Abstract
The empirical data on traffic flows collected in the linear portion of the Lefortovsky tunnel of the third Moscow transport ring were analyzed. It was shown that the crowded traffic observed in the tunnel is indeed characterized by the synchronized vehicular traffic. In particular, long-range spatial correlations in their motion velocities and the region of “widely scattered states”, i.e., two typical properties of the synchronized vehicular traffic phase, were detected in the fundamental diagram. Moreover, the phase diagram of the traffic flow dynamics showed two regions with essentially different properties, which are separated by a narrow layer with a virtually fixed vehicle density. One of them corresponds to synchronized vehicular traffic and contains a core of chaotic dynamics. Another region corresponds to irreversible formation of wide moving jams.
