Optimization research of building exports positions based on the evacuating movement

To master group rules pedestrian movement emerged is prior to construct and plan the base of pedestrians design Tightness. The existing research focuses on the research of pedestrian movement rules, especially for behavior in evacuation. But there is just lack of engineering practical calculation method with respect to infrastructure layout optimization according to the pedestrian movement characteristics. This paper puts forward a method based on the cellular automata method to simulate group behavior in the cases of evacuation. On this basis, this paper gives the optimization method of the building export position. Meanwhile, the method in the paper also considering the construction cost, showing a strong practicability.
