Informatization, digitalization and intelligence are key characteristics of high-quality development in the transportation industry, and data elements are the new driving forces for the development of transport. Data standardization is a fundamental task in the development of digital transportation, and it is crucial for ensuring that information systems achieve information sharing, interconnection and business collaboration. The compliance testing of data standards promotes data standardization and quality management, which is of great significance for promoting data fusion applications and business system collaboration and linkage. This paper reviews the current state of compliance testing both domestically and internationally and summarizes the key aspects of data standard compliance testing, including the subjects, content, processes, standards and platform tools. It analyzes the current state of compliance testing research in the transportation industry and offers development suggestions to support the optimization and upgrading of data standard compliance testing work in the transportation industry information systems.
