It depends on what you're comparing it to. versus implying it to be oneway=unknown, there's a reduction in the amount of tagging needed because less than 100% of the ways with highway=motorway_link need to be tagged with oneway=yes/no. And of course, a routing application specifically can't use oneway=unknown (they have only the choice of "use the way for routing" or "don't use the way for routing". So a routing application would have to make their own decision on which assumption to make) versus implying it to be oneway=no, there's *probably* a reduction in the amount of tagging needed, because there are probably more ways with motorway_link that are oneway=yes than oneway=no. In addition, for a routing application it increases safety. It's a lot worse to route someone the wrong way up a one-way motorway_link because it was assumed to be two-way than it is to send someone on a longer/slower route because it was assumed to be one-way. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
