Feedback control scheme for traffic jam and energy consumption based on two-lane traffic flow model

In this paper, a coupled map car-following model is extended to two-lane traffic system. Based on it, the numerical simulations for one stop and series stops situations are performed respectively under the open boundary condition. The evolution of traffic jam and corresponding energy consumption are then explored and compared each other. Additionally, the influences of the lane changing rule and control scheme on traffic jam and energy consumption are investigated separately. The results show that lane changing rule and control scheme are found not only to suppress the traffic jam but also to reduce the energy consumption. The control scheme exhibit better behavior than lane changing rule does in suppressing traffic jam and reducing energy consumption in two-lane traffic system. The outputs of these findings demonstrate the potential of the proposed model to be applicable to evaluate the control schemes for suppressing traffic jam and reducing energy consumption in real traffic condition.
