Some routing software warns of such exits (as opposed to those where you must turn off to leave the main road).

[Tagging] Tagging churches that use non-church buildings.
I'm was planning to add a church to OSM - the only problem is that the church doesn't have its own building, but rather uses a school hall. I've asked the Australian mailing list for ideas, but I thought I should ask here if anyone here has any tips or has come across a similar problem. The church has used the school hall for about 10 years. I know of a few other churches in Australia that use other facilities like halls rather than using their own building. Presumably it happens in other countries, also this may be relevant for other buildings with multiple uses. The school is currently marked with a way surrounding the grounds. I am planning to add the buildings. The church meets in the hall that is in one of the buildings (not the complete building). The options so far suggested at talk-AU are: - don't tag at all (are we marking 'buildings with pointy roofs' or 'building that congregation meets in?) - add a node for amenity=place_of_worship inside the relevant building, with note=church meets in school hall (this is my preferred option but I'm not sure if there's a better way to tag it) - use amenity=school;place_of_worship over the building - use a relation for the church over the building outline and a separate relation for the school for all the buildings (I'm not keen on this one as the amenity=school is already used for the school boundary). - amenity=school , place_of_worship=yes (again I'm not keen on this one) The church is located here: http://www.openstreetmap.org/?mlat=-33.42085mlon=149.57153zoom=17 If anyone has any ideas, please let me/the list know.

Re: [Tagging] Counting lanes: include merging or turn lanes?
I have been thinking recently about how to represent special lanes in OSM. I have been working on a flexible scheme for this which I am calling lane groups. Below is my current draft...If there is any support out there I will turn it into a wiki-page and get the ball rolling. All comments are welcome! lanegroup tag In order to support the construction of spoken navigation instructions and junction view functionality it will be necessary to indicate how a road is divided into (groups of) lanes and how these lanes are designated. By grouping the lanes of traffic into groups, the characteristics of each group of lanes can be tagged, without having to define each lane as an individual way or having to define junctions as complex relations. The idea is to create a simple, pragmatic but effective way of recording the information into the database, without creating a substantial workload for mappers. One-way ways The lanegroups are numbered from left to right, irrespective of whether one drives on the left or not. So in the UK (driving on the left), at a simple motorway exit, lane group 1 would be the lanes to take the exit, and lane group 2 would be the lanes to continue on the motorway. At a similar motorway exit driving on the right, lane group 1 would continue straight on and lane group 2 is for taking the exit. Two-way ways Lanegroups are once again numbered from left to right *as seen from the forward direction of the way*. An approach to a cross-roads with dedicated lanes for turning left and right (in the UK) would therefore have (in the forward direction of the way) lanegroup 1 for turning left, lanegroup 2 for straight on, lanegroup 3 for turning right, and lanegroup 4 for the opposite direction. If the junction was symmetrical, approaching the same junction from the opposite direction (now in the reverse direction of the way) would have lanegroup 1 for the opposite direction, lanegroup 2 for turning right, lanegroup 3 for straight on and lanegroup 4 for turning left. Tagging All tags are to be applied to the Way only. Information related to the lane group could include: * number of lanes * direction as related to the direction of the way * intended direction * access restrictions for certain vehicle classes (this can cover dedicated bus lanes etc) * access restrictions for certain times of day (this covers special rush-hour-only lanes) * signage There is currently no way to have a list of subtag values other than key=value1;value2;value3 etc. As the number of lanegroups will in practice not exceed four or five I suggest using simply lanegroup1, lanegroup2 etc. Example - motorway exit, driving on left highway=motorway oneway=yes lanes=2 lanegroup1:lanes=1 lanegroup1:intention=exitleft lanegroup1:signage=A1234;Town Centre lanegroup2:lanes=2 lanegroup2:intention=straighton lanegroup2:signage=M1;The North Example - urban crossroads, driving on left, no left turn for HGVs highway=primary oneway=no lanegroup1:lanes=1 lanegroup1:intention=turnleft lanegroup1:hgv=no lanegroup2:lanes=2 lanegroup2:intention=straighton lanegroup3:lanes=1 lanegroup3:intention=turnright lanegroup4:lanes:2 lanegroup4:direction=reverse Note that I do not intend this to be used for routing as such. There are already methods of indicating turn and access restrictions etc. Lanegroups are to form a basis for junction view type applications. Editor support It would be nice if the OSM editing applications were to support lanegroups. One action which would benefit from support is reversing a two-way way's direction - which would affect the numbering of the lanegroups. Further work For best effect it would be nice if we could arrive at a consensus on the two subtags which are really new, namely intention and signage. To kick things off I would like to suggest the following: intention mergefromleft (for traffic joining from left) turnleft (more or less 90 degrees) exitleft (shallow angle) straighton exitright (shallow angle) turnright (more or less 90 degrees) mergefromright (for traffic joining from right) signage line1;line2; etc possibly a way of identifying the road number, such as wrapping it in some kind of brackets, e.g. [A123], so it can be displayed with suitable emphasis Also the relationship of the main lanes tag to the lane groups should be explicitly defined. I suggest that it contains the number of through lanes only, so a typical motorway will have lanes=2 or lanes=3 for most of its length, with the lanegroups being used for occasional extra lanes for the exits.

Generally, no. On a lot of the freeways near me, they have two main driving lanes on each direction, so I set it up as a dual carriage way with one-way on each side, and mark each side as lanes=2. The question comes in for the on/off ramps. There are sections where two intersections are somewhat close together, and so there is an on- ramp, a long extended merging lane, then the next off ramp. Strictly speaking, there is a third lane for some distance between the the ramps, but it isn't a through lane. There are only 2 driving or through lanes in that section of freeway. See for example hwy 217 between Denney and Allen at: http://www.openstreetmap.org/? lat=45.473345lon=-122.786743zoom=18layers=B000FTT I generally, form the intersection of the ramp with the main roadway at the point where the solid line starts or ends - the first place you can legally merge from an onramp or the last place to an offramp. In this case, this leaves too short a section of 3-lane main roadway to bother breaking it just in order to tag that short section with the extra lane. I see the lanes tag being useful primarily in determining likely speed possible in making routing decisions, other factors being equal. It could also be useful in rendering. Neither would seem to sway me to add the extra lane for such a short distance. I-10 in this area http://www.openstreetmap.org/? lat=34.03753lon=-118.280316zoom=18layers=B000FTF might end up being an exception in some places (I didn't look closely, but it comes to mind). I have only been counting the driving or through lanes, so I have tagged this as lanes=2, and just ignored the short extent of the extra merging lane. Agreed. Likewise, there are suburban streets that have an extra turn lane just before an intersection, like Murray Blvd at: http://www.openstreetmap.org/? lat=45.4814lon=-122.8261zoom=18layers=B000FTTT As one big street with two driving lanes each direction, I've tagged it as lanes=4 and ignored the short extent of the extra turn lane. Because that center lane is present between intersections as a center turn lane, I tag lanes=5. This, to distinguish it from roads where there are only 4 lanes (2 in each direction) for the stretches between intersections, since left turns without that center turn lane cause more congestion (again thinking of speed estimation). I tend to discount restricted, merging and turn lanes myself, and count restricted lanes as a seperate way as a stop-gap measure until lane restrictions are more or less sorted. I wish I had a better tagging solution than that, since a lot of interchanges in Portland are behind blind curves in no-lane-change sections. ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
