Simulation of evacuation based on continuous geometry model

A new continuous geometry evacuation model was developed based on analyzing and comparing existing models. The model considering exit attraction was used to deal with the problem of exit selection in a multiple exits plan. The way finding algorithm was introduced to circumambulate the obstacle in the plan. The behaviors during evacuation such as overtaking, waiting, rounding were well presented in the simulation with the geometric algorithm. The result of the simulation shows the superiority and validity of this model.
