Make Tunnels navigable

Kalmann filters are already the core of navigation and positiong apps and systems :)
Realistically the way to do this is inertial guidance when gps is lost but as time since gps loss increases it will obviously become less accurate.
Clamping to planned route at last known speed is realistically all that might be possible without other external data sources.

Under review since 2011?

My idea of making tunnels navigable is not by using external sensors located into the tunnel which will be impossible to be broad applied and expensive. Instead the idea is to use sensors of mobile phone with simple calculation by interpolation of actual speed at the entrance focr example. Any other idea is welcome.I saw this function working on Sygic and it's fine

You could use accelerometers and gyroscopes to suppliment GPS data. Use accelerometers and gyroscopes to increase accuracy of location with with virtually no power increase. It would also allow navigation through tunnels and such when GPS location is lost. It would also prevent erroneous movement while stopped at a traffic light. There are companies testing this type of technology. One that I have been following but have no financial interest in is navisens.com There are videos from navisens at https://www.youtube.com/user/navisens

Please close this suggestion. Waze have the solution.

Please put in the bluetooth-GPS transmitters into the Detroit-Windsor Tunnel, so that WAZE will work within that International Tunnel. Also warn when approaching or mapping this tunnel that you must have passports, and/or Enhanced Driver License to get in and out!

Use Kalman filtering combination of GPS, accelerometers, etc to do dead reckoning. Even without that, you can guess the speed in the tunnel from the speed before and after the tunnel.

I back this idea up as well, when entering a tunnel, the location just goes nuts. it should be possible to interpolate the position on the current route and show the next instruction

Exactly what Waze needs, and maybe the only thing it needs.

Had a TomTom 7 years ago that kept my average speed when entering the tunnel. It's nothing new really.
But yeah bluetooth Obd2 support would be awesome. -

When you drive in a tunnel Waze stop the navigation. Please make that Waze drive whitout signal to the next instruction at the same speed that the way.
Thanks -

I thought Waze already used accelerometer data to accomplish this, but then everytime I enter a tunnel, it just pauses. This is easily corrected.

In London, there is a tunnel which forks underground. No satnav, WAZE included can get a GPS signal.
It would be useful if Waze could give directions ahead of time when you approach an area or stretch of raod (eg a tunnel) where it knows (from prior users' experience) that it is certain or likely to lose signal.
Additionally, or alternatively, there could be an user-selected option where, when signal is lost, Waze either a) considers the car to have stopped, or b) considers that the car is continuing at the same average speed as just before signal was lost.

This idea was exhibited in Brazil in the first meeting of wazers
This was my presentation http://www.slideshare.net/alvtej/waze-rio
Go to Slide 19. -

Dead reaching could be used when in tunnels.

There is one very big issue with this. How does the app track your progress in a tunnel?? The app, like all navigation apps, use the signals from GPS satellites to work out where you are. These signals are not able to reach your phone/tablet whilst you are in a tunnel. Try listening to a radio station in a tunnel and see. How about phoning someone? "opps! sorry, entering a tunnel, losing the sig........"!

I've been stuck on my way to Paris on the A14 tunnel for nearly 1h30. It took me 2h30 while waze suggested 1h for my total trip !
This was the worst suggestion ever.
I don't understand why I didn't get any update from the app since I was able to get mobile network without any problem. A fix is needed urgently for this major issue IMO. I can"t imagine that Waze doesn't see when we get in and when we get out the tunnel. -

Yes, Waze reads the suggestions. Check the Wishlist here : https://wiki.waze.com/wiki/Wishlist

Navigon / Garmin has a tunnel navigation mode and Waze really needs one too. Especially where you have tunnels - like where I am in Stockholm - as here, we have multiple splits and exits inside tunnels.

Nicolas Bougues has a great suggestion. Waze's inability to extrapolate tunnel conditions leads to bad routing recommendations relating to them (e.g. every time I go through the Boston Central Artery Tunnel my estimated arrival time improves by five minutes as soon as I exit. Also, it's not uncommon to get poor route recommendations because Waze believes that there's significant congestion - frequently routes involve getting off the highway, taking local roads and then getting back on OR driving to a distant highway entrance for no particular reason).
