[When] 5 days ago [Comment] Thank you escada. There's a lot to consider for laneing since just numbered them in a old "routing"-way. I thought about the josm plugin but I don't have a computer compatible with the latest josm accept one I borrow from work when I have a spare moment, this will all need to be more manual for me. I've been tending a lot toward the area mapping camp, mainly because I started mapping narrow fottpaths that link very wide roadsmeaning linking to the centre way created a lot of confusing distotion in the map because of the fictious extensions required. Though area:highway mapping has been under appriciated (locally to where I map with other contributers) till recently and much more diffuicult than some people think due to the increase in node accuracy and problems of using picture backgrounds with lots of over hanging trees. though I see a logic for lane definition as the next step in adding practical detail especially for routing devices that handle this level like ,ordern sat-navs on major highways (at the moment - till we start feeding new stuff from the new tagging in OSM ;) ). My major dificultiy is that the roads I'm mapping have a lot of complex laneing and ghost laneing features, that work differently with diferent types of road-users. Forr example on approach to a roundabout a cycle lane (in-carrageway) widens the splits with one part crossing diaganly across another vehical type's lane before sometimmes settleing between two others futher along. This enables road users to pridict each others paths easier and in theory improve things. Onther complex arangement is at rounderbouts that have been given lane markings painted as sometimes (espcially at part also retro-fitted (or now pre fitted) with traffic-lights) when there are several sets of lanes that are superimposed into the same place (ie 4 lanes continueing around but also 5 lanes leaving and then 4 lanes pulling off through the middle to a half flyover - now these lanes aren't alongside each other but painted over the topand though each other the th=raffic light phases orhcastrat sainty in the flows by traffic taking turns to use the differnt alignments though sometimes its up to the divers to weve though each other in there lanes by speed adjustment. All this is cool till you try to adapt lane designation tags to it! I'm thinking that the routing way (routing being its main function when areaisation uses a lot of area:highway's) is also like to be overburdened when I have to split it for the rapidly varying multi-clausal parking rules (I counted about 50 on one local residential streat alone (they asked each terrace house what they wanted right outside the house because it getting so contentious!) This might not sound very positive but it just the sort of real-world "fun&games" type problems that keep thing intreasting and making it less mundane. I think in the end I'll wind be let to add area:highway=lanes across each other in a superimposing sence and just leave it to the consumer to figure out how to present it all. though the use of accesstype and placement tags (giving forking lane gidance could see it wind up makeing logical sence at least to a routing algorithum). But fist I've got to wade though the [tree-]crowns to get the sidewalks linded up right. Then onto happy lane mapping. Thanks again for your very useful links. -Govanus [Post]
