Urban environments tend to discourage physical activity and participation in physical activity is difficult by many factors, including overcrowding, high-volume traffic, heavy use of motorized transportation, poor air quality, and lack of safe public spaces and recreation/sports facilities. Globally, road traffic injuries are the ninth leading cause of death. Almost half of those who die from road collisions are pedestrians, cyclists, or two-wheel drive users. The objectives of this research were to create a healthy space suitable for increasing physical activity support for everyone in the area along the canal by using Bang Mot Canal as a case study and create a guideline for 1,682 canals and 186 communities in Bangkok. The results of the fundamental analysis with ArcGIS program for spatial analysis due to the factor of an alternative area and the situations showed that the community along the Bang Mot Canal lacked space to support physical activities. Therefore, alternative areas for community healthy space were analyzed. The results of statistical analysis from the opinion of the sample were divided into two groups: local people and outsiders about the healthy space revealed that on average people in the area wanted to have a well-equipped healthy space. The most needed requirements were space, field, and cleanliness. Meanwhile, on average, most outsiders needed healthy space. The most needed requirements are safety, cleanliness, and shade.
