Modeling and Analysis of Hybrid Traffic Flow Considering Actual Behavior of Platoon
To explore the effect of actual behavior of autonomous vehicular platoon on traffic flow,aiming at the hybrid traffic flow mixed with predecessor following(PF)platoon which is modeled according to the actual control strategy,a hybrid traffic flow model is established based on cellular automata(CA)modeling method.Simulation analysis shows that the effect of platoon characteristics such as time headway,market penetration,platoon size,and control gains on hybrid traffic flow presents coupling and nonlinear properties.The spatiotemporal behavior of hybrid traffic flow with different platoon characteristics is generally much different.Reducing time headway or increasing platoon market penetration is generally beneficial to enhance road capacity.The consistent laws of the effect of platoon size and control gains on traffic flow are not obvious,which must be combined with other platoon characteristics to carry out the analysis.
