The rise of intelligent cities reflects our increasingly interconnected world. As people everywhere strive for more active and livable neighbourhoods, Jeddah has emerged as a city facing rapid urban growth. Unfortunately, this growth has led to a neglect of walking and cycling transit modes, resulting in a reliance on private cars. To address this issue, our aim is to develop a model for enhancing time-based walkability in Jeddah, using 15-min neighbourhoods as a case study. Our approach draws on a combination of analytical literature review, field study, and case study analysis. By examining the relationship between walkability and pedestrian needs, we hope to design guidelines that improve walking transport within the neighbourhood. To achieve this, we conducted a questionnaire with users, observations and expert interviews to conduct a field study. Our case study focused on two districts in Jeddah, where we explored the proposed time/distance for walkability. Ultimately, we want to create a sustainable, affordable, and practical solution for a hot, arid zone-aligned with the Saudi 2030 vision-that strengthens walkability and enhances the livability of Jeddah's neighbourhoods.
