[Tagging] How to tag a "overhead electronic display" ?

[Gerd Petermann]

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).

That sounds reasonable.

I think we'd have to invent a tag.  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?
