The purpose of this paper is to make a planning, which decides the place of shelter for the urban dwellers when there happened a great earthquake. That is, the aim of the planning is to appoint an appropriate route and place for the refugee so that they can escape from the spread of fire as soon as possible. We assigned large open spaces for shelters and tried to find out the optimum distribution of inhabitants to these places without exceeding the number of person admitted to the place. We used computers to develop a simulation model, which is composed of following three parts. (1) EES (Emergency Escaping Simulation model) This is a person flow simulation model and the escape on the networked-city is simulated. Each state of escape, in the process of time, can be traced. (2) DSD (Destination Searching Dynamic model) The destination space of each residential zone is decided to have the minimum move (person number×moved distance) under the condition of space capacity. (3) Optimum Planning model Above two models are combined at this stage, and besides the distance, the time lag due to the traffic congestion is taken into consideration to get the optimum solution. The convergent solution as the best planning, has the minimum time and move satisfying the required conditions. We also used graphic display (C.R.T.) to observe the process of simulation visually, and the result is stored in 16mm films.
