Roadside Equipment --> Freight Equipment:
container seal interrogation


container seal interrogation (Information Flow): Customs inspection of the electronic seal on a container to verify the container has not been opened or tampered with; requires proper authentication.

Roadside Equipment (Source Physical Object): 'Roadside Equipment' (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.

Freight Equipment (Destination Physical Object): 'Freight Equipment' represents a freight container, intermodal chassis, or trailer and provides sensory, processing, storage, and communications functions necessary to support safe, secure and efficient freight operations. It provides equipment safety data and status and can alert the appropriate systems of an incident, breach, or tamper event. It also provides accurate position information to support in-transit visibility of freight equipment.

The presence of electronic locks will most likely be observable by looking at the cargo doors and the other information is not sensitive in nature. The container seal status returned after this interrogation will not have a HIGH integrity, as such is interrogation does not require a HIGH integrity. If the integrity of the container seal status is somehow possible to raise to a HIGH, then this could also have a HIGH integrity. If this interrogation is not received, the system will not broadcast its Container Seal Status. However, there are multiple chances for this data to be transmitted and received. Additionally, if this information is never received the vehicle will be handled in the same way that it was prior to the implementation of this system.
