Today, many Japanese architects and engineers use graphic-analytical method, provided by Building Center of Japan to evaluate their plans for safety escaping. There was also another graphic-analytical method which was established by Predtechenskii and Milinskii in USSR by 1969. However, these methods do not reflect enough characteristics in human traffic flow. The purpose of this study is to clarify the problems of these conventional methods, and to propose a new method. This is Part I of a series of study, reporting following contents ; (1) Discovery of large deferences when the two methods were applied in a same situation. (2) Pointing out as follows ; a. Cause for the deferences came from not considering the deference of speeds between top and bottom of the traffic mass. b. Necessity for a model which can reflect spread of human mass in process, based on correlationship between density and velocity of a human traffic flow. (3) Explanation of Elastic Block Model logic. (4) Application of E. B Model to the same situation.
