TLDR
A stochastic discrete automaton model is introduced to simulate freeway traffic and shows a transition from laminar traffic flow to start-stop- waves with increasing vehicle density, as is observed in real freeway traffic.Abstract:
We introduce a stochastic discrete automaton model to simulate freeway traffic. Monte-Carlo simulations of the model show a transition from laminar traffic flow to start-stop- waves with increasing vehicle density, as is observed in real freeway traffic. For special cases analytical results can be obtained.read more

Traveling-wave solutions of the diffusively corrected kinematic-wave model
TL;DR: In this paper, diffusively corrected kinematic wave model (DCKWM) is explored in regard to its ability to reproduce data that are inconsistent with the classical KWM, and travel-wave solutions of the DCKWM are shown to reproduce flows corresponding to the interior of shock waves and to the edges of acceleration waves.

Stochastic Description of Traffic Flow
TL;DR: The model is shown to correctly predict both qualitative as well as quantitative traffic observables for any highway geometry and captures interesting multi-scale phenomena in traffic flows after a simulated accident which lead to oscillatory, dissipating, traffic waves with different periods per lane.

Graph Cellular Automata with Relation-Based Neighbourhoods of Cells for Complex Systems Modelling: A Case of Traffic Simulation
TL;DR: This article proposes a graph cellular automaton with a variable configuration of cells and relation-based neighbourhoods (r–GCA), which enables modelling of phenomena found in complex systems taking into account the interaction between the existing objects.

Horst W. Hamacher,Horst W. Hamacher,S. Heller,S. Heller,W. Klein,W. Klein,Gerta Köster,Gerta Köster,Stefan Ruzika,Stefan Ruzika +9 more
TL;DR: A novel modeling approach – the sandwich approach – to deal with evacuation time bounds (ETB) - in which lower and upper bounds for the evacuation time are calculated, and practical experiences with the Betzenberg, the region containing the Fritz-Walter soccer stadium in Kaiserslautern, Germany are reported.
