Abstract: Connected autonomous vehicles (CAV) are currently under development, and the mixed flow with CAV would make the traffic states more complicated. Due to the lack of mature applications, the future traffic with CAV are still full of uncertainties. Under the new situation, the traditional cellular automata (CA) model is in need of upgrade. To discover the characteristics of traffic flow under different CAV penetration rates, and considering the particularity of the ramp segments on freeway, this paper updates the current CA model and analyzes the car-following and lane-changing behavior of mixed traffic flow under the intelligent network. Results show that, as the CAV penetration rate continues to increase, the road operation performance continues to improve, and the capacity of the road segment increases accordingly.
