随着社会的飞速发展和科技的不断提升，为我们带来了很大的便利和幸福感。就

With the rapid development of society and the continuous improvement of technology, it has brought us great convenience and happiness. For example, in terms of cars, we are now experiencing the convenience it brings, but with the increasing number of cars, it brings us convenience and many other drawbacks. For example, traffic jams, traffic accidents and so on. Therefore, the place occupied by traffic control on daily urban roads is becoming more and more important, and the use of traffic lights at busy intersections has therefore received more and more attention. This research uses Verilog hardware description language to design the traffic signal light control circuit. The purpose is to design an effective red, yellow and green light control system, which can be universally applied to the intersection of main and branch roads with different road conditions. The design plan rationalizes the color change sequence and time interval of traffic lights. This research also uses QuartusⅡ 15.0 software to conduct simulation experiments on the designed control system, observe the characteristics of the waveform, and then write the set program into the FPGA, and finally realize the predetermined function and have a certain practicability.

With the rapid development of society and the continuous improvement of science and technology, for us to bring great convenience and happiness. In the case of cars, for example, we are now experiencing the conveniences it brings, but with the increasing number of cars, it brings us convenience and many other disadvantages. For example, traffic jams, traffic accidents and so on. Therefore, traffic control on the city's daily roads occupies an increasingly important position, in the crossroads of the car water Malone, the use of traffic lights has been more and more attention. In this study, the traffic light control circuit is designed using Verilog hardware description language, in order to design an effective red, yellow and green light control system, which can be generally applied to the main and branch intersections with different road conditions, and to design and plan for this, so as to rationalize the color change order and time interval of traffic lights. In this study, the designed control system is simulated and simulated by Quuartus II 15.0 software, the characteristics of the waveform are observed, and the set program is written into the FPGA, and the predetermined function is finally realized, and it can have some practicality.

With the rapid development of society and the continuous improvement of science and technology, it has brought us great convenience and happiness. For example, in the aspect of automobile, we are now experiencing the convenience it brings, but with the increasing number of cars, it will bring us convenience as well as many other disadvantages. For example, traffic jams, traffic accidents and so on. Therefore, in the city's daily road traffic control occupies an increasingly important position, in the busy intersection, the use of traffic lights is also more and more attention. This study uses Verilog hardware description language to design the control circuit of traffic lights. The purpose is to design an effective control system of traffic lights, which can be widely applied to the main and branch road intersections with different road conditions, and to design and plan it, so as to rationalize the color transformation order and time interval of traffic lights. This research also uses Quartus Ⅱ 15.0 software to simulate the designed control system, observe the characteristics of the waveform, and then write the set program into FPGA, finally achieve the predetermined function, and can have a certain practicality.<br>
