parkway offers the worst of both worlds. _______________________________________________ Talk-us mailing list [email protected] https://lists.openstreetmap.org/listinfo/talk-us
