1.2.7.8: Provide Device Interface to Other Roadway Devices

This process shall provide the interface between roadway devices and other roadway devices (considered to be contained in the Other ITS Roadway Equipment terminator) for the exchange of data, status, and control. The Other ITS Roadway Equipment can be adjacent geographically, under control of a different jurisdiction, or part of a more complex hierarchy. The devices described by ITS processes that will send data and status to the Other ITS Roadway Equipment terminator (and receive control signals from the Other ITS Roadway Equipment terminator) include controllers (arterial or freeway), traffic sensors, roadway information systems (e.g. dynamic message signs or highway advisory radios), environmental systems, lane control systems, reversible lane systems, variable speed systems, roadway auto-treatment systems, barrier and safeguard systems, emissions or pollution systems, and work zone intrusion alert systems. This process supports autonomous traffic information dissemination without the need for direct control from a Manage Traffic function.

This process is associated with the ITS Roadway Equipment physical object.
