Short description
Included in this set are the SAE J2945/A Recommended Practice which specifies the minimum requirements for defining various road geometries and select attributes associated with them via the Road Geometry and Attributes (RGA) data set (DS) to support road geometry related motor vehicle safety applications. Contained in this report are a concept of operations, requirements, and design, developed using a detailed systems engineering process. Utilizing the requirements, the RGA DS is defined, which includes the DS Abstract Syntax Notation One (ASN.1) format, data frames, and data element definitions.
