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.

| 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.
