When GPS or data reception is poor, Waze starts crazy and irrelevant navigation instead of stopping and declaring a problem.

Driving in from the western suburbs to downtown Chicago, it loves to use Lower Wacker Drive and then turn onto Lower Michigan avenue. This is kind of great, except you're pretty much on your own once in the tunnel and Android Auto is trying to keep things simple and you can't really look at the next turns, like I can if I unplug. Generally, on emerging, there's a period where things are very confused, and the next few turns are kind of crucial, and suddenly very crowded, so it will drop you in the middle of crowdedness multiple lanes, and then give you bad advice long enough to where you're committed to going one way and really should have gone the opposite way. (For example, tell you to turn left, and you get in the left lane and it switches you to turn right and you're never going to recover in time).

However, if I had a list of turns that would come up on entering the tunnel and a turn or two after it for a bit as the GPS gets more solid, it would help immensely.

...continue traveling with the last speed before loosing GPS signal.

When we enter a tunnel, we usually lose the GPS signal and, as you go through the tunnel, sometimes and for a brief moment we can get a GPS signal again (for example, near an emergency exit), thus being able to obtain the current position of our vehicle inside the tunnel.

But when this happens in an urban tunnel, the normal thing is that on the surface there are streets, pedestrian zones, etc. and then, Waze goes 'crazy' and thinks that we are on that street instead of the tunnel, which causes a recalculation of the wrong route.

My proposal is that, since Waze knows that we enter a tunnel and what the outputs are, just recalculate the route when it detects that we are leaving the tunnel through one of them.

Implement continuous navigation, even when a navigation device can’t receive GPS satellite signals (e.g. in tunnels) using movement and gravity sensors. TomTom has Enhanced Positioning Technology which allows continuous navigation in tunnels.

If possible i would like to chat to someone in regards to improving connectivity for GPS when in tunnels. we have a patent helical antenna that is used at mines (tunnels) and ca be used also in tunnels

When GPS reception is poor, Waze could be more intelligent:
Have I really just hopped to a side road doing 70mph?
Have I just turned off the road doing significantly more speed than a car can corner?
When going through a long tunnel have I just stopped in the middle of the road?

Surely the app could work out given the accuracy of error and my previous road that I am still travelling on that road at the same speed?
It should be able to work out what the possible scenarios are and score them for probability?
And when I lose signal, e.g. going through a long tunnel why doesn't it just assume my previous speed, i.e. continue on my planned route at my current speed? Surely that is better than just stopping? Even TomTom used to do that on my iPAQ!

I walk through roads with numerous galleries and logically the GPS signal is lost. It would be convenient to develop the app to continue traveling virtually until the new GPS satellites are hooked.

Ihre App ist sehr gelungen. Es gibt bloß eins was sie vllt mit dem nächsten Update vllt verbessern sollten. Und das wäre, dass man die GPS Simulation im Tunnel aktivieren sollte. Dort bleibt immer der Punkt stehen wo er kein GPS hat. Andere Programme wie Google Maps nutzen diese GPS Simulation schon. Wäre ne super Aktualisierung für ihr sensations Navigation System.

Hello,

I find your application very well.

It would be perfect if:

- GPS navigation continued to advance when in a tunnel (act as if the vehicle is theoretically up to speed limiting).

- you get to fix the bug preventing the handsfree phone kit from working at the same time as Waze.

If you manage to correct these two cases, Waze would be almost perfect.

Bonjour, 

Je trouve votre application très bien. 

Elle serait parfaite si :

- la navigation GPS continuait d'avancer lorsqu'on est dans un tunnel (faire comme si le véhicule avancé théoriquement à la limitation de vitesse en vigueur). 

- vous arrivez à corriger le bug empêchant le kit main libre téléphone de fonctionner en même temps que Waze. 

Si vous arrivez à corriger ces deux cas, Waze serait quasi parfait. 

Cordialement 

When I am waiting under a road light between two 10 story building then the GPS signal strength gets weaken and Waze thinks "I have made a U-turn, than back, then turned left, no, right".

Waze should use the built in compass, before such event deduction to be sure. Or simply know that it is impossible to "make a U-turn, than left, then right" in 1 second.

Generalmente en los túneles el GPS no recibe señal, por lo mismo Waze queda con la ultima posición del móvil que al "no moverse" genera información de trafico denso sin que efectivamente sea así en muchas ocasiones. Al marcar zonas de la Via como TUNEL, Waze podría "ignorar" esa detención virtual y no mostrar la ruta como congestionada, o bien si se puede detectar que el GPS perdio señal y asi no considerar esa info para trafico.
