列福尔托沃深隧道（莫斯科）的交通流状态：经验数据
States of Traffic Flow in Deep Lefortovo Tunnel (Moscow): Empirical Data
摘要：
本文提出了一个初步的交通流数据收集的列福尔托沃隧道位于莫斯科第三环形公路的分析。它示出，所观察到的隧道拥挤的交通实际上表现出合作的现象，在车辆运动，即，有一个区域的广泛分散状态的基本图，这是典型的同步交通的外观。此外，不同检测器测量的占用率、车辆速度和流量的空间自相关性也很重要。特别是在速度和占有率的相关性方面，它们的相关长度得到了大约1 km的值。研究了车辆系综动力学在占有率-速度平面上的相图。结果表明，该区域存在两个不同的区域：一个区域与合作车辆运动相匹配，包含一些核，动力学是纯混沌的;相平面的另一部分对应于堵塞形成的不可逆阶段。
英文摘要：
The paper presents a preliminary analysis of traffic flow data collected in the Lefortovo tunnel located on the 3-rd circular highway of Moscow. It is shown that the observed tunnel congested traffic in fact exhibits cooperative phenomena in vehicle motion, namely, there is a region of widely scatted states on the fundamental diagrams which is related typically to the appearance of synchronized traffic. Besides, the spatial autocorrelations in the occupancy, vehicle velocity, and flow rate measured by different detectors are found to be essential. Especially it concerns the correlations in the velocity and occupancy, their correlation length gets values about 1 km. The phase portrait of the vehicle ensemble dynamics on the occupancy-velocity plane is also studied. It is demonstrated that there are two substantially different region on it. One matches actually the cooperative vehicle motion and contains some kernel where the dynamics is pure chaotic. The other part of the phase plane corresponds to the irreversible stage of jam formation.
