Cyber‐physical description and CPS‐based pinning approach of mixed traffic

Abstract

Abstract In this paper, a cyber‐physical description of mixed traffic that can reflect the interaction between vehicles is first proposed. By treating vehicles as nodes and the cyber‐physical interaction between vehicles as directed edges between nodes, the network of vehicles in traffic is obtained. The small‐world and scale‐free characteristics of mixed traffic are found under this description. Then the CPS‐based pinning approach for achieving indirect control of HVs is proposed. Besides the control algorithm of pinning nodes, the impact of the spatial distribution of automated vehicles on traffic is studied. The approach is compatible with the existing control of automated vehicle in mixed vehicle platoon. Numerical simulation results under three‐lane scenario illustrated the effectiveness of the proposed pinning approach.
