Construction of Autonomous Traffic Light Offset Control System using Multi Agent System

Traffic jam is one of critical issues in urban life. By which, many social problems, for example, time loss, economical loss, and environmental pollution are caused. There are two typical methods for solving traffic jam, improvement of car navigation system and control of traffic lights. We focus on control of traffic lights. Existing traffic light control system is basically centralized control type and lacks robustness and scalability. If the central computer becomes breakdown, all traffic lights received the damage of it. In this paper, we propose a new traffic light control system based on multi-agent model. The offset value, one of the main traffic light parameters, is controlled by using only local information, and green-wave formation is formed through the coordination of each intersection agent.
