I'm sure I have seen combinations as well - big black LED panels which can show information including (for example) temporary/emergency speed limits if required.
Is there a need to distinguish between mechanical and electronic signs, which can only show a very limited range of signs for which they have been specially constructed? And electronic signs with a more generic capability which can show "anything", possibly with a limited range of colours? //colin On 2015-11-02 08:05, Gerd Petermann wrote: > I also liked the traffic_sign=variable, but now I think > > we have to separate those traffic_signs from pure informational > > displays showing e.g. temperature, wind, or other weather conditions, as well > > as traffic status (traffic jam, tunnel closed,free parking places and so on) > > from those which will always show a speed limit. > > I think the first group is not a traffic_sign=*, it is information=* > > For the 2nd group traffic_sign=* is appropriate, maybe like this? > > traffic_sign=speed_limit > > speed_limit=variable > > AFAIK, in Germany, those traffic_signs are only used on major > > roads (motorways, maybe trunks). > > Gerd > > ------------------------- > > VON: John Eldredge <j...@jfeldredge.com> > GESENDET: Montag, 2.
