I wanted to make sure folks on this listserv are aware of our "37 Billion Mile Data Challenge" which should be of interest to researchers, modelers, and transportation planners across the country. Individuals, academics, teams, and companies are all welcomed and encouraged to participate. Visit www.37billionmilechallenge.org<http://www.37billionmilechallenge.org> for complete details. MAPC just launched a 6-week data challenge to help unearth the lessons to be found in an unprecedented new dataset about vehicle ownership and usage. The Massachusetts Vehicle Census contains anonymized information about the make, model, age, estimated mileage, fuel efficiency, and zip code of every passenger and commercial vehicle registered in the state from 2008 to 2011 AND a spatial dataset of 250 meter grid cells with statistics on number of vehicles, vehicles per household, mileage per vehicle, and greenhouse gas emissions. Few researchers have ever had access to this type of information and we are opening the doors to everyone who wants to try their hand at making a beautiful visualization, an insightful analysis, or a useful tool out of this big data. In particular, we're looking for submissions that will help guide the actions that the state and its communities are taking to build a more sustainable transportation system. Judges include the Massachusetts Secretary of Transportation and the public, who will be able to vote for their favorites online. Winners will walk away with cash prizes and recognition from the Commonwealth. Visit www.37billionmilechallenge.org<http://www.37billionmilechallenge.org/> to learn more or follow along on twitter @37billionmiles. Challenge closes on April 19. ___________________________________ Timothy G.
