Even the one that this guy link has some kind of Navteq data (probably just the map). I think the only online maps that don't use Navteq is google (they used to be are now doing it internally).
I'm not sure if this will work, but here is an example:
http://maps.google.com/maps?f=q&sour...08.65,,0,-8.26
That sensor measures congestion and is then sent to Navteq. |
To lazy to type it up myself but this, too.
The company I work for makes traffic data monitoring/recording hardware also but for a much smaller scale. Their system may work of a similar Doppler radar that we use.
