In this paper, advanced evacuation analysis simulation for passenger ship by using 3 degree-of-freedom dynamic model for human motion in 2 dimensional plane is performed. In order to describe passenger's behavior in complex evacuation situation, human is modeled as a rigid body which translates in...
