Hi, I'm a new comer working in/on Southern Alberta. Just getting to grips with the range of tags available, and have a question about passing/slow lanes.
By passing lane, I mean a section of non-segregated road which has an additional lane in one direction. This is often on an up-hill section where larger traffic would slow, however this is not always the case. Here they have built a series of passing lanes on Highway 3 (Crowsnest Pass to Lethbridge) instead of building segregated lanes. The same situation can occur where you have turn left/right turn lanes at junctions, which is very common here. The only suggestion I had was to set lanes to '1+2', which would mean 1 lane in the forward direction (of the way) and 2 in the reverse direction. If by convention the user was to use the 'normal' width as the first parameter then renderers which did not support this extra feature would be able to easy parse out the data. This obviously means sections of road might have the opposite way direction, but I don't think that matters. It would also require some fine tuning of which lane merged back into the normal flow, ie. did the 1st or 2nd lane have to merge? Comments? Cheers, Mungewell. _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk
