论文摘要
为了获得对交通流量的基本理解，得出了四个定理，以建立流量基本单元的运动学，即连续两辆车辆。第一个是确定车辆间距的两个临界距离，第二个是得出间隔范围和临界距离差异以及它们必须满足的关系，第三个是完成数学定义，并为时间稳定的时间稳定，并为保持距离的第四个范围提供了两次范围的范围，并确定了两个关键的范围。在此基础上，确定了交通流量现象和交通流量属性的组成，并简要阐明了交通流量的固有规律性。因此，获得了交通流量研究的基本理论框架。基于框架，简要审查了三个重要问题，即交通流量不稳定，阶段和经验数据集。
To gain essential understandings of traffic flow, four theorems are derived to establish the kinematics of the basic unit of traffic flow, namely two consecutive vehicles. The first is to determine the two critical distances of the vehicle spacing, the second is to derive the spacing margin and the critical distance difference as well as the relationship they must satisfy, the third is to complete the mathematical definition and give the necessary and sufficient condition for the time headway to remain constant, and the fourth is to derive the governing equation of the spacing margin and determine the two key constraint spaces of the motion of consecutive vehicles. On this basis, the composition of the traffic flow phenomenon and that of the traffic flow property are determined, and the inherent regularity of traffic flow is briefly elucidated. Thus, a basic theoretical framework specific to the study of traffic flow is obtained. Based on the framework, three important issues, namely traffic flow instability, phase, and empirical datasets, are briefly reviewed.
