Roadside Equipment --> Commercial Vehicle Check Equipment:
electronic lock data


electronic lock data (Information Flow): Notification to roadside (via transponder) of the presence and status of electronic cargo locks.

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.

Commercial Vehicle Check Equipment (Destination Physical Object): 'Commercial Vehicle Check Equipment' supports automated vehicle identification at mainline speeds for credential checking, roadside safety inspections, and weigh-in-motion using two-way data exchange. These capabilities include providing warnings to the commercial vehicle drivers, their fleet managers, and proper authorities of any safety problems that have been identified, accessing and examining historical safety data, and automatically deciding whether to allow the vehicle to pass or require it to stop with operator manual override. Commercial Vehicle Check Equipment also provides supplemental inspection services such as expedited brake inspections, the use of operator hand-held devices, mobile screening sites, on-board safety database access, and the enrollment of vehicles and carriers in the electronic clearance program.

This is a retransmission of low confidential data. No matter what the lock state is, there is no way to guarantee that exactly the right contents were put in the container before the lock was locked. Therefore, unless there is a HIGH-integrity process for inspecting the contents of each container, there is no value in providing HIGH integrity data about the state of the lock. This suggests that a MEDIUM integrity information flow is sufficient for the correct operation of this application. Note however that if a HIGH-integrity process is available for inspecting the contents of a particular container, then having HIGH integrity on this information flow might be valuable as it might allow the container to be processed more rapidly at the border crossing than would be the case for a MEDIUM-integrity information flow. So individual participants may choose to invest in a HIGH-integrity system, but the baseline requirement is MEDIUM integrity. If this data is missing, the system cannot make a decision about how to handle that vehicle. However, there are multiple chances for this data to be transmitted and received. Additionally, if the vehicle is not pre-approved it will be handled by border security.
