人群的数值模拟是一项具有挑战性的任务，已经建立了许多微观层次上的行人动力学模型。这些模型的一个目的是再现复杂环境中人群的真实、特别是无碰撞的运动。这项工作研究了三种方法，他们的能力，重现在复杂的动态环境中的行人人群的无碰撞运动。基线模型是众所周知的社会力量模型。在社会力模型中，行人不会明确地避免彼此，而第二个模型扩展了社会力模型，以明确地避免碰撞。第三种模型产生的避碰行为是通过计算速度障碍来实现的。这些是速度空间中的障碍物，这意味着如果行人选择了位于速度障碍物内的速度，那么在某个时候会发生碰撞。这项工作讨论了模型及其集成在一个多智能体仿真框架。该模型进行了测试，从现实世界的实验数据在工业大学柏林。在这个实验中，两个行人流以90度角相交。在这项工作中，模型的性能方面的再现一个现实的人群运动和他们的计算复杂性进行了讨论。
Numerical simulation of human crowds is a challenging task and a number of models to simulate pedestrian dynamics on a microscopic level have been established. One aim of those models is to reproduce a realistic, and in particular collision-free, movement of crowds in complex environments. This work investigates three approaches on their capability to reproduce a collision-free movement of pedestrian crowds in complex dynamic environments. The baseline model is the well-known social force model. While in the social force model pedestrians do not explicitly avoid each other, the second model extends the social force model to avoid collisions explicitly. The observed collision-avoiding behavior produced by the third model is reached by calculating velocity obstacles. These are obstacles in the velocity space, meaning that if a pedestrian chooses a velocity that lies inside the velocity obstacle, then a collision occur at some time. This work discusses the models and their integration in a multi-agent simulation framework. The models are tested on data from a real-world experiment conducted at Technische Universitat Berlin. In this experiment, two pedestrian flows intersected at an angle of 90∘. The models’ performance with regard to the reproduction of a realistic crowds movement and their computational complexity are discussed in this work.
