Cellular Automata for Four-Lane Circular Traffic System

This MATLAB-based program implements a cellular automata model to simulate a four-lane circular traffic system. The primary objective is to help users understand traffic system dynamics, particularly how peak-hour traffic flows impact road capacity. The simulation employs discrete grid-based movement algorithms where each cell represents a road segment, with vehicles transitioning between states according to predefined rules. Key features include vehicle flow modeling using velocity update functions, traffic light control through timing cycle algorithms, and congestion simulation via density calculation methods. The program enables testing of various traffic management strategies such as speed limitations (implemented through maximum velocity parameters), lane configuration adjustments (via lane-changing probability functions), and intersection signal optimization (using phase timing controls). The code structure includes initialization modules for road network setup, main loop functions for state updates, and visualization components for real-time traffic display. Overall, this program serves as a valuable tool for understanding and managing traffic systems through computational modeling approaches.
