The application of Unmanned Aerial Vehicle(UAV)technology has significantly advanced the development of China's intelligent highway network.The base stations of UAV,critical to the system,play a pivotal role in its functionality,affecting the efficiency and emergency handling capabilities of the entire network.This study innovatively addresses the limitations of drones'endurance and real-time communication range by developing a siting model for drone bases across various highway sections.The model,optimized with a Greedy Randomized Adaptive Search algorithm,enhances emergency response speed and provides strategic support for intelligent highway emergency management systems,marking a significant step forward in the development of intelligent expressways.
