With a city growing in size, capacity, density, and intensity, walkability in the Bangkapi district (Bangkok, Thailand) represents a challenge to produce more inclusive transportation through mobility planning that suits the multimodal transportation system (skywalk, MRT lines, water transportation) and the walking experience of the pedestrian. Drawing from Bangkok’s Transit-Oriented Development (TOD) strategic plan, the challenge lies in the balancing point of efficiently and effectively elevating walkability while keeping the local urban identity. This study investigates the notion of walkability as both a ground-up participatory design process and within the overall mobility planning framework by reviewing both Thai and international sidewalk standards and through interviews with stakeholders. We conclude by producing an experimental design guide and policy recommendations on how area-specific sidewalks have the potential in shaping more feasible and equitable mobility planning from the ground up.
