Cluster formation and anomalous fundamental diagram in an ant trail model
Katsuhiro Nishinari, Debashish Chowdhury, Andreas Schadschneider
A recently proposed stochastic cellular automaton model ({\it J. Phys. A 35, L573 (2002)}), motivated by the motions of ants in a trail, is investigated in detail in this paper. Th…
Matrix product approach for the asymmetric random average process
Frank Zielen, Andreas Schadschneider
We consider the asymmetric random average process which is a one-dimensional stochastic lattice model with nearest neighbour interaction but continuous and unbounded state variable…
Stochastic Light-Cone CTMRG: a new DMRG approach to stochastic models
A. Kemper, A. Gendiar, T. Nishino +2
We develop a new variant of the recently introduced stochastic transfer-matrix DMRG which we call stochastic light-cone corner-transfer-matrix DMRG (LCTMRG). It is a numerical meth…
Boundary-induced phase transitions in a space-continuous traffic model with non-unique flow-density relation
Alireza Namazi, Nils Eissfeldt, Peter Wagner +1
The Krauss-model is a stochastic model for traffic flow which is continuous in space. For periodic boundary conditions it is well understood and known to display a non-unique flow-…
Friction effects and clogging in a cellular automaton model for pedestrian dynamics
Ansgar Kirchner, Katsuhiro Nishinari, Andreas Schadschneider
We investigate the role of conflicts in pedestrian traffic, i.e. situations where two or more people try to enter the same space. Therefore a recently introduced cellular automaton…
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…
Simulation of evacuation processes using a bionics-inspired cellular automaton model for pedestrian dynamics
Ansgar Kirchner, Andreas Schadschneider
We present simulations of evacuation processes using a recently introduced cellular automaton model for pedestrian dynamics. This model applies a bionics approach to describe the i…
Single-vehicle data of highway traffic: microscopic description of traffic phases
Wolfgang Knospe, Ludger Santen, Andreas Schadschneider +1
We present a detailed analysis of single-vehicle data which sheds some light on the microscopic interaction of the vehicles. Besides the analysis of free flow and synchronized traf…
A realistic two-lane traffic model for highway traffic
W. Knospe, L. Santen, A. Schadschneider +1
A two-lane extension of a recently proposed cellular automaton model for traffic flow is discussed. The analysis focuses on the reproduction of the lane usage inversion and the den…
Comment on `Garden of Eden states in traffic model revisited'
Andreas Schadschneider, Michael Schreckenberg
Recently, Huang and Lin suggested a combination of two successfull mean-field theories, the 2-cluster approximation and paradisical mean-field, for the Nagel-Schreckenberg cellular…
A cellular-automata model of flow in ant-trails: non-monotonic variation of speed with density
Debashish Chowdhury, Vishwesha Guttal, Katsuhiro Nishinari +1
Generically, in models of driven interacting particles the average speed of the particles decreases monotonically with increasing density. We propose a counter-example, motivated b…
