Abstract
This paper aims to clarify which characteristics influence the number of urban park visitors. The study employs a residual analysis as a heuristic approach, which is a useful approach to choose explanatory variables effectively. In fact these characteristics are difficult to identify among numerous related variables, and a big residual value may involve the significant factor. The results reveal five major factors to have influences on the number of park visitors in concern: 1) population living in park's service distance; 2) volume of tall trees; 3) number of simple amusement equipment/facilities; 4) width of streets facing to a park; and 5) park elevation relative to surrounding road level. In addition, it was found that a block park has a service distance of 250 to 350 meters.
