Abstract This study aims to identify the Edge Effect that has not yet been considered when allocating public facilities and analyze its impacts on accessibility. The “Edge effect” refers to the idea that there may be interaction between adjacent boundaries to reach the nearest facilities and services. Based on the optimal locations theory, the research was conducted by comparing two boundaries between the administrative and the theoretical Voronoi diagram. The results, firstly, show that the effect of reallocation of population density caused by the theoretical diagram leads to a change in facility density and secondly, the efficiency and optimization of the facility network has come to be different between the two boundaries. There may be difficulties in implementing the efficient supply plans of life-SOC because the edge effect leads to an uncertain forecast of demand and supply plans. Thus, the conclusion calls for a consideration of the edge effect in order to improve efficiency and optimization in the allocation of public facilities.
