Re: Osmand repeatedly wants me to exit and immediately reenter a highway

As I learned by now from https://forum.openstreetmap.org/viewtopic.php?id=68803, you actually do not have a common 100 / 130 @ 19:00-6:00 speed limit, but only because extra signs have been placed on the highway. So actually, in theory the exit lanes will have the same speed limit as the highway,

Re: Osmand repeatedly wants me to exit and immediately reenter a highway

Hi, I investigated a bit further, but some (OSRM) routers just seem to be pretty dumb. When routing from Wolvega to Sneek, it wants you to leave and re-enter the highway in Heerenveen, through a set of traffic lights! As for now I opt for not changing the max speed on the rejoin, but instead

Re: Osmand repeatedly wants me to exit and immediately reenter a highway

...still thinking about it... The two examples are when the slower joining road terminates at the junction between the off- and on-ramps. If there is no give-way/yield tagging (I don't know if OsmAnd does, in fact, pay attention to this) then it's impossible to know if traffic on the ramps

Re: Osmand repeatedly wants me to exit and immediately reenter a highway

Although some people don't like it openstreetmap can contain data about what is reasonable; we have https://wiki.openstreetmap.org/wiki/Key:maxspeed:practical For what it's worth, I'm fairly sure Google's algorithms take advantage of their equivalent of this based on logs of live traffic data. I

Re: Osmand repeatedly wants me to exit and immediately reenter a highway

Hi, It seems there is some consensus about the 130 limit on the on-ramp: https://forum.openstreetmap.org/viewtopic.php?id=70677 (in dutch unfortunately) so apparently this should be solved in the routing algorithm. I can see at least two ways to tackle this. 1 - I don't know how normal

Hi, Don't misunderstand me: I don't think it's trivial to solve, but I DO think it's very annoying. The suggestion by myxw...@googlemail.com is not helpful since it is distracting while driving. The OSM router makes even more mistakes like this, but on the other hand I can't remember such a

Re: Osmand repeatedly wants me to exit and immediately reenter a highway

I had a quick look at your examples on the openstreetmap site, and the OSRM router there does the same thing as OsmAnd, e.g. here . In both examples, both the
