US: ATIS - Wide Area Broadcast
Description:
This solution is used within Canada and 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.Relevant Regions:
- Canada
- United States
Comm Profile: C-X: Wide Area Broadcast
Comm Class: WAN - Wide Area Network

Solution Issues Severity: 16
The severity issue score calculation only includes issues associated with standards that are included by default.
Solution Issues:
| Default | Severity | Name | Type | Description |
|---|---|---|---|---|
| True | Low | Data not defined in standard format | ITS Info Gap | The definition of data concepts should conform to ISO 14817-1 to promote reuse among ITS. |
| True | Low | Ubiquitous broadcast technology | SubNet Gap | 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. |
| True | Medium | Exception handling not defined | Facility Layer Gap | The dialogs do not define how to handle exceptions (e.g., error codes, permission denied, etc). |
| True | Medium | Performance not fully defined (medium) | ITS Info Gap | The performance rules are not fully defined for this information flow. |
| True | High | Encoding rules not defined | Facility Layer Gap | The standards do not unambiguously define which set of encoding rules to use. |
