论文摘要
如何在模拟中重现现实运动一直是行人动态的一个基本问题，而对于当前研究的关键挑战是运动选择和人类行为的自然相关性。为了推进研究，我们根据Voronoi图和Delaunay图来解构行人人群的二维空间，因此，考虑长期路线选择和实时速度选择，并因此制定了行为模型。模拟结果与现实世界动作之间的比较表明，行为模型不仅可以处理传统的场景，而且还可以在挑战性冲突的情况下描述良好的运动。空间解构思想提供了一种几何观点，可以识别和复制行人行为，它可以进一步受益于对行人动态甚至机器人导航的理解和实现。
How to reproduce realistic motion in simulations has always been a fundamental problem for pedestrian dynamics, and a critical challenge for current studies is the natural correlation of the movement choices and the human behaviours. To advance the study, we deconstruct the two-dimensional space of pedestrian crowds with a behavioural motion network on basis of Voronoi diagram and Delaunay diagram, and accordingly formulate a behavioural model considering both the long-term route choice and the real-time velocity choice. The comparisons between simulation results and real-world movements suggest that the behavioural model can not only deal with traditional scenarios but also be capable of describing well-agreed movements in challenging conflicting situations. The spatial deconstruction idea provides a geometric perspective to recognize and reproduce the pedestrian behaviours, and it can further benefit the understanding and realization of pedestrian dynamics and even robot navigation.
