虽然行人有个人的偏好、目标和目的地，但行人群体的动态是可以预测的。行人只有在行人密度小的情况下才能自由移动。否则，他们的运动受到与其他行人的排斥相互作用的影响，从而产生自组织现象。由此产生的运动模式的例子是在相反移动的行人人群中统一行走方向的独立车道或在瓶颈处的通行方向振荡。如果行人在可变形的地面上留下脚印（例如，在公园等绿色空间），这还会引起有吸引力的相互作用，这种相互作用是通过环境的变化来调节的。在这种情况下，步行道系统将随着时间的推移而发展。相应的计算机模拟是开发优化行人设施和道路系统的宝贵工具。
Although pedestrians have individual preferences, aims, and destinations, the dynamics of pedestrian crowds is surprisingly predictable. Pedestrians can move freely only at small pedestrian densities. Otherwise their motion is affected by repulsive interactions with other pedestrians, giving rise to self-organization phenomena. Examples of the resulting patterns of motion are separate lanes of uniform walking direction in crowds of oppositely moving pedestrians or oscillations of the passing direction at bottlenecks. If pedestrians leave footprints on deformable ground (for example, in green spaces such as public parks) this additionally causes attractive interactions which are mediated by modifications of their environment. In such cases, systems of pedestrian trails will evolve over time. The corresponding computer simulations are a valuable tool for developing optimized pedestrian facilities and way systems.
