Fuzzy Logic in Traffic Engineering: A Review on Signal Control

Abstract EN

Since 1965 when the fuzzy logic and fuzzy algebra were introduced by Lotfi Zadeh, the fuzzy theory successfully found its applications in the wide range of subject fields.

This is mainly due to its ability to process various data, including vague or uncertain data, and provide results that are suitable for the decision making.

This paper aims to provide comprehensive overview of literature on fuzzy control systems used for the management of the road traffic flow at road junctions.

Several theoretical approaches from basic fuzzy models from the late 1970s to most recent combinations of real-time data with fuzzy inference system and genetic algorithms are mentioned and discussed throughout the paper.

In most cases, fuzzy logic controllers provide considerable improvements in the efficiency of traffic junctions’ management.
