摘要
通过改进传统社会力模型的受力作用、修改建模维度和运动视角、修正模型的主要参数,使之适用于三维空间楼梯疏散的仿真建模。通过与实际场景下行人楼梯疏散特征的比较,验证了改进后的模拟结果在行人下楼的平均速度、人流量、疏散时间等方面的准确性。说明该模型如何模拟人群下楼过程中的典型现象。
An improved social force model is presented through modifying the forces,simulation dimension,motion perspective and main parameters of the traditional social force model,to simulate the three-dimensional stairway evacuation.Through comparing to the real scene,it was verified that the improved model can simulate more accurately in the average velocity,the person flow and the evacuation time of pedestrian in stairway.The simulation of typical phenomenon appearing in the process of pedestrian in stairway was illustrated.
