UK National News highlights work at Lund Institute of Technology in Sweden that offers another routing option: greenest. Instead of fastest, most direct or otherwise, the test sat nav devicde tries to find the greenest, that is the route producing the least greenhouse gasses. In tests such routes were more than 8% greener, but scientists say in reality about 4% improvement is likely. Green routes are calculated based on width, speed limits and conjestion on roads.
The challenge is getting good traffic data - the team learned that a single car tracking traffic conjestion as a “probe” does not work well. (I found it odd they didn’t know that already with all the sensor and other technologies now aimed at collecting and distributing traffic data.)
Says a rep from NAVTEQ, which recently acquired Traffic.com:
Making the measurements to give every street in the world a fuel consumption factor will be too expensive.

Action News in Atlanta reports via th AP that those 488 small towns expected to leave the new Department of Transportation map (covered here at APB) will be restored.
Apparently the outcry to both the DOT and the governor had an impact. Maps clearly touch a nerve when your town is not on them!

In a deep comment at Slashgeo, Raj Singh notes:
Check out http://uis.mit.edu/. This is a PostGIS/PHP-based system to allow low-tech organizations do feature attribute editing and basic thematic mapping without having to do any GIS. The research project is at its end and we’re looking for real clients to test the system. Email me if you want to know more.
From what I glean from the site this was part of Singh’s PhD work at MIT and a project about which I heard at NEGIS from Prof. Joseph Ferreira a year or so back.

Ok, well, maybe not all of you, but we [Directions Media] are looking for some interesting people to contribute to our upcoming Location Intelligence Conference April 16-18 in San Francisco (same week as AAG if you are attending that one).
I know from comments posted here and those I receive by e-mail that many forward-looking, creative and opinionated people read APB. They are the types who make conferences interesting by commenting on, challenging and putting forward new ideas.
If that’s you, consider submitting a paper, or offering to be a moderator. And, we’d love for some bloggers and journalists cover the conference. And, of course, we like attendees, too!
