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

Self-organized criticality in 1D traffic flow model with inflow or outflow
TL;DR: In this paper, the authors extended the asymmetric simple-exclusion model with parallel dynamics to take into account the exchange of cars between different lanes on a multi-lane roadway and showed that the jam-interval distribution satisfies the finite-size scaling form ns(L) approximately=L- beta f(s/Lv) with beta = 2v.

Proposed CAEva Simulation Method for Evacuation of People from a Buildings on Fire
TL;DR: This paper presents practical applications of the cellular automata theory for building fire simulation using the CAEva method and proposes solutions so that it shall be easier to envisage consequences of problematic decisions causing temporary or permanent unavailability of escape routes.

Dangerous situations within the framework of the Nagel–Schreckenberg model
TL;DR: In this article, the authors investigated the occurrence of dangerous situations (DS) within the framework of the Nagel-Schreckenberg model and showed that when vmax = 1, there will be no DS in both deterministic and non-deterministic cases.

A forward-looking anticipative viscous high-order continuum model considering two leading vehicles for traffic flow through wireless V2X communication in autonomous and connected vehicle environment
TL;DR: This work proposes a new car-following model which integrates space and velocity changes of two leading vehicles implemented through V2X wireless communication in autonomous and connected vehicles environment and derives a corresponding macroscopic viscous continuum traffic flow model, more realistic and meaningful than those coming from an analogy of Navier–Stokes equations.
