According to @ai_darpa, autonomous traffic cones equipped with AI and solar power are now deploying themselves on highways at night in China, eliminating the need for human workers during setup and ensuring precise safety zone alignment. This application of robotics and AI not only improves road work efficiency and safety but also reduces labor costs and operational risks for infrastructure companies. The use of solar-powered, self-moving cones demonstrates a practical and scalable business opportunity for smart city and urban tech providers seeking to modernize traffic management solutions (source: @ai_darpa, Dec 20, 2025).
