I was intrigued by the different colours on Google Maps in the car re traffic. Googled and found this. Thought if anyone was not aware they may find if of interest:
Google Maps will either show current colour-coded traffic conditions on motorways and roads where data is available or display a message to say that data is unavailable.
  • Green: more than 50 miles per hour or 80 kilometers per hour
  • Yellow: 25 - 50 miles per hour or 40 - 80 kilometers per hour
  • Red: less than 25 miles per hour or 40 kilometers per hour
  • Red/black: very slow, stop-and-go traffic
  • Grey: no data currently available

This doesn't make sense as it shows green on roads with 30mph limits (where the data is available)
 
You are right. I think somewhere else it says for slower roads green is top speed for that limit

Yeah, I guess that works because the sat nav is aware of the speed limits. Good find though, will be interesting for motorways. :)
 
The colours on the audi nav aren't necessarily the same. They get their traffic data from the same source as Google, but not google themselves, and I imagine Audi would be free to choose its own colours anyway.
 
Thanks for the discussion above.
I put my first post prior to getting in the car.
I have looked at the colours both when I have a destination in action and not.
I have not worked out the colour coding yet....
I guess the traffic speed in town will depend how many people have their phones transmitting speed data up to the cloud.
I guess more likely in London that in the sticks..
I like the way that roadworks are identified...
Onwards and upwards

Actually some traffic monitoring services use phones without GPS and data - cell towers can track where phones are, and if you correlate movement with road positions it can give you information on traffic too.
 
Is there any emperical evidence, that

RDS-TMC Traffic Information is better than Google Traffic
or
Google Traffic is better than RDS-TMC?

Both use INRIX, INRIX owns ITIS Holdings, both use crowd-sourcing data, both have fleet based floating vehicle data. In fact I'm pretty sure that 95% or better of the data is identical, yet, there is heresay that Audi Connect (because it gives you Google Traffic) is better for traffic, than RDS-TMC.

I personally think that both use the same data, so have identical performance!
 
I don't know where this thing that connect gives you google traffic is coming from. It gives you INRIX traffic!

The INRIX data has more information, length of delay, how much of a delay there is (colour coding), how far the slow traffic extends, etc. From what I've seen of the TMC, it just gives you single locations and a short description and that's it. You can't have them displayed on the map either as the coloured lines AFAIK.
 
RDS-TMC also (in the 8V with Tech Pack, without Connect)

Gives you length of delay (in time and miles)
Distance of delay
And can show it on your route (map display) if you have programmed in a destination, and is on your route

But it doesn't display the various coloured lines for the surrounding area, no.
 
Many thanks for the information.
Very much appreciated
Phil

Has anyone found a web link to explain the colour coding yet? Still can't work it out
 
Green = good
Yellow = bad
Red = really bad

Thanks, but sometimes, for example at complex Motorway intersections, roads which you could or would never go down are red...
