In this research, we propose an evaluation method for walkability by dividing the road space into various components and assigning a walkability score based on both the physical conditions and the experts’ opinion using the Analytic Hierarchy Process (AHP). Using the walkability score, we visualize and quantify the existing problems. The visualization allows us to determine both the structural problems in the walking environment and the critical factors affecting walkability. This research is carried out with the cooperation of  Kasetsart University, Thailand.
