Abstract: A novel approach for coordinating connected and autonomous vehicles at intersection is proposed in this paper. The road connecting the specific intersection is divided into two areas: status calculation area and status adjustment area. When the vehicle enters the status calculation area, LOOSE algorithm which is implemented in the infrastructure would be triggered to calculate the target status of the vehicle for it to avoid collision in the intersection. The results of LOOSE would be optimized by COMPACT algorithm with the objective of minimum queue length. And then operational suggestions for the vehicle to move in the adjustment area would be generated based on vehicle kinematic models. Simulation results show that the method is able to improve the capacity of the intersection, especially for balanced traffic flow. And the method performs better than traditional signal control method in reducing the average vehicle delay.

Key words: intelligent transportation, intersection control, slot-based crossing, collision avoidance
