I. Introduction
Over the past four decades, autonomous driving technology has garnered significant attention from both academia and industry [1]–[3]. In academia field, various competitions and research projects have driven the continuous development of autonomous driving technology [4]. In industry field, autonomous driving technology has been deployed in a variety of applications, such as Navigate on Autopilot (NOA) [5] [6], open-pit mines [7], and ports [8]. With substantial governmental support, the development of autonomous driving technology has demonstrated promising momentum. Autonomous driving test sites [9], established in various locations have provided platforms for the further verification and enhancement of the technology. In addition, many companies are conducting public road tests to evaluate the performance and safety of autonomous driving technology under real-world road conditions [10] [11].
