Influences of the driver’s bounded rationality on micro driving behavior, fuel consumption and emissions
TLDR
In this paper, an extended car-following model was proposed to study the influence of the driver's bounded rationality on micro driving behavior and fuel consumption, CO, HC and NOX of each vehicle under two typical cases.Abstract:
In this paper, we propose an extended car-following model to study the influences of the driver’s bounded rationality on his/her micro driving behavior, and the fuel consumption, CO, HC and NOX of each vehicle under two typical cases, where Case I is the starting process and Case II is the evolution process of a small perturbation. The numerical results indicate that considering the driver’s bounded rationality will reduce his/her speed during the starting process and improve the stability of the traffic flow during the evolution of the small perturbation, and reduce the total fuel consumption, CO, HC and NOX of each vehicle under the above two cases.read more

Analysis of mixed traffic flow with human-driving and autonomous cars based on car-following model
TL;DR: A new mathematical model with adjustable sensitivity and smooth factor was proposed to describe the autonomous car’s moving behavior in which smooth factor is used to balance the front and back headway in a flow to support the stability criteria in traffic flow.

An extended continuum model accounting for the driver's timid and aggressive attributions
TL;DR: Considering the driver's timid and aggressive behaviors simultaneously, a new continuum model is put forward in this paper, which shows that aggressive driving is better than timid act because the aggressive driver will adjust his speed timely according to the leading car's speed.

An extended macro traffic flow model accounting for the driver’s bounded rationality and numerical tests
TL;DR: In this article, a macro traffic flow model was proposed to explore the effects of the driver's bounded rationality on the evolutions of traffic waves (which include shock and rarefaction waves) and small perturbation, and on the fuel consumption and emissions during the evolution process.

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.

A behavioural car-following model for computer simulation
TL;DR: A new model is constructed for the response of the following vehicle based on the assumption that each driver sets limits to his desired braking and acceleration rates and it is shown that when realistic values are assigned to the parameters in a simulation, the model reproduces the characteristics of real traffic flow.

Full velocity difference model for a car-following theory.
TL;DR: This paper presents a full velocity difference model for a car-following theory based on the previous models in the literature, and finds that the model can describe the phase transition of traffic flow and estimate the evolution of traffic congestion.

TL;DR: Floating car data of car-following behavior in cities were compared to existing microsimulation models, after their parameters had been calibrated to the experimental data and good results were obtained with the proposed generalized force model.
