Summary
This study addresses the challenge of enhancing drivers' intrinsic motivation to utilize a Safe Driving Evaluation System (SDES). Previous iterations of the SDES provided quantitative feedback on driving safety but failed to engage all users, as some participants found the evaluation criteria opaque or unnecessary. The authors hypothesized that improving drivers' active understanding of the system would increase their sense of self-determination and, consequently, their motivation to use the tool. The research aims to validate an improved SDES interface that includes advisory features to clarify evaluation metrics and encourage spontaneous behavioral adaptation. The researchers conducted driving simulator experiments with 18 participants (10 male, 8 female, aged 21–41), divided into two groups. Both groups used a Forward Obstacles Collision Warning System (FOCWS) alongside the SDES. Group 1 used the conventional SDES, which displayed scores for four non-dimensional indices: proper deceleration ($I_F$), deceleration considering following vehicles ($I_B$), stable acceleration/deceleration ($I_A$), and safe inter-vehicular distance ($I_D$). Group 2 used an improved SDES featuring an advisory function. This function allowed drivers to actively request explanations and tips for improving their scores via a switch, providing rational justifications for the evaluations. Participants completed four driving runs on a 12 km course involving pedestrian crossings and varying road conditions. Post-experiment questionnaires assessed understanding, self-determination, and motivation to use the system. The results indicated that while driving performance metrics showed similar improvement rates across both groups, subjective evaluations differed significantly. Participants in Group 2 demonstrated a higher understanding of the SDES evaluation criteria, with statistically significant improvements in understanding scores for the average indices and specifically for $I_D$. A strong positive correlation ($r = 0.86$) was found between self-determination regarding the SDES and the motivation to utilize it, supporting the hypothesis that higher self-determination leads to greater motivation. Furthermore, understanding of the system positively correlated with self-determination ($r = 0.77$). The advisory function effectively eliminated low-understanding outliers present in Group 1, suggesting that active engagement with system explanations enhances comprehension. Additionally, drivers' pre-existing interest and value placed on safe driving positively influenced their self-determination regarding the SDES. The study concludes that incorporating an advisory function that promotes active understanding significantly enhances drivers' self-determination and motivation to use safe driving evaluation systems. By providing clear, accessible explanations for evaluation scores, the improved SDES addresses previous user complaints regarding opacity and lack of necessity. The findings imply that for driving support systems to be effective in encouraging spontaneous behavioral change, they must not only provide feedback but also facilitate the user's understanding of that feedback, thereby fostering a sense of autonomy and competence. This approach is crucial for mitigating risk compensation behaviors and ensuring long-term engagement with safety technologies.
