On account of the traffic flow with the high complexity and randomicity, we could adopt fuzzy theory and fuzzy control technology without setting up an accurate math model, which can avoid the unideal control effect, brought by inaccurate math model, and also can adapt the real-time control. Therefore, this paper applies the fuzzy theory and fuzzy control technology to research and discuss traffic control.
