Abstract

En 中文

• Hybrid approach combining RL-based offset control and rule-based green phase split. • Linking reward function to delay minimization, grounded in Little’s Law. • Capturing offset-split interdependency by simultaneous and joint control. • Considering neighbor intersections in reward for network-wide coordination.
