Recently, intelligent transportation system (ITS) has been studied for efficient use of road infrastructure. With the advance of transportation systems, traffic signal control methods have been improved from conventional pre-timed signal controls to active strategies that dynamically schedule the traffic signal based on real-time traffic flow. This paper introduces a novel algorithm to minimize average delay and improve throughput for the repetitive traffic congestion that is a critical problem at urban intersections, leading to various problems such as safety reduction, increase of pollution, and so on. In our algorithm, future traffic congestion is estimated using traffic pattern learning based on historical traffic information. We use adjusted correlation coefficient for accurate congestion estimation with previously learned traffic data. To improve the utility of our algorithm, the actuated control is included which has been used widely in real field. In our experiments, the microscopic traffic simulator VISSIM performed our modeling works. The results show that the proposed algorithm has good effect to the intersections struggling with repetitive traffic congestion problems.
