Abstract

This study aimed to enhance the safety of school buses by investigating user satisfaction and analyzing the prioritization of vehicle safety devices using the KANO model and Timko’s customer satisfaction coefficients. The results of the user experience-based satisfaction survey indicated a high overall satisfaction level, with particularly positive evaluations of safety-related devices. However, some respondents expressed concerns regarding the narrowness of seat specifications and legroom. To examine the relationship between satisfaction scores and demographic characteristics (gender, grade, and Use of existing school bus), random forest and chi-squared analyses were conducted, revealing significant factors affecting satisfaction scores. Subsequently, a KANO model analysis was performed to derive the prioritization of additional vehicle devices for improving the safety of school buses. Among the eight vehicle safety devices analyzed through the KANO model, some were categorized as One-dimensional quality, while others were classified as Attractive quality. The prioritization of safety devices was further established using Timko’s customer satisfaction coefficients. The findings of this study are expected to contribute valuable insights for the commercialization of technologies aimed at improving the safety of school buses in the future.
