[mkgmap-dev] Roundabouts causes crashing devices
Hi list, Many users of my Openfietsmap are reporting crashes when approaching roundabouts. Some notice it before they enter the roundabout, others report that the device dies on the roundabout itself. In many cases those roundabouts are with cycle routes, so I have removed the bicycle routes from those roundabouts. Some report this fix works, others still complain of crashing the device. There are also cases without any cycle route involved so I wonder if this happens only with my maps. It happens with recent GPS devices like the Oregon 6xx series, Garmin Edge Touring and 8xx, GPS map 62 and 64. It does not happen with older devices. I cannot find any roundabout in my vicinty to reproduce it so it does not happen all the time with every firmware. The only thing that all those reports have in common is that it happens near a roundabout, the device is dying slowly, turning it back on will make it work again. Did anyone here have seen the same behaviour? ___ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
Re: [mkgmap-dev] Roundabouts causes crashing devices
Hi Minko, for my trip to Sicilia I used a map from http://garmin.openstreetmap.nl/using the Openfietsmap Lite style. I also noticed quite a lot of crashes (maybe one per day) on my Oregon 600. I did not relate that to roundabouts but in Italy a roundabout is never far away. Most of the time I followed a track, so I think they were not related to routes. BUT in one case the device crashed two times within a short time, and yes, I was aproaching a roundabout and using a route calculated by the device. I still have the recorded gpx files and the img file for the map in case these can help you. Gerd Von: mkgmap-dev im Auftrag von Minko Gesendet: Freitag, 8.

Re: [mkgmap-dev] Roundabouts causes crashing devices
Hi Gerd,
Interesting to hear because on Sicily there are hardly any cycle routes, if
any, on OSM, so it could be also associated with something else.
Can you give just the location of that particular roundabout on the osm.org map
so I can see if there are similarities with other roundabouts?
I think about too many OSM nodes, the roundabouts on the mkgmap maps are
sometimes distorted if drawn with a lot of nodes. Maybe this could cause
crashing of the device?
Another more likely cause could be that I use an invisible line type for 0x0c:
junction=roundabout [0x0c road_class=1 road_speed=1 resolution 24 continue
with_actions]
junction=roundabout {set access=no}
The line that is rendered on my map is not accessible, for instance an
unclassified 'white' road with 0x06 is drawn on top of this invisible 0x0c.
Possible problem is that it still has routable parameters (road_class and
road_speed), maybe this causes the crashes? A solution would be to replace all
highway=* & junction=roundabout with a non routable line type on top of this
0x0c for rendering the correct line type. In the default mkgmap style this
problem does not occur because all roundabouts are rendered with the same style
and just one line (0x0c).

I have roundabouts nearly at the front of my home, so I'm routing through it nearly every day (in cycle mode). But I never saw any crash in the near of a roundabout on my GPSMap 62 with my own maps. I think I had this year only one crash of my 62, and here I'm not sure if the fault was not a broken battery.

Re: [mkgmap-dev] Roundabouts causes crashing devices
Hi Minko,
I looked at the recorded GPX tracks now and noticed that the 1st crash happened
while I was approaching one roundabout, I stopped after the rb to switch the
device on again and the 2nd crash happened maybe ten m later aproaching the
next rb. I am not sure about the timing, I just noticed that the device was off
again. I've uploaded the part of the recorded track
http://files.mkgmap.org.uk/download/298/2016-06-29%2006.49.55%20Tag.gpx
The related rb ways:
https://www.openstreetmap.org/way/274709979
and east of it
https://www.openstreetmap.org/way/179620014
Both ways are part of a bus route. Hope this helps.
Gerd

Re: [mkgmap-dev] Roundabouts causes crashing devices
Thanks Gerd, I can't open your track but both roundabouts don't look too complicated with too many nodes and I don't render bus routes, so I think it could be caused with the two routable lines on top of each other in my styles. In the NL's many roundabouts have cycle routes on them I thought at first it was only caused by this routable cycle route line (0x02). After that I have removed this 0x02 I got some positive feedbacks, but now you and someone else also reported it could happen with other roundabouts as well I think other routable lines like 0x06, 0x05 etc on top of 0x0c could crash some devices (not all, at least not mine, which makes it very complicated to reproduce) too...Workaround is to remove all routable lines on top of each other or at least remove the routing parameters (but in the past this lead to other issues with routing via address search).

Re: [mkgmap-dev] Roundabouts causes crashing devices
Thanks Bernd, I think your method of "every routable ways is an invisible line with overlay" will prevent those crashes. With my style I have used in case of roundabouts two routable lines on top of each other that might have caused those occasional crashes. The same with bike routes on top of other roads, I am using line type 0x02 to render dashed lines in all cases on top of other routable lines. Until now I haven't found any non-routable line type that displays on top of every other line. I can make 0x02 unroutable by removing the road parameters but this leads to another issue: When searching for a specific address on that particular road, the device will draw a straight line to that address without using roads. So I either have to accept an occaisonal crash or bad address routing. Don't know what is worse? ___ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
Re: [mkgmap-dev] Roundabouts causes crashing devices
Hi Minko, I#m not completly sure, but I remember, there were long time ago problems with 2 routable lines on same position. So in my map I changed all routeable lines to transparent and used for showing highways etc. non-routable lines. But maybe this particular problem was solved later.

Re: [mkgmap-dev] Roundabouts causes crashing devices
I think that was solved later, however those issues proof it would be better not use more routable lines on top of each other. With some workarounds I have fixed it mostly I hope, but it would be better to use transparent route lines. Which means rebuilding my whole line style and typ file from scratch...
