Abstract

Urban traffic congestion is increasing rapidly due to the growing number of vehicles and the continued use of fixed-time traffic signal systems. Conventional traffic signals operate with predefined timings and do not consider real-time traffic conditions, which results in longer waiting time and inefficient traffic flow. This paper presents a computer vision-based adaptive traffic signal control system that dynamically adjusts signal timings according to real-time traffic density. Vehicle detection and counting are performed using the YOLO object detection model with OpenCV. Lane-wise traffic density is calculated and used to control signal duration automatically. Experimental observations show that the proposed system improves traffic movement and reduces congestion when compared with traditional fixed-time traffic signal systems.

Keywords

Adaptive Traffic Signal, Computer Vision, YOLO, OpenCV, Traffic Analysis.

Conclusion

This paper presented a computer vision- based adaptive traffic signal control system using YOLO and OpenCV. By adjusting signal timings based on real-time traffic density, the proposed system improves traffic efficiency and minimizes congestion. The system provides a practical solution for intelligent traffic management in urban environments.
