Hybrid Traffic Flow Characteristics of Connected and Automated Vehicles and Human-driven Vehicles

摘要

Aiming at the characteristics of the hybrid traffic flow in the intelligent network environment, four kinds of following modes and corresponding following models of the mixed traffic composed of (CAVs) and (HDVs) are analyzed. Then, a basic graph model of the relationship among the flow, density and speed of the mixed traffic flow under the stable state with the permeability of CAVs as the control parameter is constructed. Based on the basic graph model, the relationship between the road capacity of the mixed traffic flow and the penetration rate of CAVs is analyzed. Finally, SUMO simulation data is used to verify the hybrid traffic flow characteristics model. The results show that the flow-density data scatter and the model curve have a high agreement under different penetration rates of CAVs, which verifies the rationality and accuracy of the model.
