This paper gives a traffic signal controller based on FPGA design, it is to use emerging from up to down electronic design method instead of traditional electronic design scheme, with software design technology to achieve the function of the system, realize the integration of the system and intelligent control. At present in the city as the sun vehicles to soar the urban traffic more and more attention. So to design a high degree of integration can be intelligent control of traffic signal control system is particularly important to this. This design using QuartusII software, with programmable logic devices FPGA as the core, completed the design of the input, comprehensive, timing, validation, function simulation, download the whole process of the hardware. The experimental results show that the design is very strong practicability and popularize value.
