I think a better tagging scheme would be: active_traffic_management = variable_speed _limit active_traffic_management = hard_shoulder_running active_traffic_ management= ramp_metering
It keeps tthe tags taxonomically related and allows for other tags to be added as new schemes are devised or discovered regards Brian 2009/10/8 Jennifer Campbell <[email protected]> > There doesn't seem to be an established way to tag motorways operating > under active traffic management or managed motorway conditions (both are > essentially the same), or those running with variable speed limits, in > fact none in the UK seem to be marked at all. > > Active traffic management and managed motorways use hard shoulder > running, ramp metering and variable speed limits, so it may be a good > idea to tag each aspect individually, as they are not all present in all > cases. > > Ramp metering can be solved by tagging part time traffic signals on the > slip roads (I can't find a part time tag, but I presume part_time=yes > would suffice? > > For variable speed limits, would it be a good idea to tag > maxspeed=<default> (default is most likely to be 70mph) with > variable_speed_limit=yes? > > Would hard_shoulder_running=yes be appropriate for HSR or is the tag too > long? > > VSL is currently in operation on a large chunk of the western M25, part > of the M20, M1 J6-10, M40 J16-M42, M42 J3-J9 and part of the A470 north > of Cardiff.
