Abstract
With the acceleration of urbanization, traffic congestion and safety issues have become increasingly prominent, making intelligent transportation an important direction for addressing these challenges. Internet of Things (IoT) technology provides a novel solution for traffic signal control. This study investigates the application potential and optimization effects of IoT technology in intelligent traffic signal control by constructing a real-time data collection and analysis system based on IoT, integrated with edge computing and cloud computing technologies. The system achieves efficient fusion and intelligent decision-making of multi-source data, including traffic volume, vehicle speed, and queue length. A combination of simulation and field testing was employed to validate the system's response speed and control accuracy through the deployment of a sensor network at typical intersections. Results indicate that the system can significantly reduce average delay time, enhance road capacity, and effectively handle unexpected traffic conditions. The innovation of this study lies in the deep integration of IoT technology with adaptive signal control algorithms, proposing a new method for dynamically adjusting signal timing. This provides theoretical support and technical references for the practical deployment of intelligent transportation systems, demonstrating significant practical value and broad application prospects.
