SAE J2945/A Road Geometry

Title

Minimum Requirements for Road Geometry and Attributes Definition

Document #

SAE J2945/A

Description

The document provides a generalized mapping solution that can be applied to future infrastructure-based application standards using a layering approach, so that each new application standard at most needs to define a new layer of information that is unique to specific V2X application. It provides an ability to describe small, lane-level map descriptions that apply directly to V2X applications such as reduced speed zones (e.g. work zones) and curves (e.g. curve speed warning).
