Full Description

This SAE Standard specifies message set requirements for roadside safety applications, including detailed systems engineering documentation (needs and requirements mapped to appropriate data exchanges). The applications include: Curve speed warning (CSW) Reduced speed zone warning (RSZW) Lane closure warning (LCW) Dynamic traveler information (DTI) Incident information (INC) This document defines a new road safety message (RSM) and the use of infrastructure-to-vehicle communications capabilities defined in other standards, including SAE Standards, and the National ITS Architecture. This does not define a single, generic, broadcast application for infrastructure systems, but a message set and structures to support the above listed applications. The new message and its structure enable additional applications to add new material to the common framework that is defined herein. This allows further development and deployment of new applications with new message content in the future. The purpose of this document is to enable roadside safety application interoperability using I2V communications, although its use with V2V and V2X is anticipated and not precluded.
