The purpose of this research is the development of a model for locating spatial function in human space based on patterns of individual use of spatial function considering the frequency of use and the exclusive character on space. In the model, every individual use of spatial function results in items, which has its own scale in real space. Using this model, we discuss the relation of the accessibility and spatial location of functions. We also analyze the problem of individual trade-off between the increase and decrease in accessibility when one function is jointly used.
