"Integrated Model of Emergency Evacuation of People after a Big Earthquake at the Busy Quarter near a Major Junction Station in Suburban Tokyo"
In Tokyo we may have a big earthquake even today. We have national and local plans to prevent the catastrophe caused by a big earthquake in Japan. In the metropolitan regions huge numbers of people commute by train between their homes and the CBD area of the major city everyday. Accordingly, there are some busy shopping streets and big stores near to the major junction station in the suburbs. However, we have only few plans to evacuate a number of people who are unfamiliar with the places on the way between their homes and places of work. In this study, we present the framework of an integrated model of emergency evacuation of people after a big earthquake at the busy quarter near a major junction station in suburban Tokyo, Japan. In addition, we explain the ideas of a macro evacuation model described by System Dynamics and some micro evacuation models using one of the multi agent based systems. By these models we can simulate evacuation process from the big store, from the train through a platform of a railway station, from an underground floor through stairs and escalators and from buildings to some safer places through the streets on which many obstacles are scattered.
