Talk:Proposed features/recommended speed
moved page from ref_speed to recommended_speed --CygnusOlor 15:27, 4 May 2009 (UTC)
Actual keys in use
On december first 2012 I did a search on the word "speed" on taginfo  to try to find how people actually tag recommended maximum speed signs. I found the following in the first few pages:
* maxspeed:advisory 298 objects by 15 users * recommended_speed 162 objects by 26 users * maxspeed:recommended 61 objects by 18 users

Three years later...
* maxspeed:advisory 1869 objects * recommended_speed 420 objects * maxspeed:recommended 111 objects
This proposol might conflict with Proposed features/maxspeed none
The law citied on Wikipedia states the same as the regulation concerning sign #380 (above),which regulates particular roads, for motorway and trunk roads in general: That, if no other rule in place, drivers are _suggested_ not to exceed a speed of 130km/h on Autobahn and Autobahn-like streets (even on good road and weather conditions).
On the road this is merely indicated at the borders:
tagging on Autobahn as ref_speed=130 would make Proposed features/maxspeed none obsolete for german motorways.
- No, recommended_speed=130 implies maxspeed=none but does not obsoletes it. On non-motorways with recommended_speed=80-sign maxspeed=100 is implied. This means maxspeed should always be set! See the usage suggestions for relations on Talk:Proposed_features/maxspeed_none! --Phobie 15:02, 6 September 2008 (UTC)
- no is doesn't conflict with real maxspeeds or default-set maxspeeds, because "recommended speeds" are only "security advices" and have no meaning of are limitation like maxspeed does, so it neather implies nor obsolete maxspeeds. If there's a maxspeed set by sign (not by law-default) it should ber tagged with maxspeed=* seperatly.
- What about adv_max_speed (advised).--Skinkie 13:36, 17 September 2008 (UTC)
- same as above: recommended speeds are only "security advices" and have no meaning of limitation like maxspeed does. --Cbm 08:26, 3 October 2008 (UTC)
Better call it this tag 'recommended_speed' ?
- Yes, should change this proposal to suggested_speed or recommended_speed --Phobie 14:52, 6 September 2008 (UTC)
- But since the recommended speed is a recommended maxspeed we should better name it maxspeed:recommented in conjunction with maxspeed:practical --Phobie 21:23, 7 December 2008 (UTC)
This could also be used to tag the „Freiwillig 30 – Den Kindern zuliebe“ signs. In Germany, these signs often exist in residential areas where children play on the road but the normal city speed limit applies. The sign tells people to drive 30 instead of 50 km/h, but legally seen they don’t have to. --Candid Dauth 14:23, 2 May 2009 (UTC)
- Sounds interesting. "Richtgeschwindigkeit" has been abolished in Germany, so the tag could be used for that purpose. Might be difficult in countries where the official squared signs are still in place and others are set up by locals. --CygnusOlor 15:32, 4 May 2009 (UTC)
- even in counties where it's not abolished it would make sense. E.G. speedzone=city OR maxspeed=50 AND recommended_speed=30 --Cbm 16:10, 4 May 2009 (UTC)
"Richtgeschwindigkeit" is "maximum recommended speed"
I do think it's important to point out that there is no recommendation to drive at least at a certain speed in the German case (there is a general recommendation not to drive unnecessarily slowly, but I believe that fuel economy is a valid excuse for driving only at the minimum autobahn speed of 60 km/h).
There also used to be a minimum speed sign in Germany, but the sign has been dropped and remaining instances are being removed.

- I really hope they have a clause that one may not "hinder traffic by driving unnecessarily slow", as in other countries. Wasn't hard to find, actually: (2) Ohne triftigen Grund dürfen Kraftfahrzeuge nicht so langsam fahren, daß sie den Verkehrsfluß behindern. But how does this relate to (recommended) maximum speed, I don't know. Alv 11:36, 25 October 2009 (UTC)
