行人动力学表现出各种迷人而令人惊讶的集体现象（车道形成，门口的流量振荡等）。提出了一种能够再现这些效应的二维元胞自动机模型。受趋化原理的启发，行人之间的相互作用由所谓的地板场来调节。这个磁场的作用类似于蚂蚁为指引其他个体找到食物而产生的化学痕迹。由于其简单性，该模型允许比实时更快地模拟大量人群。
Pedestrian dynamics exhibits a variety of fascinating and surprising collective phenomena (lane formation, flow oscillations at doors etc.). A 2-dimensional cellular automaton model is presented which is able to reproduce these effects. Inspired by the principles of chemotaxis the interactions between the pedestrians are mediated by a so-called floor field. This field has a similar effect as the chemical trace created e.g. by ants to guide other individuals to food places. Due to its simplicity the model allows for faster than real time simulations of large crowds.
