There is a growing demand for mass transportation systems to promote sustainable development due to opportunities for Transit-oriented development, where everything for daily life can be reached within walkable distance. The foundation of sustainable mobility is the integration of mass transportation systems and non-motorized transport. Therefore it is necessary to evaluate the whole environment around mass transit stations to attract pedestrians and cyclists, including the elements such as the street network, sidewalks, cycle lanes, crossings, lighting, signage, etc. Therefore, the need for a more integrated urban environment is necessary. The objective of this study is to investigate the walkability design towards the transit station by taking the case of Al-Mansoura metro station, which serves three most dense neighborhoods in Qatar; Najma, Mansoura and Fareej Bin Durham. The study also includes outdoor thermal comfort of the metro station premises concerning Qatar’s hot and arid climate. After conducting a literature review on the related field, the proposed indicators by Monteiro & Campos (2012), have been modified according to the context of Qatar and used for evaluating the surrounding walkability of Al-Mansoura metro station. The findings include the need for improvement of the physical conditions of the street network and infrastructure for pedestrians and cyclists, and absence of public space within the study area to promote the social welfare of the surrounding neighborhoods.
