As the first step of the strategy establishment for site planning of out-door refuge places from wide-spreading earthquake fires, the formulation of an algorithm searching for optimal disposition is proposed by an application of Linear Programming Method (Transportation Problem).
In urban areas in Japan, because of consisting of overcrowded wooden houses, open spaces as for refuge from fires caused by a large earthquake are indispensably important to be considered. In many cities these refuge places have been already assigned, but in most cases, their sizes and locations are, since its assignment is too easy, unappropriate.
In this paper an examination of their appropriateness as refuge places is introduced from the standpoint of citizen's safety, under the condition that the refugee's total travelling distance should be minimized, through which a better and optimal solution was actually obtained in an exemplified city.
