T/SHJX 023-2021 Vehicle-road Collaborative System Dynamic Digital Map Application Layer Dataset Technical Requirements

Scope

Scope: This document specifies the technical requirements for application-layer data sets in the context of vehicle-road collaboration systems, focusing on the dynamic data of high-precision maps and the data exchange between various application platforms. This document applies to the dynamic data exchange of high-precision maps in vehicles under vehicle-road collaboration systems. Main technical content: 1. Basic architecture: The basic architecture is the foundation of this standard. This architecture revolves around the vehicle-road collaboration cloud control system, and also includes third-party data systems, infrastructure systems, and map vendors. Based on the four-layered architecture of cloud, management, roads, and terminals, it forms a vehicle-road collaboration system for dynamic map information exchange. This standard specifies the main logical functional entities of the basic architecture and the interface relationships and definitions between these entities. 2. Typical scenarios of dynamic digital maps: Since this standard involves the technical requirements for application-layer data sets, it is necessary to first clarify the application scenarios covered by this standard before formulating the application-layer data sets. For the current applications of dynamic information of high-precision maps in urban roads, highways, and closed roads, we have sorted out 17 typical application scenarios of dynamic digital maps from multiple perspectives and dimensions, including road conditions, weather conditions, signs and markings, operating vehicles, closed venues, intersections/ramps, ports, etc., and provided descriptions and interaction processes of these typical scenarios. 3. Data sets of dynamic digital maps: For the 17 typical application scenarios sorted out, we define the application-layer data sets between various systems in different scenarios, involving various data elements and specific descriptions required by various applications, and give o
