FSM based Coordinated Four-Way Intersection Specific Automated Traffic Light Controller

Efficient traffic management is crucial for maintaining smooth and safe flow at busy intersections. The FSM controller employs a modular and deterministic approach to traffic signal control. It utilizes a set of well-defined states and transitions to adaptively respond to real-time traffic conditions. The system incorporates various sensors, including vehicle detectors, pedestrian sensors, and traffic flow monitors, to gather input data for accurate decision-making. The FSM model is designed to accommodate different traffic patterns and prioritize the movement of vehicles and pedestrians. It dynamically adjusts signal timings based on the detected demand, considering factors such as vehicle queues, waiting times, and pedestrian crossings. By intelligently coordinating traffic movements, the controller aims to minimize delays, maximize throughput, and improve overall intersection efficiency. To validate the effectiveness of the proposed controller, extensive simulations and comparative analyses are conducted using realistic traffic scenarios. Performance metrics, including average delay, queue length, and throughput, are measured and compared against traditional fixed-time signal control systems. The results demonstrate that the FSM-based automatic traffic light controller offers significant advantages in terms of responsiveness, adaptability, and efficiency. It effectively mitigates congestion, reduces travel times, and enhances the safety of both vehicles and pedestrians at the intersection.
