This document summarizes a research paper that proposes a simulation-based automatic traffic controlling system. The system uses image processing and algorithms like SCOOT (Split Cycle Offset Optimization Technique) or UTC (Urban Traffic Control) to determine optimal traffic light timing based on real-time vehicle counts. It aims to reduce traffic congestion and waiting times by adapting light cycles dynamically. The system prioritizes lanes with emergency vehicles by stopping other lanes. It was tested in simulations of a four-way intersection with results showing promise for improving traffic flow. Further work is needed to coordinate traffic lights across multiple intersections.
