According to the latest report 2019 Revision of World Urbanization Prospects by the United Nations, by 2050, more than two-thirds of the world’s population is expected to live in urban areas or about 6.3 billion people, with close to 90 percent of the increase concentrated in Asia and Africa. Therefore, it is necessary for Thailand to adjust itself wisely, planning and developing effective urban management to cope with such issues. Khon Kaen has been seen as the first smart city in Thailand, starting with the area of smart mobility. It is still being developed at the moment and needs to rely on the conceptual framework and knowledge of policy implementation on smart mobility that has already been developed and implemented in some foreign countries. Taiwan, especially in Taipei, is a showcase of this smart mobility model. The city has recognized expertise in its technological advancements and can efficiently and effectively apply this to urban planning development, particularly in the area of smart mobility. This study conducts documentary research on Smart cities development and collecting information from interviews and opinions of stakeholders that have been published in public media and information from meetings, seminars, and official documents. Thus, this article helps to answer the research question about knowing different ways of development and comparing between the two cities. The results give an insight into factors and components of smart mobility development that allow them to develop in different and same approaches through the Initiatives, Frameworks, Concept of Smart City creation, and Public participation. Also, this article can provide an important way to compare and understand the success of a successful city like Taipei and help cities that are developing smart mobility like Khon Kaen to set the framework for practice and policy.
