Connected Vehicle Roadside Equipment --> Traffic Management Center:
cooperative cruise control application status
Definitions
cooperative cruise control application status (Information Flow): Current operational status of the infrastructure enhanced cooperative adaptive cruise control application. The flow includes the status of the RSEs, associated field equipment, and CACC-equipped vehicle strings using the facility.
Connected Vehicle Roadside Equipment (Source Physical Object): 'Connected Vehicle Roadside Equipment' (CV RSE) represents the Connected Vehicle roadside devices that are used to send messages to, and receive messages from, nearby vehicles using Dedicated Short Range Communications (DSRC) or other alternative wireless communications technologies. Communications with adjacent field equipment and back office centers that monitor and control the RSE are also supported. This device operates from a fixed position and may be permanently deployed or a portable device that is located temporarily in the vicinity of a traffic incident, road construction, or a special event. It includes a processor, data storage, and communications capabilities that support secure communications with passing vehicles, other field equipment, and centers.
Traffic Management Center (Destination Physical Object): The 'Traffic Management Center' monitors and controls traffic and the road network. It represents centers that manage a broad range of transportation facilities including freeway systems, rural and suburban highway systems, and urban and suburban traffic control systems. It communicates with ITS Roadway Equipment and Connected Vehicle Roadside Equipment (RSE) to monitor and manage traffic flow and monitor the condition of the roadway, surrounding environmental conditions, and field equipment status. It manages traffic and transportation resources to support allied agencies in responding to, and recovering from, incidents ranging from minor traffic incidents through major disasters.

Interoperability | Description |
---|---|
Local | In cases where an interface is normally encapsulated by a single stakeholder, interoperability is still desirable, but the motive is vendor independence and the efficiencies and choices that an open standards-based interface provides. |

Basis | This information could be of interest to a malicious individual who is attempting to determine the best way to accomplish a crime. As such it would be best to not make it easily accessible. May be LOW in some cases. | If this is compromised, it could send unnecessary maintenance workers, or worse create a safety problem for CACC participants. Given that the impact of the latter scenario is very high and includes human safety, set to HIGH. | There will be fallback means for operating CACC without the RSE's input, however if an RSE were operational but its backhaul were compromised while it had out of date parameters, this scenario could be leveraged to disrupt CACC, thus MODERATE. |
