行人移动的密度和速度之间的经验关系尚未得到完全分析，特别是关于在中高密度下决定这种关系的“微观”原因。研究这种相关性的最简单系统是行人沿直线的正常移动（单列移动）。本文介绍了在实验室条件下该系统的实验结果，并讨论了以下观察结果：数据显示速度和密度的倒数之间呈线性关系，密度的倒数可视为一名行人移动所需的长度。此外，我们将单列移动的结果与平面移动的文献数据进行了比较。这种比较表明基本图表之间存在意想不到的一致性，这表明在密度范围1 m⁻² > ρ > 5 m⁻²内，横向干扰对速度 - 密度关系的影响可忽略不计。此外，我们测试了一种自动记录行人流量特征的方法。我们给出了该方法测量范围和精度的初步结果。
The empirical relation between density and velocity of pedestrian movement has not been completely analysed, particularly with regard to the 'microscopic' causes which determine the relation at medium and high densities. The simplest system for the investigation of this dependence is the normal movement of pedestrians along a line (single-file movement). This paper presents experimental results for this system under laboratory conditions and discusses the following observations: the data show a linear relation between the velocity and the inverse of the density, which can be regarded as the required length for one pedestrian to move. Furthermore, we compare the results for the single-file movement with literature data for the movement in a plane. This comparison shows an unexpected conformance between the fundamental diagrams, indicating that lateral interference has negligible influence on the velocity - density relation in the density domain 1 m(-2) >rho > 5 m(-2). In addition, we test a procedure for automatic recording of pedestrian flow characteristics. We present preliminary results on the measurement range and accuracy of this method.
