Route Avoidances via Stylefile and problems with roads vs non roads
1. I know that there was some talk about route avoidances in the mailinglist already. But I can't find it anymore. I want to set additional attributes (in the stylefile) to certain linetpyes so that you can exclude them from routing via the Avoid Settings. How do I add this info: Toll Roads Unapved Roads Carpool Lanes Highways What I want is to give highway=footway and bicycle=no the toll roads tag, so when I am using the autorouting I can exclude footways and ways unsuitable to bicycles by activating "avoid toll roads" or "avoid unpaved roads". 2. Why are motorways automatically autoroutable, EVEN if I don't assign road class and speed class to them and exclude them from the routable type (0x01-0x13), i.e. by attributing them 0x29! This is really annoying because if you built maps for cyclists you want to include motorways, but don't want them to be autoroutable. The only way I can currently achieve this is by commanding highway=motorway {set highway=_motorway} or similar. I don't even have the motorways in an routable layer. I put them into their own map creation process without parsing --route. I create the layers with this command: java -enableassertions -jar -Xmx6000M d:\garmin\mkgmap_svn\dist\mkgmap.jar --latin1 --no-sorted-roads --description=08_openmtbmap_%abr% --style-file=motorway --country-name=%country% --country-abbr=%abr% --mapname=%mapid%0000 %country%*.osm.gz and my main routable layer with this command: java -enableassertions -jar -Xmx6000M d:\garmin\mkgmap_svn\dist\mkgmap.jar --latin1 --no-sorted-roads --style-file=routable --route --country-abbr=%abr% --country-name=%country% --mapname=%mapid%0100 --%country%*.osm.gz
Hi Felix,
1. I know that there was some talk about route avoidances in the mailinglist already. But I can't find it anymore.
I want to set additional attributes (in the stylefile) to certain linetpyes so that you can exclude them from routing via the Avoid Settings. How do I add this info: Toll Roads
We currently recognise the toll=yes tag and set some bit of state in the map file but whether that actually has the desired effect, I do not know.
Unapved Roads Carpool Lanes
At this time, we don't know how to express those attributes in the garmin file.
Highways
Well, on my Etrex I can tell it to avoid highways when routing and it will not use any primary or trunk road (don't know about motorways as none are near to my cycling area).
What I want is to give highway=footway and bicycle=no the toll roads tag, so when I am using the autorouting I can exclude footways and ways unsuitable to bicycles by activating "avoid toll roads" or "avoid unpaved roads".
Why can't you just tell the GPS to route for bicycle (rather than car)? It will then respect the bicycle=no restriction.

Sorry, I don't know about that issue. Cheers, Mark

O.k. thats good to know. I will play around with it for a bit via {set toll=yes}

I tried that and it did not give any sensible results. Furthermore if you route over longer distances (try 50km) this setting is not applied. So I especially do not want to use it. Excluding toll ways does work very well even if you route from Austria to Spain or similar large distances (with Garmin City Navigator) however.

That produces crap routing. The road speed and road class is not really used anymore so you can't prefer pathes and footways over tracks and roads anymore by giving them high road_class and speed. Oh BTW I have huge problems with the routability of cablecars. Is there some code that only enables proper routing for highway=* and excludes buses, trains, cablecars or other that is not listed in the stylefile? Try giving powerlines routing information and you will see what I mean. You can have a look at my maps on openmtbmap.org if you fancy to get somehow sensible mtbike/hiking routing - meaning it will send you preferably to small ways and avoids anything big. The only problem is that Garmin still prefers ways with roadclass 0 and roadspeed 0 if they are very straight and few intersections over ways that curve around and instersected.
