Research on mixed traffic flow model based on multi-node bilateral control model and chain stability analysis

Abstract

With the development of wireless communication technology, vehicles can obtain more vehicle status information on the same road. From the control point of view, when the vehicle control needs to use the state information of a plurality of surrounding vehicles, it becomes an important problem to determine the weighting coefficients of the information of these different vehicles. Moreover, different vehicle status information should have different weight coefficients. In this paper, Gaussian curve is introduced as the objective function and the shape of curve is adjusted by parameters to determine the weight coefficients of vehicle nodes more flexibly. On this basis, considering the characteristics of multi-node bilateral control, bilateral control, and car-following control, a scalable hybrid control block model (CBMBC) is proposed. And the necessary condition of chain stability of the proposed bilateral hybrid control block scheme is given. Finally, the effectiveness of the proposed scheme is verified by simulation.
