However the software, as I understand it, already exists, it's just not part of OSM.
Any use of an algorithm like this is going to be the same whether your measuring time or distance I notice Google maps has a very similar tool, but only in the US (which is why I didn't mention it) and only as an overlay (doesn't use during routing). In fact I'd already seen a similar thing for the UK on, I think, the highways agency website. Both limited themselves to motorways though. There's also a traffic system on Microsoft live maps but either they've removed it or it's only accessible to US visitors. This NY Times article discusses their methods and they're similar to what I proposed http://www.nytimes.com/2008/04/10/technology/10maps.html?_r=1&oref=slogin __________________________________________________________ Sent from Yahoo!
