Denver thinks giving drivers information about their present driving patterns can help change their future driving habits. The city is in the second of a 9-month pilot program, Driving Change, equipping 400 cars with an electronic system to track carbon dioxide emission. Instead of using an in-car dashboard, drivers log onto a web site to see their green stats (though presumably they could do this in their car if they have a wireless broadband card).
The primary goal of the pilot is to produce up to a 20% reduction in CO2 from each pilot vehicle…or up to 4 to 5 miles per gallon in increased fuel efficiency.
The online dashboard will also allow drivers to see their estimate fuel efficiency and trends in their driving behavior (such as fast breaking, engine idling, and speeding). Participants are able to use the dashboard to compare their performance against a baseline standard, and against other drivers.
