In order to solve the traffic problem of mixed platoon of connected and autonomous vehicles and connected vehicles at intersection under the intelligent network environment, a traffic model was built based on Vehicle to Everything(V2X) real-time communication technology, mixed integer programming, branch and bound method. Meanwhile, a simulation system of mixed platoon at intersection under intelligent network environment was established using Simulation of Urban Mobility(SUMO) software for model verification. Taking one typical intersection as an example, the parameters such as average vehicle delay, average stop times and average energy consumption of the model and adaptive traffic signal control system were compared and analyzed. The results showed that under different penetration rates of connected and autonomous vehicles, the model could optimize the vehicle trajectory and signal timing according to the traffic flow conditions, and reduce the stop times by 90%~94%, vehicle delay by 20%~30%, and energy consumption by 10%~15% respectively; with the increasing of the penetration rate of autonomous vehicles, the influence of the acceptance probability of speed suggestions of networked vehicles was weakened, and the optimization effect of the model was increased.
