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.

Access		Satellite Broadcast Alternatives	A set of alternative standards that includes all satellite-based wireless broadcast technologies.
Facilities	IETF RFC 7230	Hypertext Transfer Protocol (HTTP/1.1): Message Syntax and Routing	This standard (RFC) defines the main Application Layer protocol used for the world-wide web.
Facilities	W3C XML	Extensible Markup Language (XML) 1.0 (Fifth Edition)	This standard defines a generic markup language that can be used to share customizable information by using start and stop tags within the text.
Facilities	SAE J2354	Message Sets for Advanced Traveler Information System (ATIS)	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	Data Dictionary for Advanced Traveler Information Systems (ATIS)	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: Low

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.

Issues

Issue	Severity	Description	Associated Standard	Associated Triple
Encoding rules not defined	High	The standards do not unambiguously define which set of encoding rules to use.	(None)	(All)
Exception handling not defined	Medium	The dialogs do not define how to handle exceptions (e.g., error codes, permission denied, etc).	(None)	(All)
Performance not fully defined (medium)	Medium	The performance rules are not fully defined for this information flow.	(None)	(All)
Data not defined in standard format	Low	The definition of data concepts should conform to ISO 14817-1 to promote reuse among ITS.	SAE J2353 ATIS DD	(All)
Ubiquitous broadcast technology	Low	With the continual enhancement of broadcast technologies and a mixture of free and subscriber-based systems, it is difficult to identify any single technology that can be used to reliably reach the bulk of drivers in a timely manner.	(None)	(All)
