拥挤状态下行人动力学的相位共存
Phase coexistence in congested states of pedestrian dynamics
摘要：
拥挤的行人交通的实验结果。对于数据分析，我们应用了一种方法，该方法提供了单个尺度上的测量值。由此产生的速度-密度关系显示了移动和停止状态的共存，揭示了行人基本图的复杂结构，并支持对行人步行特征的新见解。此外，我们引入了一个类似于事件驱动的方法模型。再现了速度-密度关系以及相分离。参数分布的变化表明，行人的多样性是至关重要的相位分离。
英文摘要：
Experimental results for congested pedestrian traffic are presented. For data analysis we apply a method providing measurements on an individual scale. The resulting velocity-density relation shows a coexistence of moving and stopping states revealing the complex structure of pedestrian fundamental diagrams and supporting new insights into the characteristics of pedestrian congestions. Furthermore we introduce a model similar to event driven approaches. The velocity-density relation as well as the phase separation is reproduced. Variation of the parameter distribution indicates that the diversity of pedestrians is crucial for phase separation.
