However, these methods have poor warning effect on high-flow road sections, especially at night or in bad weather conditions, the visibility and reaction ability of pedestrians and drivers are greatly reduced. In addition, these devices work continuously throughout the year, with high energy consumption and high maintenance cost, and lack of intelligent management, making it difficult to cope with complex and changing traffic conditions.
