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

Agent-based traffic simulation and traffic signal timing optimization with GPU
Zhen Shen,Kai Wang,Fenghua Zhu +2 more
TL;DR: This paper builds an MAS model for a road network of four signalized intersections and uses a Genetic Algorithm (GA) to optimize the traffic signal timing with the objective of maximizing the number of the vehicles leaving the network in a given period of time.

Jamming transition of high-dimensional traffic dynamics
TL;DR: In this paper, the phase transition and critical phenomenon in high-dimensional traffic flow were investigated numerically and analytically, and the phase separation line, spinodal line, and critical point were calculated from the Ginzburg-Landau (TDGL) equation.

Exact solution of an exclusion process with three classes of particles and vacancies
TL;DR: In this article, the authors present an exact solution for an asymmetric exclusion process on a ring with three classes of particles and vacancies using a matrix-product Ansatz, and find exact expressions for the weights of the configurations in the stationary state.

A stochastic cellular automaton model for traffic flow with multiple metastable states
TL;DR: A new stochastic cellular automaton model of traffic flow, which includes slow-to-start effects and a driver's perspective, is proposed by extending the Burgers CA and the Nagel–Schreckenberg CA model.

The green wave model of two-dimensional traffic: Transitions in the flow properties and in the geometry of the traffic jam
János Török,János Kertész +1 more
TL;DR: The green wave model (GWM), the parallel updating version of the two-dimensional traffic model of Biham et al, is studied to extrapolate to the infinite system size which indicates a nonzero density transition from the free flow to the congested state (jamming transition).
