Summary
This study investigates the efficacy of two eco-driving training methods—traditional instructional videos versus an interactive guidance system—within a driving simulator. The research addresses the challenge of teaching drivers to reduce fuel consumption and CO2 emissions without compromising safety or causing distraction. While previous studies indicated that full instructor-led training yields better results than theoretical learning alone, such methods are resource-intensive. The authors aimed to validate a self-guided digital educational tool based on the Cognitive Theory of Multimedia Learning, specifically utilizing cueing and feedback principles to enhance procedural skill acquisition while minimizing cognitive load. The experiment involved 72 licensed participants randomly assigned to three groups: a Guided Video group (GVg) receiving videos plus real-time interactive feedback, a Non-Guided Video group (NGVg) receiving videos only, and a Control group (Cog) receiving neither. Participants completed four driving scenarios in a fixed-base simulator equipped with eye-tracking technology. The design included a pre-test, two training sessions, and a post-test. The interactive guidance system provided visual and auditory cues regarding gear changes, speed maintenance, and deceleration techniques, offering immediate feedback on CO2 emissions and rule compliance. Safety metrics, including lateral control and time headway, were monitored alongside eye-movement patterns to assess distraction. Results demonstrated that both experimental groups significantly reduced CO2 emissions compared to the control group, which showed no improvement. The GVg achieved a greater reduction in emissions than the NGVg, with the interactive guidance system contributing an additional 5% improvement in eco-driving performance beyond video instruction alone. Crucially, the study found no negative impact on safety; the GVg maintained safety scores comparable to the other groups. Eye-tracking analysis supported the theoretical framework, revealing that participants in the GVg had fewer fixations and spent less cumulative time looking at the dashboard, indicating that the cueing system effectively reduced visual search effort and extraneous cognitive processing. The findings confirm that interactive guidance systems based on multimedia learning principles are effective tools for teaching eco-driving behaviors autonomously. The study establishes that such systems can enhance fuel efficiency and reduce emissions more effectively than video instruction alone, without increasing driver distraction or compromising safety. This supports the integration of real-time feedback mechanisms in driver training programs, offering a scalable alternative to instructor-led training that facilitates the transfer of procedural knowledge into practical driving skills.
