Quantification of spatiotemporal phenomena by means of cellular automata techniques

Hütt, M.-Th.; Neff, R. - In: Physica A: Statistical Mechanics and its Applications 289 (2001) 3, pp. 498-516

inspired by cellular automata as well as by more complex spatiotemporal dynamics. In particular, spatial and temporal … structures, which can be found in aggregation and clustering phenomena, are quantified by introducing the concept of cellular … automata (CA) measures for homogeneity and for the amount of fluctuations contributing to the observed dynamics. The aim of …

Simulation of pedestrian dynamics using a two-dimensional cellular automaton

Burstedde, C; Klauck, K; Schadschneider, A; Zittartz, J - In: Physica A: Statistical Mechanics and its Applications 295 (2001) 3, pp. 507-525

We propose a two-dimensional cellular automaton model to simulate pedestrian traffic. It is a vmax=1 model with exclusion statistics and parallel dynamics. Long-range interactions between the pedestrians are mediated by a so-called floor field which modifies the transition rates to neighbouring...

A microscopic model for packet transport in the Internet

Huisinga, Torsten; Barlovic, Robert; Knospe, Wolfgang; … - In: Physica A: Statistical Mechanics and its Applications 294 (2001) 1, pp. 249-256

A microscopic description of packet transport in the Internet by using a simple cellular automaton model is presented. A generalised exclusion process is introduced which allows to study travel times of the particles (‘data packets’) along a fixed path in the network. Computer simulations...

The test of the finite-size scaling relations for the six-dimensional Ising model on the Creutz cellular automaton

Aktekin, N; Erkoç, Ş - In: Physica A: Statistical Mechanics and its Applications 284 (2000) 1, pp. 206-214

The six-dimensional Ising model is simulated on the Creutz cellular automaton using the finite-size lattices with the linear dimension 4⩽L⩽10. The exponents in the finite-size scaling relations for the magnetic susceptibility and the order parameter at the infinite-lattice critical...

Statistical physics of traffic flow

Schadschneider, Andreas - In: Physica A: Statistical Mechanics and its Applications 285 (2000) 1, pp. 101-120

cellular automata models have allowed for large-scale simulations of large traffic networks faster than real time. On the other … current status of cellular automata models for traffic flow is reviewed with special emphasis on nonequilibrium effects (e …

Walks in rigid environments

Bunimovich, Leonid A. - In: Physica A: Statistical Mechanics and its Applications 279 (2000) 1, pp. 169-179

We consider a motion of the particle in a random configuration of scatterers on a lattice. There is a feedback of the particle on an environment which is characterized by its rigidity r. The type of a scatterer at a site of the lattice changes after the rth visit of the particle to this site. We...

Periodic solutions of a non-linear traffic model

Safonov, L.A.; Tomer, E.; Strygin, V.V.; Havlin, S. - In: Physica A: Statistical Mechanics and its Applications 285 (2000) 1, pp. 147-155

A car-following model of single-lane traffic is studied. Traffic flow is modeled by a system of Newton-type ordinary differential equations. Different solutions (equilibria and limit cycles) of this system correspond to different phases of traffic. Limit cycles appear as results of Hopf...
