Digital road traffic signs, as a novel technology in modern traffic systems, have opened up new avenues for enhancing road safety and efficiency. This study aims to delve into the signal propagation performance of digital road traffic signs, particularly under various environmental conditions. We conducted both static and dynamic tests to analyze the relationship between signal strength and propagation distance, as well as the impact of device installation height and obstructions on signal propagation. Utilizing state-of-the-art digital traffic sign equipment, including high-performance transmitters and receivers, as well as specially designed vehicle-mounted devices, this study provides a comprehensive assessment of key factors such as transmission power, vehicle speed, and signal reception performance. The test results offer an in-depth understanding of the signal propagation characteristics of digital traffic signs. Through thorough data analysis, this study reveals several key factors affecting signal propagation performance and provides valuable guidance for the design and practical application of digital road traffic signs. Overall, this study underscores the importance of digital traffic signs in future traffic systems and offers strategic recommendations to ensure their effectiveness and reliability.
