Make Tunnels navigable
Great news! The Waze Beacons Program is in the works and constantly expanding.
The Waze Beacons Program is the first scalable, affordable solution in the world to power navigation in tunnels. Currently available in select tunnels throughout Pittsburgh, Haifa, Israel, Paris and Rio de Janeiro – seamless navigation is available to Wazers underground simply by turning on Bluetooth functionality.
External sensors are crap. Pls. use the gyro. The technology is old as instrument flying. In former times the gyro costs millions, now we have then for "free" and we are talking about 25 sensors per km... Bad business! Nobody will be so stupid to install THAT (I hope so at least...)
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.

Would it be possible to use the car speedometer to do dead recknoning when using waze with android auto?

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

I also agree. It is good to see what is behind the tunnel. Navigation has to remember actual/maximum speed and show calculated position.
Fg if I have to turn away from road directly behind the tunnel I have to move map manually. It is not so comfortable, maybe also dangerous.

Please close this suggestion. Waze have the solution.

Sygic navigation navigates through tunnels at the last known speed. If you change the speed until you get the GPS signal again, the pointer simply jumps forward or backward. Simple and effective.
I agree. i had exactly same idea. and why not doing in tunnels exactly like if the signal would be received: navigation should continue at the legal speed or at the speed driver had while entering the tunnel. So it would show the way. And then stop the image at the next "decision point".
Please implement this option in the next update.
Instead of searching for complex and expensive bluetooth solutions like i saw on the news...
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.
Double-integrating the accelerometer to calculate position will always cause accumulating error in the estimate, but Kalman filtering combined with the GPS would eliminate as much as possible. Location will be much more accurate and it will no longer mistakenly think that I'm still on a highway when I've taken an exit and am driving along the service road, and can guess how far through a tunnel I've traveled, etc.

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.

The Bluetooth OBD dongle TomTom LINK 100 can real time stream the actual speed of the car, especially in tunnels, in traffic jams and at road intersections. Allianz France has incorporated that dongle, the TomTom LINK 100 SDK into its Conduite Connectée app. Waze could consider teaming with TomTom on that, at least on a pilot market. Why not ?
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.
It would be already great if Waze was able to take tunnel traffic conditions into account, based on average speed to go through it? I have a long tunnel in my daily commute and the lack of information on the traffic status inside the tunnel often results in long queues that could be avoided.
Average speed between two known positions based on GPS data should not be a major deal?

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