Fuzzy logic is a figure of multi-valued logic, which derived from fuzzy set theory to deal with approximate reasoning rather than precise. A fuzzy logic approach application can optimize multiplex goals and then reach a nearer similarity to the real world. Modeling of incorrect scheduling knowledge is permitted by fuzzy logic, with linguistic variables, which defined via membership functions showing the accuracy degree of the data and the reasoning about the incorrect data by using fuzzy rules. Fuzzy logic that was introduced by Zadeh (1965) has been utilized to several industrial problems. Fuzzy logic system approach privilege is incorporating both numerical results from a previous solution or simulation and the scheduling expertise from experiences or observation, and that’s convenient to implement.
Fuzzy logic is shown to be a very promising mathematical approach to modeling traffic and transportation processes characterized by subjectivity, ambiguity, uncertainty and imprecision. The basic premises of fuzzy logic systems are presented as well as a detailed analysis of fuzzy logic systems developed to solve various traffic and transportation engineering problems. Emphasis is put on the importance of fuzzy logic systems as universal approximators in solving traffic and transportation problems. Possibilities are shown regarding the further application of fuzzy logic in this field.
