Traffic-based driving directions – Microsoft’s clearflow

Mashable reports that Microsoft is introducing a new technology called ‘clearflow’ that calculates driving directions based on current traffic conditions. I will have to try it during rush hour.

They’re using GPS devices to enhance their data sources:

“collecting trip data from…employees who volunteered to carry G.P.S. units in their cars.”

I suggested using mobile phones not too long ago. More sensors equals more accurate data.
