Abstract
Natural open-spaces are important for residents to enjoy in daily life and to take refuge in case of earthquake disaster. Therefore, value of space must be evaluated considering with mitigation function. Especially, mitigation value of natural open-space is evaluated focused on evacuation action and safety for radiant heat.
Firstly, this paper shows that a simulation of evacuation action is done considering with divided region and adjacency relation ofchou-chou-moku. This simulation analysis is done using dual graph. And the assumption evacuating number of person every space is calculated. Mitigation value is evaluated using number of person and safety every space.
Secondly, this value is evaluated focused on temporal evacuation life.
