Traffic congestions widely exist in the underground transportation of mines, which damage the mobility of traffic system and bring safety hazards. Leveraging the advantages of connected and automated vehicle (CAV) technologies, this study proposes a novel approach for efficiently organizing vehicles in a scheduled manner. With the implementation of vehicle-infrastructure cooperation, CAVs are supposed to travel with the pace of the space-time passages that are designed on each links to fulfill their trips. In addition, vehicle trajectories are elaborately optimized to reduce vehicle delays in their trips under the premise of guaranteeing traffic safety. To validate the performance of the proposed methods, numerical experiments are tested under different traffic demand settings. The results verify that the proposed method could organize the traffic efficiently and in an orderly manner, reflected in eliminating extra delays of CAVs at intersections and guaranteeing collision avoidance concurrently.
