Abstract
Much research has been done on evaluating recreation benefits by travel cost method. Many of them applied for comparatively large recreation sites which the visitors come from wide range around there. On the other hand, there are many small sites that only the neighbors visit. Because almost visitors for small recreation site are on foot, the factors which visitors decide to visit there are more regional and spatial than large one. This paper suggests incorporating regional and spatial data in travel cost method contribute to evaluate the benefit of small recreation sites. For the purpose, many regional and spatial data were generated by GIS for two areas around reservoirs in Osaka prefecture.
