One feature request/bug I was thinking about constantly during my last trip to the alpes:
I think the app should be a little more tolerant/forgiving/forecasting when losing GPS in a situation that can be expected: in tunnels, galleries, underpasses etc. This is especially relevant in northern Italy and southern Switzerland, where they build a lot of roads in so called “gallerias”. They often have nearby towns or local roads and Kurviger is quick to think you’re on one of those instead
Now I don’t think this thread is a duplicate, I know that we already had discussions about rerouting and I know that I could disable it. But let’s assume I don’t want to disable rerouting. I want to talk more about the general sensibility to GPS loss. Most other Navigation devices/apps try to simulate your position and move the marker with an approximate speed inside the tunnel. Kurviger on the other hand is very trigger-happy.
It can have bad results when you want to take an exit directly after a tunnel and almost miss it because Kurviger is super sure that you’re on the road on the other side of the mountain that it jumped to once it lost GPS
I almost missed this exit for example: https://kurv.gr/FSj1S
I don’t know how hard this is to code, but I would really love to have this. Thanks!
One second lemme check… yes, enabled. Oh god, it could have been even worse if I had this disabled?
Nah just kidding, it’s probably no easy task, thanks for recognizing my request
Same experience on my side on my trip to Lago di Garda.
However for me ist really annoying when Kurviger tries to Rerounte several times in tunnels. Turn rerouting off is not an option for me, i like this feature und use it often.
Possiblilities for me here :
Otion to turn Rerouting off in tunnels. This check could be based on OSM Data
Option to use Acceleration Sensor of Handy to determine the speed and Coordinates via OSM Data and then simulate the driving. Several navigation apps do it this way. Its not 100% accurate but it helps a lot.
Would be a very helpful feature even in switzerland and north italy.
I opened this as a new topic to share an idea for kurviger
In tunnels there are different issues, because GPS is lost:
Speed can not be calculated
Junctions can not be found and announced in tunnels and at the end of a tunnel
Speed Limits can not be set, because position is unknown
Suggestion:
Automatic calculation of position and speed based on Accelerometer data of the mobile phone and OSM coordinates. Nearly the same as you do it in Simulation Mode.
The KalmanFilter is very inaccurate, because it only depends on the sensors to find the position.
The position in tunnels can be used from OSM Data and only the speed can be used by sensors.
This would be more accurate.
Would be very helpful in Switzerland and Northern Italy with many tunnels.
Hi. Many times before I wondered how reliable and accurate such data is. Wouldn’t it be easier to assume a constant speed - e.g. 60 km/h when the GPS signal is lost? I know, there may be a traffic jam or some other delay, but will the accelerometer handle such difficulties?
Mit TomTom Go kann man sehr gut auch im Tunnel navigieren. Wie die das machen keine Ahnung aber ich meine hier wird mit der Durchschnittsgeschwindigkeit gearbeitet.
Hatte das Thema Tunnel hier auch schon angesprochen, weil es mit Kurviger unmöglich in Tunneln zu navigieren und es gibt viele Tunnel mit Abfahrten usw.
Die Navigation muss in Tunnels ja nicht akkurat sein, aber zumindest einen groben Anhaltspunkt hätte ich auch gerne. Und bei TomTom geht es ja, habe ich auch schon gehört.
Hallo, ich finde die App echt toll und bin froh eine Alternative zu Sygic gefunden zu haben, was aber echt nervt ist die Navigation durch Tunnels, das navi bleibt dann mit letzter bekannten Geschwindigkeit und Richtung und “fährt” ins Nichts und verliert die Route… Soweit kein Problem, außer du must im Tunnel oder kurz danach abbiegen… Das Navi weiß das ich mich im Tunnel befinde, es kennt auch den Streckenverlauf des Tunnels, wieso also folgt er diesen nicht einfach mit der erlaubten Geschwindigkeit? Andere Navis machen das auch so
You really want tell me that you don’t know where are tunnels? Anyway when you loose the GPS signal, you could following the track until you get a new signal, would be better as to going nowhere…
The information about tunnels is available in OSM data (so you also can see that on several maps).
But for navigation the app uses the information inside the .kurviger file provided by routing algorithm - I do not know if information about tunnels is in that file.
My Garmin Navis extrapolate the position, if GPS signal is lost and according to map data there is a tunnel: They assume that you continue riding on the planned route with the speed measured before loosing GPS signal.
But this is not very precise, especially if you change the speed in the tunnel - and I think the effort for implementing such a feature is high (please keep in mind that the development of the app is a one man show, as far as I know).
Something that could be done more effortlessly is to see from route details
when be in tunnels and temporarily disable automatic rerouting (if enabled).
However, follow user location → turn instructions cannot work without GPS.
Most users do not know it or prefer to forget it.
Maybe we should put a reminder somewhere.
No - it also works on a tunnel curve (Navi assumes that you follow the planned route, and this can also contain a curved tunnel).
Example: Pfändertunnel
