That's what I wasn't clear about above. Though Wikipedia's articles and the actual ground truth seems to show that what is signed as US 75A is actually OK 75A, since it seems Oklahoma considers US bannered/lettered routes as state highways and may not consistently sign it wholly as a state or US highway. Another highway with confusing inconsistencies would be US 412. Parts of it include: - Cherokee Turnpike (signed as Cherokee Turnpike, not signed as US412). - US 412 Scenic (old US 412, a loop bypassing the Cherokee Turnpike, the last free exit in both directions where the turnpike starts; signed as US 412S or US 412 Scenic). - OK 412A (not sure of signage, but is definitely related to US 412; may actually be US 412 Alternate) - OK 412B (not sure of signage, but is definitely related to US 412; may actually be US 412 Business) - OK 412P (signed as OK 412P, definitely a spur of US 412 at the Arkansas River Navigation System; may actually be US 412 Port) Arkansas seems to have similar quirks to Oklahoma on US highways between the Cherokee border and Bentonville; not sure if this is regionalistic signage issues or if the business/alternate/port/scenic roads are really state highways as a result. ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us

How is putting banners in the network tag preferential? why not something like... network=US:TX:FM modifier=Business network=US:US modifier=Business is_in=Maryland Each of the potential tagging schemes had drawbacks. One of the chief drawbacks of this one is that a naive data consumer that looks at the network and ref tags but not the modifier tag will get drastically incorrect results. (If it looks only at the network tag, then that's useful information on its own. If it looks only at the ref tag, it's not that useful, but it's also not likely to come to incorrect conclusions about the data.) For the record, the drawbacks of the other approaches are: * network=US:US, ref=50 Business Mingles base reference numbers and route modifiers together in a way that's difficult or at least annoying for data consumers to process. Addressing this problem was one reason for separating the network and ref tags on route relations in the first place. * network=US:US:Business, ref=50 Separates mainline routes from their alternates and variants, even though all of them are, outside of OSM, in the same road network.

Hence why it's important to have the discussion. After more thought, in the general case, deprecating modifier and just using network to denote variations using the established : separator convention is probably sanest. As Phil points out, while no solution is ideal, the only pitfalls with * network=US:US:Business, ref=50 are hypothetical; AFIAK there is no data consumer other than the shield rendering project at the moment anyway, and this solution has the best potential of alerting the consumer with a I don't understand this input - modifier is too easy to overlook and requires multilayered logic and overloading ref produces freeform that needs parsing. For example: Pythonish pseudocode parser using just network and ref: shield_content = relation.ref switch relation.network: case US:US: shield_design = 'US.svg'; break case US:US:Business: shield_design = 'US_business.svg'; break ... otherwise: printf('network tag %s unrecognized', relation.network) end switch shield = render_shield(shield_design, shield_content) pseudocode parser that needs modifier too: shield_content = relation.ref switch relation.network: case US:US: switch relation.modifier: case Business: shield_design = 'US_business.svg'; break ... case NULL: shield_design = US.svg; break otherwise: printf('modifier tag %s unrecognized for %s\n', relation.modifier, relation.network) end switch ... otherwise: printf('network tag %s unrecognized\n', relation.network) end switch shield = render_shield(shield_design, shield_content) pseudocode parser that has to figure things out from the ref tag: if ' ' in relation.ref: // Hope they remembered the space! ref = relation.ref.split(' ')[0] suffix = relation.ref.split(' ')[1] else: ref = relation.ref suffix = NULL switch relation.network: case US:US: switch suffix: case Business: shield_design = 'US_business.svg'; break ... case NULL: shield_design = US.svg; break otherwise: printf('suffix %s unrecognized for %s\n', suffix, relation.network) end switch ... otherwise: printf('network tag %s unrecognized\n', relation.network) end switch shield = render_shield(shield_design, shield_content) The code for just using network and ref is far simpler. The tagging may not be aesthetically perfect but relations are non-newbie-friendly almost by definition, so any tagging solution for this problem is going to require mappers to learn the tagging style anyway.

Who cares about AASHTO? When did they become the bosses of OSM ? Sure we're free to consider their opinions but doing so at the expense of OSM is stupid. I've seen the network tag, from the start as a way to describe the sign with increasing specificity and an opportunity to gracefully fall back to a reasonable default. So if I'm not rendering the green-variant US:US:Business:MD I can fall back to US:US:Business, or even to US:US. Does one renderer or another want to do something smart with other local variants? If it's tagged, they can. Our North American highway signs inspired no interest from our European cousins so this solution is entirely ours. Overloading highway with modifier=business, truck=yes,loop=yes, alt=yes, or whatever, just seems silly. To describe a single, awesome sign.

I had actually planned on attaching Maryland's US Business shields to the US:US:Business:MD network once I made them, but I haven't gotten to those yet. Personally (and you can take my thoughts here with a grain of salt) my original thinking was (whether clearly communicated or not): network=* should represent a broad shield type, roughly corresponding with the core sign design in question (which is largely universal, in the sense that all numbered routes are part of some network - N routes in France or Ireland, federal highways in Mexico, whatever) ref=* what varies on the shield itself between routes in the same network (maybe the number/designation... maybe the number with a suffix, like bis in several European countries). modifier=* would represent MUTCD-type banners attached to the shield (which are largely a North American thing - in retrospect I probably should have just called it banner) and/or weird stuff like Georgia's CONN. that you need to distinguish but would look silly at the same size as the ref. That said it may be easier to combine modifiers/banners into the network as subtypes. Renderers can fallback to the longest left-anchored substring they understand for weird things they don't understand. Whatever folks want to do (including modifier - banner) would be fine with me; it's not like there are thousands of relations that would need to be changed to the consensus that emerges. As far as non-AASHTO stuff like US 70A (which I'm pretty sure AASHTO considers Alternate US 70), my gut feeling is to tag how it's signed in the field even if it's not technically correct - e.g. network=US:US, ref=70A - as long as we're talking about single-letter suffixes. I still haven't really thought through what to do about Arkansas' irritating redundant signing style (Truck AR 7T), although there again field signing (ref=7T, network=US:AR:Truck or ref=7T, network=US:AR, modifier=Truck) is probably less likely to result in data consumer confusion based on naive rendering than doing something technically correct - presumably at some point AR 7 and Truck AR 7T intersect, so you'd want the map or your GPS app to distinguish clearly which one is which.

To me, US:US:Business:MD falling back on US:US:Business is fine. Tagwatch processes should catch common cases like US:US:Alternate and US:US:Business and ensure they get rendered correctly. OK, I'll bite. How is putting banners in the network tag preferential? why not something like... network=US:TX:FM modifier=Business network=US:US modifier=Business is_in=Maryland ...instead? ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
