Situation-cognitive traffic light control based on object detection using YOLO algorithm

Abstract

Current traffic lights provide the green signal with fixed-time interval without considering the traffic situation. As a result, cars in a long line have to wait long time, which causes traffic jams and makes the drivers be irritated. In order to solve the problem, it is necessary to control the green signal interval according to the analysed traffic volume using the image processing and the machine learning techniques. This paper presents a situation-cognitive traffic light control algorithm that measures the traffic volume using object detection algorithm called you only look once (YOLO) and controls the traffic signal intervals according to the traffic volume. The algorithm expects the smooth traffic flow and the reduction of the driver's stress.
