Traffic Signal Control System for Scramble Intersections Using Reinforcement Learning

Developed a system that dynamically controls traffic signals at scramble intersections using deep reinforcement learning. Through simulation-based training, the system optimizes traffic flow and demonstrates reduced waiting times and fewer accidents.

Traffic Signal Control System for Scramble Intersections Using Reinforcement Learning
Overview

This research developed a system that optimizes traffic signal control at scramble intersections using deep reinforcement learning. Various traffic situations were simulated, and the agent learned optimal signal switching timings. Compared to conventional methods, the system demonstrated reduced waiting times and accident risks.
