This study conducted a six-month naturalistic driving experiment with 15 participants to analyze the impact of eco-driving on fuel consumption using data collected via the OSeven smartphone application. In the first four months, participants drove as they normally would, followed by two months of eco-driving. Preliminary analysis using R Studio showed a reduction of harsh accelerations and harsh braking by 3.79% and 27.42%, respectively, and 8.14% in fuel consumption. Log-normal regression models developed to study the relationship between driving behavior and fuel consumption indicated that smoother driving styles, characterized by gentle acceleration and deceleration, are associated with lower fuel consumption. Other factors, including the vehicle’s age and driver’s adherence to speed limits, also influenced fuel efficiency. The study provides valuable insights into promoting eco-driving practices, suggesting future research directions to explore the nuanced effects of different driving behaviors on fuel consumption.
