Optimization potential of a real highway network: an empirical study
Wolfgang Knospe, Ludger Santen, Andreas Schadschneider +1
Empirical observations and theoretical studies indicate that the overall travel-time of vehicles in a traffic network can be optimized by means of ramp metering control systems. He…
CA Models for Traffic Flow: Comparison with Empirical Single-Vehicle Data
W. Knospe, L. Santen, A. Schadschneider +1
Although traffic simulations with cellular-automata models give meaningful results compared with empirical data, highway traffic requires a more detailed description of the element…
Statistical Analysis of Freeway Traffic
L. Neubert, L. Santen, A. Schadschneider +1
Single-vehicle data of freeway traffic as well as selected Floating-Car (FC) data are analyzed in great detail. Traffic states are distinguished by means of aggregated data. We pro…
Density fluctuations and phase separation in a traffic flow model
S. Lubeck, M. Schreckenberg, K. D. Usadel
Within the Nagel-Schreckenberg traffic flow model we consider the transition from the free flow regime to the jammed regime. We introduce a method of analyzing the data which is ba…
Garden of Eden states in traffic models
Andreas Schadschneider, Michael Schreckenberg
We investigate the allowed configurations in the stationary state of the cellular automaton model for single-lane traffic. It is found that certain states in the configuration spac…
Disorder Effects in CA-Models for Traffic Flow
W. Knospe, L. Santen, A. Schadschneider +1
We investigate the effect of quenched disorder in the Nagel-Schreckenberg model of traffic flow. Spatial inhomogenities, i.e. lattice sites where the braking probability is enlarge…
