WebNov 25, 2024 · In a traditional signal control mechanism, according to the eight traffic flows as shown in Figure 3 a, there are four signal phases, consisting of north-south bi-directional straight paths, east-west bi-directional straight paths, north-east and south-west left turnings, and west-north and east-south left turnings. WebThe traffic signal operates by allotting green time to the intersection approaches according to a chosen scheme or algorithm. The manner in which green time is allotted to these approaches has been the subject of much consideration and research. a) Pretimed: The traffic signal provides a fixed amount of green time to each approach during a cycle. WebExperimental results show that the traffic signal control method based on Deep Q-Learning Network (DQN) Algorithm is superior to other methods. It reduces the average waiting time of vehicles by 26.7% and decreases the queue length, which greatly improves the road efficiency of the intersection. great western honda statesville
