New academic study underscores CoPIRG finding on reduced driving

A new report from the University of Michigan Transportation Research Institute indicates that light duty miles down 8.8% between 2004 and 2011.

New academic report out today (link goes to PDF) on reduced drive of light-duty vehicles (not heavy trucks, buses or motorcycles) examines how vehicle miles travelled have fallen based on  rates per person, per licensed driver, per household, and per registered light-duty vehicle. Since CoPIRG’s analysis has included truck and bus travel these numbers are a little bigger than ours. Between 2004 and 2011, light duty miles fell 8.8% per person and slightly more per household or per registered vehicle.

These trends should not be ignored by Colorado planning officials.
