Re: [OSM-talk-be] Missing Maxspeed in Brussels
Defaulting to 120 is indeed very optimistic for those few primary streets where it is 120. On the other hand, I think that default maxspeeds in Belgium don't have a lot of value. The number of primary and secondary roads I know with maxspeed 90 isn't even half of the total of primary and secondary roads I know. The only streets for which a default is usable is for unclassified and residential. Although there is no possibility you can drive the allowed 90 on an unclassified road, and there are more and more residential roads with 30 as maxspeed. So you can hardly blame the tool for this. It's mainly about missing OSM data and poloticians trying to introduce as many different maxspeeds as possible (in the past, there was 50-90-120, now there is 30-50-70-90-120). In other words, since the road network is almost complete, tagging with maxspeed values is a priority for good routing. Regards, Sander.

The defaults are still 50-90-120, but I those politicians like to buy a lot of traffic signs I guess :-) The 90 was supposed to become 70 in Flanders though, but it's awfully quiet about that nowadays... In other words, since the road network is almost complete, tagging with maxspeed values is a priority for good routing. Also, do add the source of the maxspeed if possible, i.e. whether it's the default speed or whether there are traffic signs (and preferably whether the restriction is zonal etc.) THe biggest problem may indeed be the small unclassified roads with default maxspeed of 90, but where actually driving that speed may be suicidal. A router can't really know that, but that's where it should always try to pick higher classified roads.

Re: [OSM-talk-be] Missing Maxspeed in Brussels
Thanks Georges. I made some big changes in my area yesterday (14:00); According to the wiki it will update every day at 17:00 for the past day. No changes seen so far. I'll wait a bit longer, because this map is very useful in order to keep an overview of the missing speed limits. I'm experimenting with JOSM and trying to make a 'speed limit'-layer if possible.

Re: [OSM-talk-be] Missing Maxspeed in Brussels
1700UTC is 1 hour and 23 minutes ago. It's perfectly possible that updating the map takes more than that. So I would propose to wait a little more. It's also possible that the map isn't updating anymore since the redaction, but that's not easy to check. Greets, Sander 2012/8/6 Joren DC joren.libreoff...@telenet.be Thanks Georges.

Yeah i know this, but i wanted to specially highlight big highways without maxspeed to see what's missing ... but yes ito can surely help :) Regards, eMerzh ___ Talk-be mailing list Talk-be@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-be
