Although automated vehicles are becoming more popular due to the development of technology, semi-automated vehicles with auxiliary devices such as automatic braking and Adaptive Cruise Control(ACC) are now the mainstream. On the other hand, fully automated vehicles are expected to improve safety and fuel economy by providing optimal driving by a machine compared to semi-automated vehicles. This paper (1) compares previous traffic method, Autonomous Intersection Management(AIM) and Virtual Traffic Light(VTL), and (2) proposes a new traffic control scheme Dynamic Virtual Traffic Light (D-VTL), which could be replaced to VTL and improve 29% traffic efficiency in AIM4 simulation.
