V2X communication technology can overcome the limitations of existing Lv. 3 autonomous vehicles by recognizing surrounding traffic conditions and road hazards beyond the recognition range of ADAS sensors, and its necessity is gradually increasing as a key technology for implementing Lv. 4 or higher autonomous driving. Major countries around the world (Europe, China, Japan), including Korea, are paying attention to accident prevention safety using V2X technology and have established a roadmap for the New Car Assessment Program (NCAP) and are introducing V2X technology as an NCAP evaluation item. In this study, we conducted research on the development of vehicle V2X communication performance safety evaluation technology, including evaluation items, evaluation environment, and evaluation method for evaluating the performance of congestion control technology of V2X communication devices installed in vehicles in an environment where V2X technology is applied to actual roads and numerous vehicles and infrastructures communicate simultaneously, resulting in communication congestion and V2X communication performance degradation.
