The concept of smart cities is gaining interest in the field of urban development. Social inclusion and equality for all citizens are major challenges for smart city architecture. By improving access to the community so the quality of life of mobility impaired people can be improved. Several types of technologies have been proposed to gather necessary information about disability access facilities within a city and provide better accessibility solutions. This paper presents a systematic literature review of some of the technological components which are the building blocks of smart accessibility and a comparison of existing technologies and case studies. A smart city-based system architecture is proposed based on the modification of existing approaches to centralize the accessibility of information and improve the ease of mobility for people with movement disabilities. The proposed architecture gathers and stores disability-related geographical point of interests, provides customized routing services using open source solutions for wheelchair access, and makes the data available for open access.
