Abstract — This research is motivated by problems with traffic light as traffic signs which in several cases and certain places have not been able to overcome the problem of traffic jams which continue to occur accompanied by the rate of growth and population density in Indonesia. The traffic light system that is generally used today is the Fixed Time Traffic Light Controller, which in reality is less effective for this problem. For this reason, this research developed an Automatic Traffic Light System Based on Vehicle Queue Length with Image Processing with the aim of helping reduce congestion that occurs at intersections, by processing information through a working system on a computer. By using Image Processing, Python, Yolo, Matlab and going through testing stages, it can be concluded that the system can run and detect vehicles on every road lane. From overall car detection on each road section in five tests , it was found that the systems accuracy rate for detecting cars was 81%, and motorbike detection was 54%.

Abstract
This paper is based on the first principles of density functional theory and uses the virtual crystal approximation method to calculate and analyze the optical properties of differently proportioned Eu3+-doped Bismuth silicate (Bi4Si3O12, or BSO). The results show that minor Eu3+ doping (1/12–1/3) improves the polarization ability of BSO and reduces energy loss. Additionally, doping an appropriate amount of Eu3+ (1/12–1/3) can improve light absorption and transmission of BSO to some extent. That is to say, Eu3+ doping improves the response of BSO to infrared light, and the absorption capacity in the ultraviolet and visible light regions is also enhanced. The theoretical research in this paper elucidates the changes in the optical properties of BSO after doping with Eu3+, providing a theoretical basis for expanding its application as a scintillation crystal in high-energy physics experiments, nuclear medicine, and other fields.
