Abstract: Aiming at the problem that it is difficult to implement the dynamic optimization for traffic signal in traffic signal machine, a self-adaptive intelligent traffic signal machine system based on dual Multi Controller Unit(MCU) is proposed, and the structure and operating principle of which is introduced clearly. This paper also expatiates the design of the software and hardware of the system. The optimal object of the system is to minimize average vehicle delay to realize self-adaptive control with real-time fuzzy methods. Experimental results show this system has higher integration, powerful functions, reliable performance, and it is convenient to achieve the traffic network coordinated control.

Key words: _{intelligent traffic signal machine,} C8051F singlechip, fuzzy control, self-adaptive control
