US: ATIS - Wide Area Broadcast

Description:

This solution is used within the U.S.. It combines standards associated with US: ATIS with those for C-X: Wide Area Broadcast. The US: ATIS standards include upper-layer standards required to implement traveler information communications. The C-X: Wide Area Broadcast standards include lower-layer standards that support one entity broadcasting information to all wireless devices over an area that covers at least a metropolitan area without any expectation of acknowledgement or response; security is provided by the upper-layers.

Comm Profile: C-X: Wide Area Broadcast

Standards in Profile:

Level	Standard	Description
Access	WAW Broadcast Alternatives	A set of alternative standards that describes various types of wide-area wireless broadcast mechanisms.
Mgmt	Proprietary	A proprietary mechanism to provide services for this layer.
Security	Proprietary	A proprietary mechanism to provide services for this layer.
TransNet	Proprietary	A proprietary mechanism to provide services for this layer.

Level	Doc #	Standard	Description
Facilities	IETF RFC 9110	IETF RFC 9110 HTTP Semantics	The Hypertext Transfer Protocol (HTTP) is a stateless application-level protocol for distributed, collaborative, hypertext information systems. This document describes the overall architecture of HTTP, establishes common terminology, and defines aspects of the protocol that are shared by all versions. In this definition are core protocol elements, extensibility mechanisms, and the "http" and "https" Uniform Resource Identifier (URI) schemes.
Facilities	IETF RFC 9112	IETF RFC 9112 HTTP/1.1	The Hypertext Transfer Protocol (HTTP) is a stateless application-level protocol for distributed, collaborative, hypertext information systems. This document specifies the HTTP/1.1 message syntax, message parsing, connection management, and related security concerns.
Facilities		Presentation Format Alternatives	A set of alternative standards for formatting that can be used for data presentation.
Facilities	SAE J2354	SAE J2354 ATIS Messages	This standard defines how to exchange data for Advanced Traveler Information Systems (ATIS). The messages contained herein address all stages of travel (pre-trip and en-route), all types of travelers (drivers, passengers), all categories of information, and all platforms for delivery of information (in-vehicle, portable devices, kiosks, etc.).
ITS Application Entity	SAE J2353	SAE J2353 ATIS DD	This document provides a set of core data elements needed by information service providers for Advanced Traveler Information Systems (ATIS). The data dictionary herein provides the foundation for ATIS message sets for all stages of travel (pre-trip and en route), all types of travelers (drivers, passengers), all categories of information, and all platforms for delivery of information (in-vehicle, portable devices, kiosks, etc.). The elements of this document are the basis for the SAE ATIS Message Set Standard J2354 and are entered into the SAE Data Registry for ITS wide coordination.

Readiness Description:

One serious or several significant issues. This category often includes proprietary or partial solutions. The communications solution may fail to provide even a base level of interoperability and security. Consider alternative solutions, or define specific revisions or upgrades that would provide a level of interoperability or security that are needed for the deployment.
