Re: [Tagging] Traffic Lights, but only for one direction on a highway that isn't divided
Not the same situation here NE2. There are no traffic lights at all installed in either place for the inbound direction, just outbound. With the example you showed, the traffic light there still controls all directions expect for one lane. There are a few of those setups on US-17 North of the Trout River in Jacksonville for Southbound traffic. Anyways, here's the example I'm talking about: http://maps.google.com/?ie=UTF8ll=40.434715,-79.995511spn=0.00296,0.006968z=18layer=ccbll=40.434813,-79.995439panoid=xO1LWVjcCLODqDPmGf0fxwcbp=12,210.31,,0,5.68 Use to go past these lights alot when I was really young since my mom worked in the South Hills. Now, not so much since I don't go to the South Hills as often.

Here's my example: Here in Pittsburgh, when you're coming off I-579 going towards the South Hills across the Liberty Bridge, you encounter two sets of traffic lights (one before you get onto the bridge, and one on the bridge) because of two ramps that dump traffic onto it. The traffic lights are for outbound traffic only, as inbound (to Downtown Pittsburgh) traffic don't have to deal with them. Here are the locations of both sets: http://www.openstreetmap.org/browse/node/684666723 http://www.openstreetmap.org/browse/node/684666821. There is precedent for simply treating this as an ordinary traffic light, as sometimes there are lights that never turn red (due to lack of conflicting movements). For example, the rightmost lane here: http://maps.google.com/maps?gl=usll=28.494116,-81.374702spn=0.031494,0.082397z=15layer=ccbll=28.49391,-81.3746panoid=eqI0xGud1eZG-Wa8mhMJbgcbp=12,180.41,,0,3.52 ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

Re: [Tagging] Traffic Lights, but only for one direction on a highway that isn't divided
Trust me, if the Liberty Bridge had each direction divided, I would have divided it and wouldn't have needed to send in this question. But it isn't. :( It's a controflow-bridge. It's lane configuration on a typical day (starting @ midnight) is (outbound first; inbound second) 2-2;1-3;2-2;3-1;2-2 depending on what time it is (more lanes inbound during morning rush-hour; more lanes outbound in the evening).

[Tagging] ADR Tunnel Categories
ADR (see [1]) is a set of rules governing transport of hazardous materials by road, produced by UNECE (see [2]). It is responsible for those yellow/orange diamond-shaped signs on trucks with a UN substance number and particular hazard warnings. It also covers classifications of tunnels in major routes, so that transporters know what substances are and are not allowed through that tunnel. The applicable tunnels are categorised from A-E, where A means pretty much everything and E means almost nothing (by way of hazardous substances). All the tunnels and their classifications are published and signed on the ground. There aren't actually very many - the UK has only 9 for example - but this information is as essential for transport companies as max weight and max height if they ever transport hazardous materials. I have searched taginfo and the wiki for a way of tagging a road tunnel with its ADR category and found the hazmat tag (see [3]) which has a proposal on the discussion page for hazmat:tunnel_cat for this, but nothing seems to have come of it. I consider tunnel_cat to be too generic, as we are talking here about a particular classification scheme which has only been subscribed to by a limited number of countries, all of which are in Europe or North Africa (which is not surprising as the UNECE officially has a European scope). The tagging should allow for other classification schemes, and make it explicit which scheme is referred to. I was thinking of proposing the following: hazmat:adr_category=[A-E] to be attached to ways, normally through or adjacent to tunnels. The presence of this information will allow routers for HGVs to take this into account if they want to support hazardous loads. Any views on this? Would this need to go through a formal proposal, or is adding it to the hazmat wiki page enough?

Also useful for Recreational Vehicle (aka land yachts) - some tunnels require small natural gas or propane (cooking gas) tanks be turned OFF at the tank, some ban all tanks. So this is a useful attribute for a road net database that is to be used for routing. +1 (of course, we must be sure to source such data from appropriately licensed source or actual signage, not from commercial hazmat atlas.) OT - Only time in my long career that I've been paid to do GIS, I was producing hazmat atlases of a different sort -- where was the hazmat concentrated on the rail grid? -- Bill @n1vux bill.n1...@gmail.com ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

Here's my example: I'm pretty sure that the traffic signal tag as it currently exists is more concerned with whether or not a signal is present, not whether or not it is always lit, or faces all possible directions. Hawthorne Bridge's center span is a good example of a similar situation. http://www.openstreetmap.org/?lat=45.513539lon=-122.672664zoom=18layers=M http://www.youtube.com/watch?v=h4CneWT4ymM (also, this video of the bridge crossing makes me wonder...how do you tag two bike lanes in the same direction?

It's the first and oldest vertical lift bridge in the world, and has had three major retrofits to make it better withstand earthquakes (it crosses a major faultline), and to better handle the 20,000+ cyclists it carries per day (outnumbering cars and buses; there's been talk of converting the inside lanes to four additional bicycle lanes, two each way, but not sure how far it got before I moved). Given it's age, and the fact the outside lanes were added originally so trucks and buses could cross the bridge (as the original lanes, inside the bridge superstructure, are narrow), the bridge is old enough that it was originally designed around nonmotorized or horse-drawn crossings, and ultimately ended up having the approaches redone to handle increasingly large vehicle traffic. (also, this video of the bridge crossing makes me wonder...how do you tag two bike lanes in the same direction? lanes=2, oneway=yes it's the same as for cars. Otherwise it would be lanes=2, oneway=no Is lanes=* overall number of lanes (in which the example where there's two bicycle lanes would be a total of four lanes) or is it lanes open to all traffic (which would be just two lanes)? signature.asc Description: OpenPGP digital signature ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
