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.
Challenge closes on April 19.
