The application of Fuzzy Control in the intelligent crossroad traffic control

摘要

Considering the complexity,uncertainty,randomness of the city crossroad traffic,it is very difficult to structure precise mathematic model,the traditional traffic theory and method applied in the city traffic control cannot deal with it efficiently.However the fuzzy control can handle it intelligently without precise mathematic model,as it can make decision just like people thinking in brain.Based on the practical experience,it has a big application prospect in intelligent city traffic control.According to the development of Fuzzy Control,we summarized the basic composing and design approach of Fuzzy Control.Finally we introduced the design of the intelligent crossroad traffic control.Compared with the simulation of fixed control,we found that the performance and parameter were improved based on the Fuzzy Control.
