TLDR
It is shown that the single-lane dynamics can be extended to the two-lane case without changing the basic properties of the model, which are known to be in good agreement with empirical single-vehicle data.Abstract:
A two-lane extension of a recently proposed cellular automaton model for traffic flow is discussed. The analysis focuses on the reproduction of the lane usage inversion and the density dependence of the number of lane changes. It is shown that the single-lane dynamics can be extended to the two-lane case without changing the basic properties of the model, which are known to be in good agreement with empirical single-vehicle data. Therefore it is possible to reproduce various empirically observed two-lane phenomena, like the synchronization of the lanes, without fine tuning of the model parameters.read more

A realistic two-lane cellular automata traffic model considering aggressive lane-changing behavior of fast vehicle
TL;DR: A new symmetric two-lane cellular automata model is proposed and it is shown that aggressive lane-changing behavior of fast vehicle can depress the plug formed by slow vehicles and improve traffic flow in mixed traffic in the intermediate density range.

Honk Effect in the Two-Lane Cellular Automaton Model for Traffic Flow
TL;DR: It is shown that the honk has almost no effect in the homogeneous traffic whereas it enhances the flux in the intermediate density regime for the heterogeneous traffic and it is argued that the Honk behavior is not encouraged in the asymmetric two-lane model.

Cellular automaton model for mixed traffic flow with motorcycles
Jianping Meng,Jianping Meng,Jianping Meng,S. Q. Dai,Li-Yun Dong,Jie-Fang Zhang,Jie-Fang Zhang +6 more
TL;DR: In this paper, a single-lane cellular automaton model is proposed to simulate mixed traffic with motorcycles, where the maximum total flow increases first and then decreases with increasing motorcycle density and the transition of the total flow from the free flow to congested flow is smooth.

Kai Nagel,Michael Schreckenberg +1 more
TL;DR: 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.

Statistical physics of vehicular traffic and some related systems
TL;DR: In this paper, a critical review of particle-hopping models of vehicular traffic is presented, focusing on the results obtained mainly from the so-called "particle hopping" models, particularly emphasizing those formulated in recent years using the language of cellular automata.

Metastable states in cellular automata for traffic flow
TL;DR: It is shown that this model exhibits metastable states, thus sheding some light on the prerequisites for the occurance of hysteresis effects in the flow-density relation, and proposes a simple generalization of the NaSch model by introducing a velocity-dependent randomization.
