To analyze road users' preferences for novel service facilities in highway service areas, this study designed 51 service facilities that can or have been installed at highway service areas and employed the Kano two-dimensional quality model as the research instrument. The research findings showed that of the 51 service facilities, 20, 29, and 2 of them were rated as possessing attractive, indifferent, and one-dimensional qualities, respectively; none of them were rated as must-be or reverse quality. A total of 16 key service quality indicators for service areas were identified, with 10, 2, and 4 of them being rated as exhibiting attractive, one-dimensional, and indifferent qualities, respectively. The preferences of road users identified from this study can serve as a reference for service area operators when providing services.
