Microscopic modeling of traffic flow: investigation of collision free vehicle dynamics.

Abstract: The continuous growth of road traffic volumes leads to significant environmental and economical problems. For more than four decades efforts have been done to understand the dynamics of traffic flow in order to find out how to optimize traffic with respect to a reduction of environmental impacts and economical loss due to congestion. A microsopic model of traffic flow is proposed, adding to the understanding of the different types of congestion found in traffic flow.

Experimental properties of complexity in traffic flow

Abstract: Experimental investigations of a complexity in traffic flow are presented. It is shown that this complexity is linked to space-time transitions between three qualitative different kinds of traffic: "free" traffic flow, "synchronized" traffic flow, and traffic jams. Peculiarities of "synchronized" traffic flow and jams that are responsible for a complex behavior of traffic are found.

Observations on the dynamics of a congestion control algorithm: the effects of two-way traffic

Abstract: We use simulation to study the dynamics of the congestion cent rol algorithm embedded in the BSD 4.3-Tahoe TCP implementation. We investigate the simple case of a few TCP connections, originating and terminating at the same pair of hosts, using a single bottleneck link. This work is an extension of our earlier work ([16]), where one-way traffic (i.e., all of the sources are on the same host and all of the destinations are on the other host) was studied. In this paper we investigate the dynamics that results from two-way traffic (in which there are data sources on both hosts). We find that the one-way traffic clustering and loss-synchronization phenomena d~cussed in [16] persist in this new situation, albeit in a slightly modified form. In addition, there are two new phenomena not present in the earlier study: (1) ACK-compression, which is due to the interaction of data and ACK packets and gives rise to rapid fluctuations in queue length, and (2) an out-of-phase queue-synchronization mode, which keeps link utilization less than optimal even in the limit of very large buffers. These phenomena are helpful in understanding results from an earlier study of network oscillations ([19]).

Experimental features and characteristics of traffic jams

Abstract: Based on experimental investigations of traffic on highways it is shown that traffic jams can move stable through a highway keeping their structure and characteristic parameters for a long time (at least for about 50 min, when the jams moved through the longest, 13.1 km, section of the investigated highways). The experimental features of an almost stationary moving jam have been found. An occurrence of complex space-time structures of traffic inside a wide traffic jam has been observed. \textcopyright{} 1996 The American Physical Society.
