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.

Cellular automaton model simulating traffic flow at an uncontrolled t-shaped intersection

TL;DR: The authors' simulation results suggest that priority should be given to either through cars or to turning cars according to the ratio of the turning cars in order to obtain the optimization of the system.

Investigating road safety issues through a microsimulation model

TL;DR: A calibrated microsimulation model has been developed to analyze vehicle trajectories, and hence vehicle interactions, in some different scenarios and verify traffic safety levels and results indicate that the methodology can be useful in the estimation of safety performance indicators and in evaluating traffic control measures.

A Survey of Cellular Automata: Types, Dynamics, Non-uniformity and Applications

TL;DR: In this article, a survey of cellular automata is presented, focusing on non-uniformity in CAs and especially on elementary CAs, which have been very useful in solving several real-life problems.

Analysis of honk effect on the traffic flow in a cellular automaton model

TL;DR: The paper mainly studies the following vehicle’s honk effect on the driver of its predecessors in the single-lane cellular automaton model (CA model) and concludes that the performance of the new CA model proposed in the paper is the best and more consistent with the real traffic.

Study of Freeway Speed Limit Control Based on Three-Phase Traffic Theory:

TL;DR: It is found that speed limit control can suppress moving jam emergence, which occurs without speed limitation, and these effects are associated with the probabilistic character of traffic breakdown at a bottleneck as well as with complex spatiotemporal congested pattern features.
