Abstract
In this article a hierarchical fuzzy logic controller is proposed to tackle this traffic control problem at a two-way road junction with turning traffic. The two levels of fuzzy logic controllers devise the minimum effective green-time and fine-tune it, respectively, at each phase of a traffic-light cycle. The complexity of the controller at each level is reduced with a smaller rule-set. The performance of this hierarchical controller is examined by comparison with a fixed-time controller under various traffic conditions. Substantial delay reduction has been achieved; the performance and limitations of the controller are discussed.
