Abstract
In the present paper a review and numerical comparison of a special class of multi-phase traffic theories based on microscopic, kinetic and macroscopic traffic models is given. Macroscopic traffic equations with multi-valued fundamental diagrams are derived from different microscopic and kinetic models. Numerical experiments show similarities and differences of the models, in particular, for the appearance and structure of stop and go waves for highway traffic in dense situations. For all models, but one, phase transitions can appear near bottlenecks depending on the local density and velocity of the flow.

Criticism of generally accepted fundamentals and methodologies of traffic and transportation theory: A brief review

TL;DR: The three-phase traffic theory is discussed as the basis for traffic flow modeling as well as the network breakdown minimization (BM) principle for the optimization of traffic and transportation networks with road bottlenecks.

Failure of classical traffic flow theories: Stochastic highway capacity and automatic driving

TL;DR: A deep connection is shown between the understanding of empirical stochastic highway capacity and a reliable analysis of automatic driving vehicles in traffic flow and the increase in the probability of traffic breakdown throughautomatic driving vehicles can be realized, even if any platoon of automaticdriving vehicles satisfies condition for string stability.

Comparative model accuracy of a data-fitted generalized Aw-Rascle-Zhang model

TL;DR: An approach to determine the parameter functions of the GARZ model from fundamental diagram measurement data is presented and the predictive accuracy of the resulting data-fitted GARz model is compared to other traffic models by means of a three-detector test setup.

Effect of driver over-acceleration on traffic breakdown in three-phase cellular automaton traffic flow models

TL;DR: A new three-phase CA traffic flow model explains the set of the fundamental empirical features of traffic breakdown in real heterogeneous traffic flow consisting of passenger vehicles and trucks and simulates also quantitative traffic pattern characteristics as measured inreal heterogeneous flow.

Macroscopic traffic flow modeling with adaptive cruise control

TL;DR: CACC vehicles increase the stabilization of traffic flow, with respect to both small and large perturbations, compared to ACC ones, and the proposed CACC approach can better improve the dynamic equilibrium capacity and traffic dynamics, especially at the on-ramp bottleneck.

Congested traffic states in empirical observations and microscopic simulations

TL;DR: It is shown that the results of the microscopic model can be understood by formulating the theoretical phase diagram for bottlenecks in a more general way, and a local drop of the road capacity induced by parameter variations has essentially the same effect as an on-ramp.

Dynamical model of traffic congestion and numerical simulation

TL;DR: In this model, the legal velocity function is introduced, which is a function of the headway of the preceding vehicle, and the evolution of traffic congestion is observed with the development of time.
