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.
Center	Center	This general physical object is used to model core capabilities that are common to any center.
Connected Vehicle Roadside Equipment	Field	'Connected Vehicle Roadside Equipment' (CV RSE) represents the Connected Vehicle roadside devices (i.e., Roadside Units (RSUs)) equipped with short range wireless (SRW) communications technology, as well as any other supporting equipment that leverage the RSU and are not described by other objects (e.g., a local roadside processor). CVRSE are used to send messages to, and receive messages from, nearby vehicles and personal devices equipped with compatible communications technology. 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.
Field	Field	This general physical object is used to model core capabilities that are common to any piece of field equipment.
Location and Time Data Source	ITS	The 'Location and Time Data Source' provides accurate position information. While a Global Positioning System (GPS) Receiver is the most common implementation, this physical object represents any technology that provides a position fix in three dimensions and time with sufficient accuracy.
Personal	Personal	The 'Personal' physical object is used to model core capabilities that are common to more than one physical object in the 'Personal' class. It provides the general executive, management, and utility functions that may be shared by different types of personal devices.
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 (including motorcycles), 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.

Field Time Management	'Field Time Management' provides foundational time keeping functionality that supports an accurate, synchronized time reference in ITS field equipment. It receives accurate time information from an external source and maintains a local time reference using an internal clock in between time synchronizations.	Field
Personal Location Determination	'Personal Location Determination' receives current location information and provides this information to other applications that use the location information to provide guidance and emergency notification services. It interfaces with and encapsulates positioning technology such as a GPS receiver that is embedded in the user's device.	Personal
RSE Position Correction Support	'RSE Position Correction Support' broadcasts differential positioning data to enable precise locations to be determined by passing vehicles, supporting Connected Vehicle applications that require highly accurate positioning. The differential positioning data may be calculated directly by a precisely located RSE that is operating as a reference station or received from an external reference station and relayed to passing vehicles.	Connected Vehicle Roadside Equipment
RSE Support Services	'RSE Support Services' provides foundational functions that support data collection, management, location reference, timing, and data distribution. It coordinates with Support subsystems to maintain necessary registrations with respect to location and scope. It maintains precise location and time information to support other services.

Location and time data is the basis for crash imminent safety and a host of other applications. Corruption of this flow could lead directly to a vehicle accident.	If this information is not available, crash imminent safety applications depending on this information will not function properly.
