摘要
In order to construct the traffic mechanism and control method of the intersection under the mixed traffic of connected and autonomous vehicles (CAV) and human drive vehicles (HDV), the paper proposed a cooperative traffic model for intersections under the conditions of CAV dedicated lanes. First, an intersection layout under the condition of CAV dedicated lanes is designed, and the intersection space is grid-processed. The occupancy of a particular part of the grid at the intersection for a certain period by the CAV and HDV is unified under the intersection space-time resource description framework. Second, a space-time resource allocation model is established considering both CAV and HDV. An adaptive signal light control algorithm and a CAV trajectory planning algorithm are proposed. Third, adaptive signal light timing and CAV trajectory are optimized to achieve minimum vehicle delay. Finally, the effectiveness of the proposed method is verified by selecting a typical intersection in Guangzhou to establish a simulation experiment. ? 2023 South China University of Technology.
