There are a large number of combinatorial logic resources in FPGA, can complete the design of combinational logic circuit, larger scale. Microcontroller design of intelligent traffic light control system, change of state control signal by SCM, basically can be specific traffic directing traffic. Intelligent transportation system is a general term of various high-tech field of transportation system. The paper presents development of intelligent traffic control system based on FPGA and single chip microcomputer technology. Finally, experiments show the efficiency of the design of the intelligent transportation system.
