I see no need to separate mechanical from others in the major tag like traffic_sign=*.
I see no problem to add the information with another tag, maybe display_type=* Gerd ________________________________ Von: Colin Smale <[email protected]> Gesendet: Montag, 2.

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).

I only know them to be called a "programmable changeable message sign", so I'd probably tag it traffic_sign=pcms please, let's continue to avoid abbreviations. "pcms" is cryptic to me and likely to many others too. Wikipedia has an article about them called "variable-message sign" (IMHO sounds slightly nicer, leads to a shorter value and includes "non-programmable" signs: traffic_sign=variable-message_sign, even if the hyphen-underscore mix might lead to minor tagging inconsistencies). https://en.wikipedia.org/wiki/Variable-message_sign The article also states that a common name in the UK is "matrix_sign" (is ok as well, focusing more on the physical aspect than on the function). How about traffic_sign=variable? _______________________________________________ Tagging mailing list [email protected]<mailto:Tagging%40openstreetmap.org> https://lists.openstreetmap.org/listinfo/tagging _______________________________________________ Tagging mailing list [email protected]<mailto:[email protected]> https://lists.openstreetmap.org/listinfo/tagging
