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...

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...

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...

Membrane fouling is generally considered as a major bottleneck to the wide application of membrane bioreactor (MBR) for high saline mariculture wastewater treatment. Though numerous researches have investigated the membrane fouing of MBR combined with bio-carriers, few studies reveal the impacts...

In online outsourcing platforms where clients (buyers) can procure diverse services from freelancers (service providers), skill certification systems are usually offered for freelancers to signal their private service expertise. This study considers a multi-stage online outsourcing context where...

Motivated by challenges facing IT procurement, this paper studies a hybrid procurement model where a reverse auction of a fixed-price IT outsourcing contract may be followed by renegotiation to extend the contract's scope. In this model, the buyer balances the need to incentivize...
