For human beings, freedom of movement and the right to move are very important in realizing their basic rights. In particular, the task of securing the right to move is recognized as important not only for the person with disabilities, but also for the transportation-disabled people who have difficulty in moving, such as the elderly and pregnant women. For the transportation vulnerable, securing the right to move is a functional element that enables life as a social part of life. On the other hand, autonomous vehicles can expect freedom from movement for the transportation vulnerable in terms of ‘mobility’ as a futuristic vehicle. However, facilities for realizing the widespread and universal use of autonomous vehicles have not been established. In addition, there is no significant change in society's perception, system, and policy regarding this. Therefore, this study used the KANO model analysis technique to review the functional priorities for autonomous driving-based future mobility services for the wheelchairs users and analyzed the results. Through this, it was possible to confirm the technical preference priority for the requirements of the wheelchair users. The results of applying the KANO model are as follows. Among the 31 quality evaluation item elements, 15 items of one- dimensional quality factor, 13 items of attractive quality factor, 2 items of indifferent quality factor, and 1 item of must-be quality factor were derived. And the five priority based on PCSI according to the definition of requirements of wheelchair users are as follows. ⑴ Text message reception function (date of use, destination, vehicle number, etc.), ⑵ cancel reservations in the app, ⑶ user recognition function in vehicle(sensor, voice, keypad, NFC method, etc.), ⑷ control center connection function in case of unexpected situation in vehicle(voice recognition based), ⑸ reservation change function available in the app(time, route). Therefore, this study confirms the functional requirements of wheelchair users in the development of mobility service technology for the transportation vulnerable in traffic using Lv.4+ autonomous driving technology. And by examining the functional priorities, it is expected to contribute to the success of autonomous driving technology development for special transportation services in the future.
