Includes Physical Objects:

Physical Object Class Description
Basic Vehicle Vehicle 'Basic Vehicle' represents a complete operating vehicle. It includes the vehicle platform that interfaces with and hosts ITS electronics and all of the driver convenience and entertainment systems, and other non-ITS electronics on-board the vehicle. Interfaces represent both internal on-board interfaces between ITS equipment and other vehicle systems and other passive and active external interfaces or views of the vehicle that support vehicle/traffic monitoring and management. External interfaces may also represent equipment that is carried into the vehicle (e.g., a smartphone that is brought into the vehicle). Internal interfaces are often implemented through a vehicle databus, which is also included in this object. Note that 'Vehicle' represents the general functions and interfaces that are associated with personal automobiles as well as commercial vehicles, emergency vehicles, transit vehicles, and other specialized vehicles.
Driver Vehicle 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.
Enforcement Center Center The 'Enforcement Center' represents the systems that receive reports of violations detected by various ITS facilities including individual vehicle emissions, lane violations, toll violations, CVO violations, etc.
Service Monitor System Support The 'Service Monitor System' represents one or more center-based systems that provide monitoring, management and control services necessary to other applications and/or devices operating within the Connected Vehicle Environment. These support services enable other applications to provide transportation services.
Vehicle Vehicle This 'Vehicle' physical object is used to model core capabilities that are common to more than one type of Vehicle. It provides the vehicle-based general sensory, processing, storage, and communications functions that support efficient, safe, and convenient travel. Many of these capabilities (e.g., see the Vehicle Safety service packages) apply to all vehicle types including personal vehicles, commercial vehicles, emergency vehicles, transit vehicles, and maintenance vehicles. From this perspective, the Vehicle includes the common interfaces and functions that apply to all motorized vehicles. The radio(s) supporting V2V and V2I communications are a key component of the Vehicle. Both one-way and two-way communications options support a spectrum of information services from basic broadcast to advanced personalized information services. Advanced sensors, processors, enhanced driver interfaces, and actuators complement the driver information services so that, in addition to making informed mode and route selections, the driver travels these routes in a safer and more consistent manner. This physical object supports all six levels of driving automation as defined in SAE J3016. Initial collision avoidance functions provide 'vigilant co-pilot' driver warning capabilities. More advanced functions assume limited control of the vehicle to maintain lane position and safe headways. In the most advanced implementations, this Physical Object supports full automation of all aspects of the driving task, aided by communications with other vehicles in the vicinity and in coordination with supporting infrastructure subsystems.
Vehicle Service Center Center 'Vehicle Service Center' represents vehicle service centers that collect vehicle diagnostic information from vehicles and provide service options for drivers of these vehicles. The physical object also includes centers operated by vehicle manufacturers that can coordinate with connected vehicles to obtain vehicle operating data and provide software or data updates to connected vehicles that they have manufactured.

Includes Functional Objects:

Functional Object Description Physical Object
SM Device Management 'SM Device Management' provides the functions necessary to manage devices, including network management, operational status monitoring, and application performance monitoring. Service Monitor System
Vehicle System Executive 'Vehicle System Executive' provides the operating system kernel and executive functions that manage the software configuration and operation and support computer resource management, security, and software installation and upgrade. Vehicle
Vehicle System Monitoring and Diagnostics 'Vehicle System Monitoring and Diagnostics' includes on-board sensors and integrated self test software that monitors the condition of each of the vehicle systems and diagnostics that can be used to support vehicle maintenance. The status of the vehicle and ancillary equipment and diagnostic information is provided to the driver and service center. Vehicle

In order to participate in this service package, each information flow triple should meet or exceed the following security levels.

Information Flow Security
Source Destination Information Flow Confidentiality Integrity Availability
Basis Basis Basis
Basic Vehicle Vehicle host vehicle status Low Moderate High
Unlikely that this includes any information that could be used against the originator. This can be MODERATE or HIGH, depending on the application: This is used later on to determine whether a vehicle is likely going to violate a red light or infringe a work zone. This needs to be correct in order for the application to work correctly. Since this monitors the health and safety of the vehicle and that information is eventually reported to the driver, it should be available at all times as it directly affects vehicle and operator safety.
Driver Vehicle driver input Moderate High High
Data included in this flow may include origin and destination information, which should be protected from other's viewing as it may compromise the driver's privacy. Commands from from the driver to the vehicle must be correct or the vehicle may behave in an unpredictable and possibly unsafe manner Commands must always be able to be given or the driver has no control.
Driver Vehicle request for service Moderate High High
This request implies a declaration of intent, which if observed could provide leverage over the driver. Commands from from the driver to the vehicle must be correct or the vehicle may behave in an unpredictable and possibly unsafe manner Commands must always be able to be given or the driver has no control.
Enforcement Center Vehicle service request Moderate Moderate Moderate
Vehicle-specific and possibly PII. Could inconvenience the vehicle owner/operator if this flow is incorrect, manipulated or unavailable. Could inconvenience the vehicle owner/operator if this flow is incorrect, manipulated or unavailable.
Service Monitor System Vehicle Service Center OBE fault data Moderate Moderate Moderate
Device status information should not be viewable by third parties, as those with criminal intent may use this information toward their own ends. If incorrect or changed, could lead to inappropriate maintenance activity, which has a significant cost in itself and contributes negatively to system operational status. Scope is small, but impact significant if this occurs with many instances. A delay in reporting this may cause a delay in necessary maintenance. Considered higher availability requirement than the source flow (RSE status) because this information aggregates many instances of the source.
Vehicle Driver driver updates Not Applicable Moderate Moderate
This data is informing the driver about the safety of a nearby area. 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.
Vehicle Enforcement Center service record Moderate Moderate Moderate
Vehicle-specific and possibly PII. Could inconvenience the vehicle owner/operator if this flow is incorrect, manipulated or unavailable. Could inconvenience the vehicle owner/operator if this flow is incorrect, manipulated or unavailable.
Vehicle Service Monitor System OBE status Moderate Moderate Low
Will include some sort of identifier for the OBE, which could be used in combination with the status and configuration data as a means of identifying the type of vehicle, or in areas of low penetration the actual vehicle. Since this is used to monitor the health of the OBE, any corruption or modification of this information could lead to unnecessary maintenance activity, or delay necessary such activity. Impact will be limited to the OBEs who's flows were so affected. Unlikely that this needs to be reported often.
Vehicle Vehicle Service Center vehicle diagnostic data Moderate High Moderate
Vehicle OBE control, configuration and software/firmware update should all be protected from view. A hostile third party could use this information to reverse engineer control/configuration/update processes, and use that information in an attack across a broad swatch of vehicles, which would have severe effects to the connected vehicle environment. Vehicle device control, configuration and update need to be correct or the Vehicle OBE may be misconfigured, which for some applications could have severe safety impacts. Without the ability to locally diagnose, operate, update and configure the Vehicle OBE, the OBE is effectively out of control and would have to be taken out of service. Marked MODERATE and not HIGH however because a vehicle system is presumed to be able to operate without a connection to a backoffice service. For specific instances where this flow is used as part of a local, in-person configuration or maintenance service, would be HIGH.

Vehicle Service Center Vehicle vehicle software install/upgrade Low High Moderate
Equipment software could be sensitive, however this flow is local, meaning the Field Support Equipment is proximate to the TSE. Thus the risk of interception should be low. There may also be constraints on this flow that require this information to be transmitted in the clear. If it includes any authentication data however, this should be MODERATE. Software updates to the Vehicle OBE must be authenticated as having come from a source entitled to provide that software, or roadway equipment may be comprimised. Similarly, such software must be guaranteed to being the intent of the originator; not manipulated midstream or corrupted, or the OBE may be mis-configured or compromised. Without the ability to locally diagnose, operate, update and configure the Vehicle OBE, the OBE is effectively out of control and would have to be taken out of service. Marked MODERATE and not HIGH however because a vehicle system is presumed to be able to operate without a connection to a backoffice service.
