Based on intelligent traffic system idea and fuzzy logical, a fuzzy control method of the traffic light signal with full countdown function is proposed which can effectively solve the randomness problem in the dynamic system. The method overcomes limitation of traditional mathematical control method and does not build a complex traffic flow model. It makes the action of controlling green light time into a series of roles and these roles can be optimized off-line. This paper studies the deviation in traffic flow data and data bottleneck production problem, and provides a solution based on conjunction of mathematical statistics and time series analysis. Using the conception of flow quantitative to fuzz traffic flow to implement self-adapted fuzzy controller controls intersection signal.
