The digitalization of urban public transportation services becoming increasingly. Rapidly iterative intelligent applications and complex operating procedures have put forward higher requirements on cognitive level and increased learning costs of users, and people with disabilities face more impacts, difficulties and challenges during travel. It is hoped that the first-hand information about the travel of people with disabilities can be obtained through research, which can provide basic data support for future research. Based on the subject research of China Disabled Persons’ Federation, through field follow-up researchs and in-depth interviews of 13 people with disabilities and data analysis of 280 research questionnaire samples, from the perspective of travel experience, adopt a combination of qualitative and quantitative research methods, study the travel lifestyle of people with disabilities and the application of assistive technology, and sort out their travel needs and obstacles and pain points in the travel process. The concept and path of barrier-free travel construction facing the future are proposed, combined with assistive technology and barrier-free design to expand the travel margins of people with disabilities, to promote people with disabilities to participate travelling on public transport more equitably, and to share the "life benefits " of the digital age.
