Abstract Traffic light control is an issue that metropolitan cities are confronted with because of ever-increasing vehicles growth. A proper timing strategy can release the congestion level and minimize vehicle delays better than standard fixed signal timing (FST) strategy. In this paper, a self-adaptive Q-learning based traffic light green time control strategy (QTGCS) is designed to reduce the congestion. Q-Learning acts as the learning mechanism for light at each intersection as an independent agent to release itself by operating traffic light duration dynamically. Q-Learning is based on discrete representation of state and action spaces. In order to make QTGCS not independent of the environment and designer criterion, Fuzzy Q-learning based traffic light green time control strategy (FQTGCS) is proposed by applying the fuzzy logic control to optimize timing strategy based on the number of vehicles receiving from the adjacent intersections. We show through simulation that our algorithm effectively over the real road networks.
