Definitions

air quality information (Information Flow): Aggregated region-wide measured air quality data and possible pollution incident information.

Emissions Management Center (Source Physical Object): The 'Emissions Management Center' provides the capabilities for air quality managers to monitor and manage air quality. These capabilities include collecting emissions data from distributed emissions sensors (included in ITS Roadway Equipment) and directly from connected vehicles. The sensors monitor general air quality and also monitor the emissions of individual vehicles on the roadway. The measures are collected, processed, and used to support environmental monitoring applications.

Media (Destination Physical Object): 'Media' represents the information systems that provide traffic reports, travel conditions, and other transportation-related news services to the traveling public through radio, TV, and other media. Traffic and travel advisory information that are collected by ITS are provided to this object. It is also a source for traffic flow information, incident and special event information, and other events that may have implications for the transportation system.

This Triple has the following triple relationships:

None

Communication Solutions

(None-Data) - Secure Internet (ITS) (43)
(None-Data) - Apache Kafka (44)
(None-Data) - OMG DDS (44)
(None-Data) - OASIS MQTT (50)
(None-Data) - OASIS AMQP (61)

Solutions are sorted in ascending Gap Severity order. The Gap Severity is the parenthetical number at the end of the solution.

Selected Solution

(None-Data) - OASIS AMQP

Solution Description

This solution is used within Canada, the E.U. and the U.S.. It combines standards associated with (None-Data) with those for OASIS AMQP. The (None-Data) standards include an unspecified set of standards at the upper layers. The OASIS AMQP standards include lower-layer standards that support data distribution of specific types of data.

Note that some layers might have alternatives, in which case all of the gap icons associated with every alternative may be shown on the diagram, but the solution severity calculations (and resulting ordering of solutions) includes only the issues associated with the default (i.e., best, least severe) alternative.

Interoperability	Description
Regional	Interoperability throughout the geopolitical region is highly desirable, but if implemented differently in different transportation management jurisdictions, significant benefits will still accrue in each jurisdiction. Regardless, this Information Flow Triple should be implemented consistently within a transportation jurisdiction (i.e., the scope of a regional architecture).

Security

Information Flow Security
	Confidentiality	Integrity	Availability
Rating	Not Applicable	Moderate	Low
Basis	This flow does not contain any personal or confidential information, and the data contained is eventually intended for public consumption.	Information for general distribution should have at least some guarantee that it was correctly transmitted. If this information were incorrect, people could be exposed to higher levels of pollution than they would intend, which could be harmful to people with medical conditions such as asthma.	Not a key flow for any service package. If an application is developed that relies on this flow, may change to MODERATE.
