摘要:

我们目前的实验结果获得的一维流动,使用高精度的运动捕捉。获得完整的行人轨迹。在本文中,我们专注于基本图,以及瞬时速度和空间车头时距(到前车的距离)之间的关系。虽然后者被发现是线性的,在以前的实验中,我们表明,这是一个分段的线性行为,发现如果更大的密度范围被覆盖。事实上,我们的数据清楚地展示了三个不同的制度,在行人的行为,遵循对方。这些制度之间的过渡发生在约1.1和3米的空间车头时距,分别。这一发现可能对未来的建模有用。

英文摘要:

We present experimental results obtained for a one-dimensional flow using high precision motion capture. The full pedestrians' trajectories are obtained. In this paper, we focus on the fundamental diagram, and on the relation between the instantaneous velocity and spatial headway (distance to the predecessor). While the latter was found to be linear in previous experiments, we show that it is rather a piecewise linear behavior which is found if larger density ranges are covered. Indeed, our data clearly exhibits three distinct regimes in the behavior of pedestrians that follow each other. The transitions between these regimes occur at spatial headways of about 1.1 and 3 m, respectively. This finding could be useful for future modeling.
