In 2001, the crash of a wheelchair lift sparked a debate on the right of mobility for persons with disabilities. More than 20 years have passed since then, but the right to mobility of persons with disabilities is still in a state of being answered. Meanwhile, the technologies and services that can make mobility more convenient have improved significantly over the same period. However, the development of technology without a welfare perspective raises the problem of alienating persons with disabilities, who are the greatest beneficiaries of such technology and services. Looking at the current state of transportation mobility for persons with disabilities, the introduction rate of low-floor buses by the end of 2021 remains at 27.8%. Mobility for intercity travel is even worse, with few low-floor intercity or highway buses, and even call taxis for persons with disabilities, are troublesome to use. This is due fundamentally to the current legal position that treats disability as a physical problem solely for the individual. Besides the lack of public awareness of persons with disabilities and their right to mobility, difficulty in developing technology for persons with disabilities can be brought up as a secondary problem. Therefore, the responses are required that new provisions prohibiting discrimination against persons with disabilities in the Constitution, amendments to legal provisions regarding disabilities and persons with disabilities, education to low-floor bus drivers, development, popularisation of mobility equipment based on universal design, and participation of persons with disabilities in policy-making.
