Link Type: Human Interface

Commercial Vehicle Check Equipment --> Commercial Vehicle Driver:
CVO pass/pull-in message

Definitions

CVO pass/pull-in message (Information Flow): This flow represents the visual or auditory interface with ITS equipment containing a message sent to commercial vehicle driver indicating whether to bypass or requesting pull in to inspection/verification stop along with inspection results (e. g., LED indicator on transponder or variable message sign).

Commercial Vehicle Check Equipment (Source 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.

Commercial Vehicle Driver (Destination Physical Object): The 'Commercial Vehicle Driver' represents the people that operate vehicles transporting goods, including both long haul trucks and local pick-up and delivery vans. This physical object is complementary to the Driver physical object in that it represents those interactions which are unique to Commercial Vehicle Operations. Information flowing from the Commercial Vehicle Driver includes those system inputs specific to Commercial Vehicle Operations.

Interoperability Description
Not Applicable Interoperability ratings don't apply per se to some types of interfaces like human interfaces. These interfaces may still benefit from associated standards (e.g., ergonomic and human factors standards for human interfaces), but the primary motive for these standards is not interoperability.

Rating Not Applicable High High
Basis This interface is also directly observable. Data should be correct as it relates to CVO, however there is generally another mechanism to double-check this data, which is why it is MODERATE and not HIGH. If roadside mechanisms are not existent, then this would be HIGH.
