Traffic control at intersection with linear traffic lights

We propose a new device for controlling traffic in intersection, named linear traffic light. The linear traffic light detects vehicles entering the intersection and shows personalized traffic signal to them by linearly aligned traffic lights. The main features of the traffic control system based on the linear traffic light are its simplicity and reliability. In contrast to the other newly developed traffic control systems, the systems with the linear traffic light are implementable only with highly reliable and mature technologies. And, the system does not depend on neither vehicle-to-vehicle communication nor self-localization, which is relatively difficult and whose reliability is crucial in other newly developed traffic control strategies. In this paper, the design of linear traffic light and a traffic control strategy for a simple intersection are shown. Also, the implementability and effectiveness of the linear traffic light are verified through an experiment with prototype miniature traffic control system.
