Pathway Communications Unit --> Other ITS Objects:
local ITS information

Definitions

local ITS information (Information Flow): ITS information that is relevant to a particular location (e.g., a particular intersection) that is of interest to receivers near that location. This flow is a super-flow; it does not define specific content since it represents any information flow exchange using short range communications between physical objects defined in ARC-IT. This includes both broadcast communications to all receivers within range and unicast communications targeted for a specific receiver. This information flow represents any of those information flows and inherits the data content and attributes defined in the more detailed information flows.

Pathway Communications Unit (Source Physical Object): The 'Pathway Communications Unit' provides wireless communications between the pathway infrastructure (either indoor or outdoor) and nearby mobile devices; Communications with adjacent field equipment (including other PCUs) and back-office centers that monitor and control the PCU are also supported. The PCU provides basic radio communications supporting the lower layers of the OSI stack (TransNet and SubNet layers of the ARC-IT communications model). Importantly, it can also serve as a reference for mobile devices to determine their position more accurately (e.g., through triangulation or other means).

Other ITS Objects (Destination Physical Object): Representing other ITS Objects, 'Other ITS Objects' provides a source and destination for information exchange between ITS Objects.
