Be careful, if you drop the class for traffic_signals it brokes long distance routing, because (at least in South America) a lot of primarys and trunks have traffic_signals.
I have been using the a map with a style that applies a -1 penalty for road_speed in case of traffic signals, and it works well in cities and in long distance routing, and it improves the estimated times.

In Massachusetts, *everywhere* is within an admin_level=8. One of these is Boston, which is very crowded, and there are towns with 300 people and probably more cows than that, over probably 40 km^2. So being in an admin_level=8 does not imply that you can't drive the posted limit. This "admin8 is slow" rule also fails verifiability as much as maxspeed:practical. > Accurate road speeds must be a good idea, giving better estimates of > journey time and, in some cases, faster routes.

To me it's clear that the right thing is to 1) tag major roads in cities with maxspeed:practical, if you can't drive at the posted speed and 2) respect maxspeed:practical. Just because the wiki crowd doesn't like is not that important; OSM has a culture of arguing about tagging in a vacuum rather than in the context of how data consumers use it, and this culture is broken. > To indicate slowed speeds at lights/crossings, need --link-pois-to-way > and, in "points", something like: > highway=traffic_signals | highway=crossing {set mkgmap:road-speed=1} > This, if necessary, chops the road up and applies the specified speed > to a short section around the point. That sounds promising. OsmAnd I am pretty sure adds time for traversing lights, but it isn't trying to program someone else's routing engine. I suppose the traffic_signasl (and stop) could also drop the class for longer segments if it basically works out the same. _______________________________________________ mkgmap-dev mailing list [email protected] http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev --------------------------------------------------------------------------------------------------------------------------------------- Con el nuevo beneficio fiscal, tu facturación electrónica puede ser sin costo.
