Rapid urbanization in cities has increased children's exposure to unequal urban conditions. Nevertheless, the concept of school commuting has not been recognized as a part of the role of urban vulnerability in the well-being of children. This paper hypothesizes the development of an integrative model between the city vulnerability, commute satisfaction, and the well being of school children with Kuala Lumpur as the case study. As the study is based on the ecological systems theory, which is informed by the Socio-Ecological Model (SEM) by Bronfenbrenner (1979) and the Mobility-Well-being Model (MWM) of De Vos et al. (2013), the conceptualization of the urban vulnerability is grounded in the multidimensional nature of this phenomenon, which is influenced by environmental, social, and financial factors that influence the daily mobility of children. It asserts commute satisfaction; according to the perceptions that the children of the city have towards safety, comfort, reliability and emotional experience that has a mediating role on the relationship between the vulnerability of the city and the well-being of kids. Through an emphasis on the school commute as a daily but not unimportant zone of child-city interaction, the study presents a child-specific perspective on metropolitan inequality that transcends the context of the household and school. This project will use Structural Equation Model (SEM) to discuss the response and outcomes using a quantitative design. The framework states the testable hypotheses and provides Kuala Lumpur as a model of a high-growth urbanisation city, where mobility availability is not evenly distributed. This research is relevant to urban transport research and child well-being research by establishing school commuting as an important concern in urban policy that addresses children in a way that is both equal and child-centered.
