App: Display speed limit

Thank you for your response.
I apologize for my English.

I tried “Tempomaster”, but the database is only available in a few countries.
And I’m from the Czech Republic.
And my country is not in this database.

So I searched intensively further and this morning I found the right application.
That application is called TomTom AmiGO

I tried the application in the afternoon and it works very well.
Accuracy approx. 90%
But I was not in a big city.
I’m going to the big city on Monday, but I believe it will work well.
This application is developed by the navigation manufacturer TomTom.
So it contains their database of speed limits.
It’s free, so you can try it. The downside is that the application must be online.
It also contains a database of speed cameras, but it is not very accurate.
Many speed cameras are missing in this database. Maybe just for my country.

I use Radarbot Pro to warn of speed cameras.
It’s a paid application, but I can recommend it to you.
Huge database in many EU countries.
It is also in the Free version, but it does not include the overlay display function.

And both applications can be turned on automatically using a bluetooth device. That’s great. :ok_hand:

TomTom AmiGO: The maximum speed on the motorway in this section is 130 km/h
Radarbot Pro: Indicates that in 882m there will be a speed camera with a maximum speed of 80 km/h

It also shows very slow limits:

You can try it!

Enjoy but wheels down! :+1:

Tomtom Amigo requires sharing and reuse of location and route data. This is completely unacceptable to me. App immediately deleted again.

App permissions of Radarbot Pro are also too comprehensive for me.

Oha, navigation and speed Infos without location and routing data. Interesting …

That’s not the point at all. If the data were kept locally on the smartphone or not stored in the first place, that would be perfectly fine. But this typical sarcastic remark ignores the fact that by using the app, you have to agree that the location and routing data will be used for analysis purposes and passed on to third parties.
Anyone who doesn’t care about their personal data is welcome to do so. For me, however, this is completely unacceptable.

Yes, it is your freedom of choice.
According to the statement, the shared data is anonymized.
You can disable this data collection option in the AmiGO settings.

How the app with handle the speed limit information?

There will be an extra panel displaying the current speed limit.

When exceed the speed limit, some warnings could be useful?

  • Screen alert
  • Sound alert (voice prompt or alarm tone?)
  • Adjustable speed limit tolerance for the alerts

Today I had a 400-km-ride (my easteregg tour):
I often saw the questionmark instead of a speed limit. And even more often a total wrong speed limit. My feeling: approximately half of the OSM contents regarding speed limit is not correct!
Hopefully we don’t have to expect a lot of complains …


All of these warnings can be useful.
Many users = many options.
But the important thing is to allow the user to control options - on / off
I prefer a alarm tone for the sound alert.

Same here.
Me I preferred a screen alert: Won’t be frequently disturbed by a tone, as expected because of the many wrong data about speed limits in the maps.

OpenStreetMap Wiki mentions:

“The maximum fixed numeric speed limit, followed by the appropriate unit if not measured in km/h when no units should be included. For example maxspeed=60 for 60 km/h and maxspeed=50 mph for 50 mph (note the space between the value and the unit).”

For example in London there are ways where maxspeed has a text “20 mph”.
Kurviger (GraphHopper) conveniently returns maxspeed as number 30 (km/h).

So it should be fine to interpret everywhere the maxspeed as number km/h?
(and convert to mph, if app uses imperial units)

Available for testing in Kurviger 2.0.7 (Beta).


ich habe mir gestern die Beta 2.0.7 runtergeladen um das Tempolimit zu testen. Sollte das funktionieren, ist die App für mich fast perfekt. Nur habe ich keine Anzeige der Geschwindigkeit gesehen. Ich bin online/offline gefahren, habe mit der Toleranz des Tempolimits gespielt (von -10 bis 20km/h) aber nichts ist passiert/wurde mir angezeigt. Hat das schon jemand zum laufen gebracht?


  • The speed limit display (with screen alert) is available in “Settings | Navigation | Speed limit”.

The speed limit display is the 4th right panel. The speed limit screen alert is the red circle.

  • The speed limit tolerance can be adjusted in “Settings | Navigation | Speed limit tolerance”.

  • The speed limit voice alert is available in “Settings | Voice guidance | Speed limit”.

(BRouter does not currently provide speed limits)

Kurviger speed limits are derived from OpenStreetMap data (where available).
Please provide some route example, so we can see if it contains speed limits.

Ok, great. The only thing left is the distance to the next or 2 next gas stations. And then everything is how it should be :grinning:

Speed limit tolerance is great. I would propose 2 limits, one for inner-city and one for outside town.

There is no city separation in route data and navigation.

OK thanks for information, no problem. The speed tolerance maximum at the moment is 20. Is it possible to make it up to 40?

I think the warning to exceed the speed of the road is for this: you know that you are going above and I do not think that you need to activate the message when you go to +40 km/h above.
In my config I set it to 5 km, enough to avoid a possible radar. :wink:


Yes I do, that’s exactly what I ask for. Otherwise I wouldn’t have asked. I prefer a warning only when I am far too fast, not when I am a bit too fast. Same was possible in Navigon and Navigon Cruiser .

Sorry but this is BS. A warning at 40 above because then you lose you driving licence or? I think there are more important improvements to be realised, like distance to the next 2 gas stations on the route. My thought.
