By common definition (and UN convention on road traffic), slow traffic is excluded from motorways (e.g. bicycles, tractors, mopeds) cheers, Martin ___ OSRM-talk mailing list OSRM-talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/osrm-talk

+1, I wouldn't exclude pedestrian areas from routing. They should of course be
connected, many situations would become islands if routing on areas is off.
One issue that currently is yet to solve afaik are pedestrian areas defined by
multipolygons, their ways should also be integrated into the graph

[OSRM-talk] crossing the dateline
I noticed that OSRM (or maybe this is only a frontend problem) is not aware of the lon-restrictions. Basically if you zoom out and drag the marker you get coords like this: 40.446947, 269.296875 when you try to route from one america to the other (e.g. in zoom 2 or 3), and no route is found. I believe it would be quite simple to solve this (long=long-180*math-floor(long/180)) or similar. cheers, Martin ___ OSRM-talk mailing list OSRM-talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/osrm-talk
Re: [OSRM-talk] Beginner question: default car profile and tracktype/smoothness/surface

In Italy (and elsewhere) we are using maxspeed=* for the speed limit, also if not signposted but implicit, and then add an additional tag source:maxspeed to keep track whether this is explicit or implicit: https://wiki.openstreetmap.org/wiki/Key:source:maxspeed (explicit limits get a "sign" value). cheers, Martin ___ OSRM-talk mailing list OSRM-talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/osrm-talk

This might be OT here, but I think you shouldn't use (i.e. "map") grade6 to
8 in OSM, as they are not defined. tracktype=grade5 is already the worst
tracktype (what in your scheme seems to be grade8), so anything above
doesn't make sense logically. See also actual usage numbers:

Re: [OSRM-talk] "Time-to-destination" on OSRM is too short
2014-02-10 14:16 GMT+01:00 Richard Fairhurst : > The correct solution is to add maxspeed tags, traffic lights etc. > +1, especially maxspeed is esential for travel times if there are explicit limits for bigger parts of your journey. Generally it seems that different ideas in different areas of the world, of what a "trunk" road is supposed to be, now fall onto our feet ;-) One option that comes to my mind would be that you change the road classification in Britain to use trunk only on those ways where it is used in other parts of the world, regardless of the actual official british classification. Could this find support in the British community? I guess that as a consequence you would probably have to change some trunk roads to primary roads, while much of the network would still remain like it is now. In Italy and Germany for example we use trunk for certain roads similar to motorways (i.e. usually no traffic lights, dual carriageways, no grade level intersections = slip ramps, but legally not a motorway). Motorway-like access restrictions are then added with an additional tag (motorroad=yes), so they are not compulsory in order to be a trunk road. cheers, Martin ___ OSRM-talk mailing list OSRM-talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/osrm-talk

Use tracktype and surface for other information. A grade1 track for instance is paved.

Erick, you have to keep in mind that the routing is not in every case performed on the map data you see in the rendering, because the routing database might have a different update frequency than the rendering database (it is 2 distinct databases, both derived from the same "master" osm database). cheers, Martin ___ OSRM-talk mailing list OSRM-talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/osrm-talk

Example crossing out of town where you can't turn: http://maps.google.de/maps?hl=de&ll=41.349801,13.75293&spn=0.013482,0.027788&t=m&z=16&layer=c&cbll=41.349827,13.753092&panoid=0dBb2Nn9tjfBufqt37g6xw&cbp=12,94.59,,0,23.63 > This proposal would also need routers to understand the law in different > countries. yes, at least if you wanted to handle also the stranger cases like the UK which allows turning on single solid lines. In Germany for instance I am not aware of any difference between a single and a double solid line (I think usually you get double lines close to situations where one of the double lines gets dashed, hence allowing crossing the double line only when coming from this side). cheers, Martin ___ OSRM-talk mailing list OSRM-talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/osrm-talk

Re: [OSRM-talk] road double continuous line
2013/4/17 Emil Tin > ** ** > > Divider=* was jsut a proposal, but it’s abandoned, and tag is not widely > used. > > yes, just a proposal. This "abandoned" status has nothing much to say, there was a wiki fiddler who set all proposals to abandoned which weren't voted on some time after the proposal was last modified. IMHO for how stuff is done in OSM it doesn't really matter whether there is a proposal or an "approved" tag, what matters is whether the tag is in use. Setting a proposal to abandoned should be reserved to the mapper who wrote the proposal (i.e. he made up his mind and discovered that the proposal doesn't work, and it isn't used by others the same time), as long as he is active. It doesn't really make sense to discourage usage of a tag simply for formal reasons (it wasn't voted upon in a certain period of time), in fact I have set some proposals to active which are widely used which the same wiki fiddler had set to abandoned. Now you are right, the divider tag isn't widely used, but I think this is kind of a hen / egg problem. As long as no routing engine processes this tag, people aren't interested in using it (it also isn't rendered, which is the main incentive for many mappers to use a tag). AFAIK there is no alternative proposal to map the divider, so for me if I want to map a divider this is the tag to do so. cheers, Martin ___ OSRM-talk mailing list OSRM-talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/osrm-talk
