Design of Traffic Light Controller using Verilog HDL

Abstract

The traffic at road crossings and intersections is regulated by turning on and off the red, green, and yellow lights in a certain order. The Traffic Light Controller is meant to create a series of digital data known as switching sequences, which may be used to operate the traffic lights of a conventional four-way intersection in a predetermined order. It is also recommended that day and night operations be implemented. It is becoming more crucial in modern urban traffic management and control in order to decrease road accidents and traffic jams. It is a sequential machine that must be examined and programmed in several steps. Analysis of current sequential machines in traffic light controllers, timing and synchronization, and the introduction of operation and flashing light synthesis sequences are all part of the device. Design the circuit, write code, simulate, synthesize, and implement in hardware are the approaches utilized in this project. Quartus Prime 18.1 Software was selected for this project to create a schematic using schematic edit and write code using the Verilog HDL (Hardware Description Language) text editor.
