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…
Liquid, Glass and Crystal in Two-dimensional Hard disks
Ludger Santen, Werner Krauth
We study the thermodynamic and dynamic phase transitions in two-dimensional polydisperse hard disks using Monte Carlo methods. A conventional local Monte Carlo algorithm allows us…
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…
A new cellular automata model for city traffic
A. Schadschneider, D. Chowdhury, E. Brockfeld +3
We present a new cellular automata model of vehicular traffic in cities by combining ideas borrowed from the Biham-Middleton-Levine (BML) model of city traffic and the Nagel-Schrec…
Vehicular Traffic: A System of Interacting Particles Driven Far From Equilibrium
Debashish Chowdhury, Ludger Santen, Andreas Schadschneider
In recent years statistical physicists have developed {\it discrete} "particle-hopping" models of vehicular traffic, usually formulated in terms of {\it cellular automata}, which a…
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…
