I'm not sure if this kind of data should directly be in the OSM database, but probably in a secondary database.
There is an unfortunately named thread on OSM-dev ([Fwd: Mail delivery failed: returning message to sender]) [1] about a company interested in providing just this sort of data: "We'll be logging this data and producing average [speed] data for each road way a vehicle travels down, and keeping separate profiles for different types of vehicles, dates and times." -Josh [1]: http://www.mail-archive.com/[email protected]/msg14406.html On Tue, Apr 5, 2011 at 2:01 PM, Jay Mahadeokar <[email protected]> wrote: > Hi all, > > I am Jay Mahadeokar, doing Masters in CSE from IIT Kanpur, India.
