How should one tag suggested speeds (usually around curves) like http://en.wikipedia.org/wiki/File:MUTCD_W1-4.svg with http://en.wikipedia.org/wiki/File:Advisory_Curve_Speed_English_25.svg ? Should I tag them as maxspeed=*? I can see being cited for exceeding it according to the blanket safe speed provisions in some vehicle codes[1]. Don't. They're meant to be a driving aid, but aren't a fast rule (or they'd be on a white sign, not a yellow one). nothing in wiki and osmdoc has a view occurrences of advisory_speed= makes sense and is self explaining In CA, the standard speed limit on freeways is 65mph normally, but 55mph for trucks and towing/towed vehicles. This results in 9 tags(!), providing more reason for some sort of scheme like maxspeed=freeway. no please no more tags with fuzzy implicit meaning. this will create complete confusion and requires evaluation of the state polygons. how can a regular mapper and simple mapping tools evaluate such a tag in correct way. an average newbie mapper should be able to understand a tag without reading tons of docu.

Your are also maybe one of the is_in tag supporters because, hey, how can a simple tool find if an element is inside a polygone or not. Asking people to put on all roads the ten or twenty attributs making everyone happy like maxpeed, minspeed, averagespeed, recommended_speed, blind_in_one_eye_drivers_speed, width, noexit, maxheight is simply unrealistic, makes perhaps some lazy developers happy but is definitely not making mapping easy. Let the software do the boring and repetitive work for humans and not the opposite. Pieren ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

I'm not sure what FHWA's thinking was with the End School Zone sign (what about traffic that doesn't remember what the previous speed zone was because they turned into the school zone at a midpoint?). In Texas, I think the End School Zone sign does serve a separate legal purpose, beyond establishing the previous speed zone. Use of cell phones while driving is prohibited in school zones. (I think we are allowed to run over each other due to lack of attention in other areas.) As a general rule, a speed zone sign will be found within 50-100 yards of the end of a school zone. All the more reason to omit the redundant End School Zone sign, IMO; drivers should be focued on the task at hand at all times that they are driving, not just in school zones. ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

Hmm, I just checked a school zone near my house and I don't think that's correct. The 35 Mph sign comes before for the End School Zone sign. Do you have any source for that? Yeah, the US Manual on Uniform Traffic Control Devices. http://mutcd.fhwa.dot.gov/HTM/2003r1/part7/fig7b-03_longdesc.htm That's the 2003 edition. The 2009 edition removes that option. See for example http://mutcd.fhwa.dot.gov/htm/2009/part7/fig7b_05_longdesc.htm I thought school zones were designated by statute, not by sign. The signs are just there to remind people of the statute. The signs themselves do have consistency standards at the national level. Placing another speed limit sign before an end school zone sign suggests your local traffic engineer either can't read a manual or takes no pride in his job. Yeah, whoever put that sign up there screwed up big time. Still, for mapping purposes we should map the actual school zone. ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
