Link Type: Human Interface

Vehicle OBE --> Driver:
driver updates

Definitions

driver updates (Information Flow): Information provided to the driver including visual displays, audible information and warnings, and haptic feedback. The updates inform the driver about current conditions, potential hazards, and the current status of vehicle on-board equipment.

Vehicle OBE (Source Physical Object): The Vehicle On-Board Equipment (OBE) provides the vehicle-based processing, storage, and communications functions necessary to support connected vehicle operations. The radio(s) supporting V2V and V2I communications are a key component of the Vehicle OBE. This communication platform is augmented with processing and data storage capability that supports the connected vehicle applications.

In CVRIA, the Vehicle OBE includes the functions and interfaces that support connected vehicle applications for passenger cars, trucks, and motorcycles. Many of these applications (e.g., V2V Safety applications) apply to all vehicle types including personal vehicles, commercial vehicles, emergency vehicles, transit vehicles, and maintenance vehicles. From this perspective, the Vehicle OBE includes the common interfaces and functions that apply to all motorized vehicles.

Driver (Destination Physical Object): The 'Driver' represents the person that operates a vehicle on the roadway. Included are operators of private, transit, commercial, and emergency vehicles where the interactions are not particular to the type of vehicle (e.g., interactions supporting vehicle safety applications). The Driver originates driver requests and receives driver information that reflects the interactions which might be useful to all drivers, regardless of vehicle classification. Information and interactions which are unique to drivers of a specific vehicle type (e.g., fleet interactions with transit, commercial, or emergency vehicle drivers) are covered by separate objects.

Security

This information flow triple is in the following applications with the following security levels.

Information Flow Security
Application Confidentiality Integrity Availability
Basis Basis Basis
Incident Scene Work Zone Alerts for Drivers and Workers Low Moderate Moderate
This data is informing the driver about the existence of an incident work zone. It should not contain anything sensitive, and does not matter if another person can observe it. This is the information that is presented to the driver. If they receive incorrect information, they may act in an unsafe manner. However, there are other indicators that would alert them to any hazards, such as flashing lights, or a flaming car in the middle of a road. If this information is not made available to the driver, then the system has not operated correctly.
Pedestrian in Signalized Crosswalk Warning Low Moderate Moderate
This data is informing the driver about the safety of the intersections. It should not contain anything sensitive, and does not matter if another person can observe it. This is the information that is presented to the driver. If they receive incorrect information, they may act in an unsafe manner. However, there are other indicators that would alert them to any hazards, such as an oncoming vehicle or crossing safety lights. If this information is not made available to the driver, then the system has not operated correctly.
