Abstract:This study tested the impact of continuous miles per gallon (MPG) feedback on driving
behavior and fuel efficiency in gas-powered cars. We compared an experimental condition,
where drivers received real-time MPG feedback and a tip sheet, to a control condition
without such feedback at the time the experimental participants received it. We had three
study aims:
Aim 1 was to modify the fuel efficiency obtained while driving gas-powered cars. We
specifically hypothesized that mean MPG would be greater in the experimental compared to
the control condition during the intervention period, and this difference would be maintained
during the return-to-baseline period.
Aim 2 was to modify the driving behaviors of drivers of gas-powered cars. Our hypothesis
was that participants in the experimental compared to the control condition would report
engaging in more fuel efficient driving behaviors during the intervention period, and this
difference would be maintained during the return-to-baseline period.
Aim 3 was to explore ways to improve the feedback display among users.
