Effectiveness of Static and Dynamic Eco-Driving Information

Eco-driving describes adjustments to driving behaviors that drivers make in order to improve vehicle fuel economy. Many drivers do not employ eco-driving practices due to a lack of knowledge of such driving methods. This study seeks to understand the effectiveness of informing drivers of eco-driving tips via information pamphlet (static eco-driving information) versus exposing drivers to an in-vehicle device that provides real-time fuel economy feedback (dynamic eco-driving information). Participants in the study drove their own vehicles on a predetermined route twice with a device connected to their vehicles for collecting second-by-second driving and fuel consumption data. The route included residential streets, commercial roads, and freeway segments. The first drive of this route by each participant was considered the control and established the driver’s normal driving habits and fuel economy that resulted from their driving patterns. For the second drive, participants were split up into two groups. The first group was considered a static group, in which drivers were given the static eco-driving information. The second group was a dynamic group, in which drivers had access to the dynamic eco-driving information. Results demonstrate that both methods of presenting eco-driving information had a positive effect on gas mileage. 13 of 20 participants (65%) in the static group and 30 of 44 participants (68%) of the dynamic group increased their gas mileage after being introduced to the eco-driving information. Participants in the static group experienced a 6.4% average increase in miles per gallon while those in the dynamic group experienced an average increase of 3.4%. In addition, drivers participating in the study averaged about 4% higher fuel economy than the Environmental Protection Agency (EPA) estimated fuel economy ratings for their vehicles.
