In order to ensure the interconnection and interoperability of business data during vehicle operation, and improve the high reliability and safety of vehicle road collaborative services, this paper studies the collaborative sharing technology scheme of vehicle road collaborative infrastructure data. This paper introduces four high-value use cases of vehicle road collaborative infrastructure data collaboration and sharing, analyzes their requirements, and explores the reference architecture for vehicle road collaborative infrastructure data collaboration and sharing. In addition, this paper proposes two technical schemes for data collaborative sharing, including those based on edge computing platform, cloud platform and other methods, and defines the data request, authentication and sharing process. Finally, this paper comprehensively considers the supported services, synchronization latency, requirements for network and edge platforms, and analyzes the feasibility and challenges of different sharing schemes, providing new ideas for achieving data collaboration and sharing between different operators.
