In this paper, we investigate the CO2 emission in a traffic flow mixed with multi-class vehicles by use of an improved optimal velocity model with different vehicles. We explore numerically the dependence of the total CO2 emission rate and the additional CO2 emission on the variation of the...

In this paper, traffic states and jamming transitions on two-lane highway including a bus are studied by using a car following model with a calibrated optimal velocity function. We derive a new flow-density diagram with four distinctly separated traffic states, which is different from that of...

This paper presents an extended intelligent driver traffic flow model, in which the power of the considered vehicle is strengthened in proportion to that of the immediately preceding vehicle. We analyze the stability against a small perturbation by use of the linear stability method for the...

In this paper, we study the effects of intelligent control mechanism on multiple-vehicle collision induced by a sudden stop. The control motion of following vehicles is extended by introducing their velocity relative to the braking one into the dynamic models. We study the dynamic process of...
