Field --> Personnel Device:
asset ID

Definitions

asset ID (Information Flow): A unique identification number and optional additional information. This flow represents the output of an RFID tag that is used for identification and tracking of assets, including both passive and active RFID tag technology options. For active tags, additional stored information that conveys additional information about the asset (e.g., lot number, production date, service data) may be provided along with the unique ID.

Field (Source Physical Object): This general physical object is used to model core capabilities that are common to any piece of field equipment.

Personnel Device (Destination Physical Object): 'Personnel Device' represents devices used by emergency personnel or maintenance and construction personnel in the field. In the case of emergency personnel, the devices would include body cameras or smartphones (and their peripherals) that can be used by emergency personnel to provide images or video as well as send or receive data regarding the incident. The devices could also be used for incident scene safety messages to the personnel. In the case of maintenance and construction field personnel, the devices could be cellular phones or specialized safety devices that would be used for work zone safety messages to the personnel.

Communication Solutions

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

Selected Solution

Proprietary Data - Proprietary Comm

Solution Description

This solution is used within Australia, Canada, the E.U. and the U.S.. It combines standards associated with Proprietary Data with those for Proprietary Comm. The Proprietary Data standards include upper-layer technologies that do not necessarily follow standards. The Proprietary Comm standards include lower-layer technologies that do not necessarily follow standards.

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 Low Moderate Moderate
Basis Unlikely that the ID of a particular asset, or even a group of assets would be useful to an attacker. Slight possibility, which is why Low vs. N/A. Infrastructure information should be correct or maintenance assets may be inappropriately assigned, located or otherwise referenced. Without this flow, asset location based safety applications may not function properly. The availability rating should mirror the importance of that service to the deployer. Generally if an operator goes to the trouble to track assets in the field this way, they consider this important and so the flow should be satisfied. Note that if an operator has multiple methods for tracking assets in the field, one instance of this flow could probably be reduced to LOW with minimal effect on service performance.
