With the popularization of scenarios where intelligent connected vehicles (ICVs) and human-driven vehicles (HDVs) coexist, the current high-priority vehicle traffic strategy is difficult to effectively play a role in mixed traffic flow. Therefore, a reinforcement learning based method is proposed. Firstly, use SUMO to build the model. Secondly, the Proximal Policy Optimization (PPO) algorithm is adopted to adjust the longitudinal speed of ICVs, the longitudinal spacing between basic units of sparse heterogeneous mixed traffic flow, and collaborate with high-priority vehicles to change lanes and overtake. Finally, validate the model in different scenarios. The results indicate that this method is suitable for scenarios with heterogeneous mixed traffic flow and full ICVs; Compared to the lane pre-clearance strategy, this strategy reduces the passing time of high-priority vehicles by 17.39% and 5.09% in distance, respectively; The overall number of lane changes has decreased by 75%, significantly reducing the impact on weekly traffic.
