is mkgmap:road-speed-max still processed?
Hi, sorry for multiple reports, but nothing seems to work for me today. I'm trying to apply speed restriction as mkgmap:road-speed-max, something like this: maxspeed=* & maxspeedkmh() <= 60 { set mkgmap:road-speed-max = 3 } I can verify with echotest, that this tag is correctly applied, but then way is merged and default speed value taken. Probably mkgmap:road-speed-max tag is ignored by merge algorithm. no-merge-lines doesn't work (r2977) and I can't test what would happen without merging. -- Best regards, Andrzej
Hi Andrzej, the tag mkgmap:road-speed-max is evaluated like this: if(roadSpeed > roadSpeedMax) roadSpeed = roadSpeedMax; else if(roadSpeed < roadSpeedMin) roadSpeed = roadSpeedMin; You can use the switch --x-no-mergeroads to switch off merging of roads. Gerd popej wrote

Hi Andrzej, okay, that should be explained. The tag is evaluated after(!) style processing: If the way has a mkgmap:road-speed tag, the value is evaluated. The evaluated value is checked against the mkgmap:road-speed-max (default 7) and mkgmap:road-speed-min (default 0) values. Besides that you probably tested with an mkgmap version that contained the road-speed bug. Hope that helps? Gerd

Hi Gerd,
You can use the switch --x-no-mergeroads
Thanks, this switch works, i get separated ways.
mkgmap:road-speed-max doesn't work.
Echotag shows mkgmap:road-speed-max=3 but in img I get value 4 as defined with road_speed=4.

Hi Gerd,

I'm not sure what you mean by mkgmap:road-speed, I was referring to roads_speed=N form object definition. I have attached here simple source data with 3 primary ways. When compiling with r2979, default style and --x-no-mergeroads option, I get 3 roads, one with speed 4 and 2 roads with speed 3. With merging roads ways are merged correctly, this is improvement compared to previous mkgmap. Next I have added following statement at the end of "lines" file: highway=* {set mkgmap:road-speed-max=2; echotags "end"} Resulting img is the same, mkgmap:road-speed-max=2 is ignored. Next test, my statement changed to: highway=* {delete mkgmap:road-speed-class; set mkgmap:road-speed-max=2; echotags "end"} All, roads in img have gotten default speed 4, mkgmap:road-speed-max=2 is ignored. Last test: highway=* {set mkgmap:road-speed-class=3; set mkgmap:road-speed-max=2; echotags "end"} All roads get speed 3, mkgmap:road-speed-max=2 is ignored. All tags displayed by echotags are as expected. I execute mkgmap with following command: java -jar mkgmap.jar --route --x-no-mergeroads --style-file=styles\default maxspeed.osm -- Best regards, Andrzej
Hi Andrzej, I wanted to make clear the the min and max values are only evaluated when your style uses e.g. mkgmap:road-speed=+1 to modify the road speed class. Please check also the corresponding docu. Gerd popej wrote

Hi Gerd,
Please check also the corresponding docu.
Ok, my fault, thanks. I finally got it working, using statement "set mkgmap:road-speed=-0". Will this trick work in future? Manual says: mkgmap:road-speed, example: +1 Actually if I use "set mkgmap:road-speed=+1", mkgmap crashes. Example probably should include quotation marks: '+1' -- Best regards, Andrzej
Hi, we could also easily allow mkgmap:road-speed-max/min if mkgmap:road-speed is not set. I think the original intent of mkgmap:road-speed-min/max was that the mkgmap:road-speed modifier does not exceed some special limits. But we should not stick to it if the other handling is also useful. WanMil
