If you're looking for a more common term, they're often referred to as "contra-flow cycle lanes". They're relatively important to distinguish, and need special infrastructure at the ends, so it's not as silly as it sounds to make this distinction. https://secure.flickr.com/photos/browniebear/3419618104/ https://secure.flickr.com/photos/browniebear/3419638932/ Other terminology: https://www.devon.gov.uk/index/transport/traffic/traffic_management/cycle_lane_road_markings.htm > 2.

No. This is not the place to make tagging proposals, and what we have right now actually suffices, even if it's a bit weird. Just tag to the highest level of provision on, or alongside the road, or use separate ways for segregated tracks, allowing roads with both lanes and tracks to be mapped. Easy. > 4.

It's been in the current state for over three years with precisely no indication from the renderer writers that they're likely to implement it. Why do you think your scheme is likely to gain any more traction than previous efforts? Let's concentrate on making the GB guidelines useful. Map common concepts and terms used by road-user-group-X to OSM concepts; sprinkle with pretty pictures; done. If you're going down the rabbit hole of deciding that an existing scheme is inadequate and therefore needs reinventing, you'll be wasting your time. > p.s.

Yep, agreed; it's in keeping with recent moves for separately mapped pavements too. -- Andrew Chadwick _______________________________________________ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
