Abstract

Taking practical and effective traffic prediction and control measures to ease highway traffic congestion is a significant issue in the research field of Intelligent Transportation Systems (ITS). This paper develops a Hierarchical Fuzzy Rule-Based System (HFRBS) optimized by Genetic Algorithms (GAs) to develop an accurate and robust traffic congestion prediction system employing a large number of input variables. The proposed system reduces the size of the involved input variables and rule base while maintaining a high degree of accuracy. To achieve this, a hierarchical structure composed of FRBSs is optimized by a Steady-State GA, which combines variable selection and ranking, lateral tuning of the membership functions, and optimization of the rule base. We test the capability of the proposed approach on short term traffic congestion problems, as well as on benchmark datasets, and compare the outcomes with representative algorithms from the literature in inferring fuzzy rules, confirming the effectiveness of the proposed approach. © 2014 Elsevier Ltd.
