A new continuum model with consideration of driver’s forecast effect is obtained to study the density wave problem and the stop-and-go phenomena. The stability condition of the new model is derived by using linear analysis. The triangular shock wave, one type of density wave, which is determined by Burgers equation in the stable region, is discussed in great detail with reductive perturbation method. The local cluster appears when we perform the numerical simulations for the new model. It also proves that the driver’s forecast effect has the positive effect of reducing the local cluster.

The Stability

PurposeTo reflect the future traffic environment, the authors simultaneously incorporate the electronic throttle (ET) and traffic jerk into the traditional continuum model. The authors derive the stability criterion of the enhanced continuum model via the perturbation method.Design/methodology/approachTo facilitate insight into the propagation and evolution mechanism of traffic jam near the stability condition, the authors use the nonlinear stability analysis method to derive the KdV-Burgers equation of proposed continuum model. Finally, the numerical example verified that the new item of ET opening angle and traffic jerk have a positive impact on suppressing traffic congestion and improving road robustness.FindingsThe new item of ET opening angle and traffic jerk have a positive impact on suppressing traffic congestion and improving road robustness.Originality/valueTo better reflect the real traffic environment, a extend continuum model taking into account the ET opening angle and traffic jerk effect is presented. The stability criterion of the extended model is got based on perturbation method. The evolution characteristics and propagation mechanism of the traffic jam near the neutral stability condition are further received by deriving the KdV-Burgers equation in the nonlinear stability analysis. From simulation, we found that the ET opening angle information and traffic jerk have a significant effect on the traffic jam.
