摘要：
A microscopic traffic flow model was proposed based on a traditional car-following model with the consideration of the effects of multiple preceding cars’ velocity and acceleration；then the parameters of car-following models were calibrated on the basis of the vehicle trajectory；Subsiquently，the impact of multiple preceding vehicles information on traffic safety and efficiency were also investigated；finally，the influence of cooperative adaptive cruise control（CACC）vehicles on traffic safety and efficiency with different penetration rates were also studied. Simulation results prove that except for the immediately preceding vehicle，multiple preceding vehicles’information in the control strategy of the CACC system would have an impact on the following vehicle；the consideration of the velocity and acceleration of multiple preceding vehicles can improve traffic safety and efficiency；the impact of CACC on traffic safety and efficiency was highly related to the penetration rate and arrangement of CACC vehicles. © 2022 Science Press.
