T/ITS 0037-2015 Cooperative Intelligent Transport System (CITS) Road Information Structuring and Interactive Dataset Specification
Basic Information
Scope
Scope: This standard applies to converting complex dynamic and static information related to roads, facilities, motor vehicles, pedestrians, non-motor vehicles, and traffic incidents into computer-processable logical and structured data; and standardizing the communication formats and parsing methods for the interaction of the aforementioned data among various entities of the system, thereby enhancing the compatibility of cooperative intelligent transportation systems. Main technical content: This standard specifies how to structurally express, store, interact, and use macroscopic and microscopic road information in cooperative intelligent transportation systems, covering road segment connection relationships, traffic light phase information and real-time status information, and the physical and logical road information such as traffic light and turn signal correlation relationships. Through the structuring of road information, a series of road information units are defined at different levels, and on this basis, the storage formats and interaction norms of each unit are defined.
