Well-Maintained Roadways Improve Fuel Efficiency

CSHub researchers conduct PVI experiment
February 29, 2016

Most people know that properly inflated tires can improve a vehicle’s fuel efficiency, but did you know that properly maintained roadways can improve fuel efficiency across an entire pavement network?

A recent collaboration between the CSHub and the California Department of Transportation (Caltrans) showed that phenomena associated with pavement-vehicle interaction (PVI), including roughness and deflection, accounts for 1 percent of overall fuel consumption on California highways. CSHub models, which examined all of Calfornia's 50,000 lane-mile system, allowed Caltrans engineers to select the paving projects that will have the biggest impact on fuel savings, which will also lead to a reduction in greenhouse gas emissions.

Our research on this topic aims to encourage decision makers to think of infrastructure as part of the solution in a carbon constrained environment.
