Re: [Tagging] Feature Proposal - RFC - Tagging for complex junctions or traffic signals that are named
No tags on the shared nodes - just shared nodes. What is IMHO a quite bad idea for two reasons: – It’s unlikely that there will be software supporting features when there is no tag. – You would introduce a concurrent solution to a node highway=traffic_signals. I do not think that it’s a good idea to have various ways to tag the same thing. Made a test to show you what I was thinking. https://www.openstreetmap.org/#map=18/36.32478/139.10396 And there, you see even more problems: – At https://www.openstreetmap.org/#map=19/36.32487/139.10370, you do not have a shared node between the highway and the area. But this would be necessary to have a reliably hint for routing/turn-to-turn navigation software, otherwise it will be hard to know there the area ends. This would make a working routing solution quite unlikely. – At https://www.openstreetmap.org/#map=19/36.32492/139.10357 you have the area nearly in parallel to the footway. There will be other situations, where it will be exactly parallel. This is not comfortable to edit. – At https://www.openstreetmap.org/#map=19/36.32492/139.10347 you do not have a shared node between the footway and the area. But footways are not oneway. So a routing engine does not know when you enter the area respectively when you leave it. – At https://www.openstreetmap.org/#map=19/36.32440/139.10395 the footway overlaps only slightly the area. There will be cases where it will not overlap at all. How to decide reliably for software if this footway passes through the junction or not? – At https://www.openstreetmap.org/#map=19/36.32440/139.10395 you have a shared node. But probably, when you are passing through the footway and go from south to est, you do not pass over the traffic signals. (You would to so only when you go from south to northwest, and the traffic signal node should be at the intersection between the footway and the highway: https://www.openstreetmap.org/#map=19/36.32445/139.10392 ) – The complicate roule when to share node and when not will in practice be prone to errors. It’s to difficult. – And: I still not see what you gain with this. – And overall: It would mean that you may not add any of these areas to OSM unless you know _exactly_ where the individual traffic signals are located. So, in practice, either the tagging will hardly be used, or (what I think is more likely) people will tag nevertheless the area, and just not comply with the rule of the shared nodes. – All in all, I do neither see this practicable nor do I see a gain. ___ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
Re: [Tagging] Feature Proposal - RFC - Tagging for complex junctions or traffic signals that are named
Wow, you really went over it very carefully, thanks for all the input. I will go over your list of issues again, but can you fix it to as how you would see this tag used? I'm very interested to see how you would properly tag it, as you know the parsing methods much better than I do ('cause I have an idea of how they work, but no exact knowledge, so I'm dangerous). I only have one question so far- – At https://www.openstreetmap.org/#map=19/36.32440/139.10395 you have a shared node. But probably, when you are passing through the footway and go from south to est, you do not pass over the traffic signals.

Re: [Tagging] Feature Proposal - RFC - Tagging for complex junctions or traffic signals that are named
So the nodes where the signals_area intersects the highways is where the signals would normally be mapped for complex intersections? Not exactly. It would be difficult to do so if you have really complex junctions with really many individual traffic signals and you want to catch all of them – a zickzack that is not easy to draw and not practical to maintain. The area is drawn just _around_ everything that is considered the junction. About the individual traffic signals. We recommand as current best-practice to not map them if you use the area. Means: Don’t do both things.

Re: [Tagging] Feature Proposal - RFC - Tagging for complex junctions or traffic signals that are named
It should be pretty trivial to have the area share nodes with the highway ways where the signals would normally be mapped. Like drawing a square around a tic-tac-toe board, but the shared nodes are only on one side at a time. Also, I think It could also share nodes with the walkways and other pedestrian oriented ways, as the signal would be part of their routing as well.

Re: [Tagging] Feature Proposal - RFC - Tagging for complex junctions or traffic signals that are named
Okay, I’ve adapted the proposal wiki page. We can propose to tag complex traffic signal areas _only_ using the area, and not to tag the individual traffic signals. That makes it easier for renderers to display only one icon per traffic signal area. However, I feel we should not completly exclude for all time the possibility to tag also the individual traffic signals – it is at least a valid information, even if it is not necessary for traditional japanese maps. The individual traffic signals are simple nodes that are located within the area. We would not make it a rule, but just recommand to _not_ tag the individual traffic signals for Japan. As described in the proposal, the area is simply drawn around the approximative area that is affected by the traffic signals. It encloses everything, but shares nodes only with the incoming and outgoing highways.

Re: [Tagging] Feature Proposal - RFC - Tagging for complex junctions or traffic signals that are named
Differentiated tagging is needed for differentiated rendering. junction vs Signal. a single signal icon needs to be rendered in Japan for intersections. But that is yet working perfectly with the current tagging! In Korea, we have yet thousands of nodes with junction=yes and name=*, and they are rendered just with their name (and without any icon) at osm.org. Example: http://www.openstreetmap.org/#map=17/37.48391/126.65874 In Japan, we have yet thousands of nodes with highway=traffic_signals and name=*, and they are rendered with their name together with the icon at osm.org. Example: http://www.openstreetmap.org/#map=17/34.43281/132.46446 (I know that the rendering style is not very “japanese”, but osm.org has worldwide coverage and has to render something that fits best at least a big part of the world. But this is a _rendering_ issue, not a _tagging_ issue.) There is only a problem when you have to tag complex junctions or traffic signal systems with dual carrigeways, because you want that the icon the the name show up only _once_ per junction/traffic signal system, and not _multiple_ times. That’s what is proposal is for. is there a way to tell the renderer to not render it's icon if it is part of another area's way? that would allow the intersection tag to take over for the rendering of the signals for it's single icon. I guess you want to say that we have to supress the rendering of individual traffic signals (nodes with highway=traffic_signals) if these node are located within the area element that marks the traffic signal system as a hole. So we render only the area element and we get only _one_ icon and name per traffic signal system. Indeed that is exactly what is necessary, and I’ve made my proposal based on this assumption. I assumed that this is tecnically easy, but I’ll check this again… if that's the case: landmark=intersection ?

So we render only the area element and we get only _one_ icon and name per traffic signal system. Indeed that is exactly what is necessary, and I’ve made my proposal based on this assumption. I assumed that this is tecnically easy, but I’ll check this again… if that's the case: landmark=intersection ? Intersection=signals for Japan, intersection=junction for korea, or other named junctions. Again, I do not see the point in introducing here a new tag. Using the existing junction=yes in Korea and the existing highway=traffic_signals in Japan – just not only on nodes but extending it also also on closed ways (=areas) – should be fine. ___ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging ___ Tagging mailing list Tagging@openstreetmap.orghttps://lists.openstreetmap.org/listinfo/tagging ___ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging ___ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging

Re: [Tagging] Feature Proposal - RFC - Tagging for complex junctions or traffic signals that are named
in OSM we focus on ground truth and having a local (!) community taking care of the data and keeping it in shape. The expected iconography differs between countries, as they are shown on maps differently in the different countries. At least comparing Japan to America, what they expect to be displayed and how it is represented differs greatly. We have to be flexible enough to let the rendering of one country differ from one to the next, if if follows the societal conventions of their maps. If we can't designate a single signal icon for the complex intersections in japan, and offer named signals as well, we are choosing to make an inferior map for Japanese users because it doesn't conform to the groups opinion on what it should be outside Japan. So the sentiment about local users and whatnot is just puffery. Junctions naming in Korea happens to align better but ground truth is that people in Japan call them signals, publish maps with signals, show signals on signs, ads, billboards, and online - everything revolves around the consistent display of signals if we are going to render them. we will eventually have to clean up the multitude of signals rendered by OSM, and this is one reason why. This is a local tagging-rendering issue in search of a solution supported by the group - a single (horizontal?) signal icon is required to be displayed per junction with a signal, regardless of the number of actual signal nodes that are needed for a complex intersection, and it has to have an optional name rendered with it. Google conformed to this a few years ago, when they stepped up their mapping by importing and now improving zenrin's data. https://www.google.co.jp/maps/@36.4108183,139.3363032,17z?hl=en Apple's initial map was crap, mostly because it was based on old OSM data using imports that were never cleaned up. 3 months later, AppleMaps got a significant overhaul (they also imported and are now improving a local dataset), and every month they get better, even for me out here in the sticks. They also initially didn't support the signal icon, and now fully support it. PS - the Japanese post office icon is also used - another local custom we'll have to adapt to as well. Still waiting on the proper JR rail line rendering though. OSM will have to do it too. What other way do you suggest that this be accomplished? Pushing it off is an option, but this is something that a rendered map from OSM will eventually be *required to display this in this particular fashion* in Japan.

What would you gain in doing so? You have more tags, which means more work. But can you do anything that you can not do with the current, yet existing tagging? * highway=junction is impossible because the OSM database does not allow two tags with the same key on the same element. * junction=traffic_signals would also be problematic because in Japan you can have named traffic signals on straight road, for pedestrian crossing , and there is not any road junction.

Re: [Tagging] Feature Proposal - RFC - Tagging for complex junctions or traffic signals that are named
Correct me if I'm wrong, but it sounds like the end goal is: - to have junction names in korea, regardless of if they are traffic lights, and the symbol used there doesn't imply traffic lights, just a junction. - In Japan, the old junction system evolved to be named traffic signals, and the symbol used there a (horizontal) signal - so the end goal is to have the name and the signal icon shown over the intersection with it's name. so the complex solution is to map the the junction, (with different tags for Japan and Korea) with the area's way sharing nodes with the traffic signals. - in Japan's case, the complex solution must only render a single traffic icon, or it will ruin the purpose of using the intersection icon. Note: I'm not sure about Korea, but because there is no such thing as street addresses in Japan - just lot numbers in (sometimes random) sequence across the section, the sections are somewhat in a grid (regardless of what street is adjacent to the property, or what street it gets accessed from), all maps are used in a relative fashion (Start at Matsu Station, go two lights down, turn left at the temple, and turn right at intersection named Honcho 3), not in an absolute way (here's the 300 block of Main street, and my goal is 322 Main St, so it will be right about here). named intersections may be named in sequence, (Honcho 1, Honcho 2, Honcho 3 in order) but this is not really reflected in the location address. Any ad for a business or shop has a tiny map printed on it to show you the way to the shop, and most neighborhoods have residential maps on fences to show you where people live, to use if you were visiting some location before the days of Google Maps. in the past, adverts always used the common starting point of a train station, showing you how many actual signals, any named signals, temples, gas stations, or schools that were the way to your destination. This relative mapping has added Motorway Junctions and Primary Road junctions as starting points as time has gone on. The gist of what I'm trying to say is that accurately rendering a single signal icon is paramount for using a rendered map in Japan, because counting the number of signals between you and your destination is a commonly used and commonly advertised method of navigation when not using a GPS/NAVI. The western way of using street addresses and road signs displaying names of roads means finding your way without landmarks is easy, and it is what OSM is built around, but it is not the way people use maps here in Japan. Since Residential, Unclassified, and Tertiary roads are not named in Japan, the iconography and labeling of things besides the roads themselves is much more important.

No. We realize the name of traffic signal only for routing and navigation on local district. It is very separated concept from place (residence of human kind) tag or addr:* (postal delivery) tag. The name of traffic signal is not used as addressing system. And if there are very dense traffic signals, occasionally the names are like... XZY Conter(Chuo), XZY North, XZY West, or so. # XZY is the name of place or district, like Roppongi or Akihabara. Following maybe off topic... Hence, some JP mappers had proposed place=locality for old/famous name for mountain path crossing. e.g. XZY tsuji (辻, crossing) or XZY Touge (峠, peak). They may be acceptable, because we realize them as old/famous place name.

Thanks Did you have a look at the three existing proposals about complex junctions ? All are linked under: https://wiki.openstreetmap.org/wiki/Proposed_features/Junction Note, that in Germany micromapping is mapping highway=traffic_sign + crossing=traffic_sign/* on a node at the crossing and not at the intersection node. I even have found highway=traffic_signal at the road marking and another highway=crossing for the pedestrian crossing both in advance of the intersection node. Personally, I did start to add direction=* to traffic_signals for only one direction. Cheers fly ___ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging

@Simon are the names of the traffic signals/junctions actually used in addresses (and in principal would be a suitable value for addr:place in an address)? Hm, I’m not sure (I’m not familiar with the group of addr:* keys). At least they are places in the sense that they have a defined location. In Japan and in Korea, I’m not sure how this is handeled. In Ivory Coast, you have addresses like “in front of the XYZ crossroad” or “from XYZ crossroad 50 m towards the big fueling station”. Rather a sort of instructions for getting somewhere than an address in the european sense. Obviously “from XYZ crossroad 50 m towards the big fueling station” will be applied to various houses (usually, when you have arrived, you make a phone call to the person that you want to meet, and the person comes to the road to search you and help you with the last part of the way – I can guarantee you that this is very time-consuming ;-) Best regards Lukas Sommer 2014-08-25 15:21 GMT+00:00 Simon Poole si...@poole.ch: Am 25.08.2014 16:46, schrieb fly: .
