Abstract

The determination of walkability for megacities is critically important, particularly in the context of fostering sustainable urban environments. This paper applies modified Delphi techniques to focus on identifying and prioritizing the key factors influencing urban walkability in large cities. The selected region of the Gulf Cooperation Council (GCC) served as the basis for this research, reflecting its unique socio-cultural and environmental challenges. A panel of local and international experts participated in the study, evaluating and ranking 111 walkability indicators categorized into five groups: cultural, functional, safety, aesthetic, and comfort. Two rounds of the Delphi survey were conducted, to obtain insights from professionals in urban planning, civil engineering, and related fields.
