Includes Physical Objects:

Physical Object Class Description
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 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.
Data Distribution System Support The 'Data Distribution System' collects, processes, and distributes ITS data, connecting data producers with data consumers and facilitating data exchange.
Data Distribution System Operator Support The 'Data Distribution System Operator' represents the person or people that monitor and manage the data services provided by the Data Distribution System (DDS). These personnel manage and monitor the systems that support the publish/subscribe services of the DDS.
Other Data Distribution Systems Support Representing another Data Distribution System, 'Other Data Distribution Systems' is intended to provide a source and destination for information exchange between peer (e.g. inter-regional) data distribution systems. It supports modeling of projects or regions that include multiple interconnected data distribution systems that together manage data distribution in the connected vehicle environment.
Personal Information Device Personal The 'Personal Information Device' provides the capability for travelers to receive formatted traveler information wherever they are. Capabilities include traveler information, trip planning, and route guidance. Frequently a smart phone, the Personal Information Device provides travelers with the capability to receive route planning and other personally focused transportation services from the infrastructure in the field, at home, at work, or while en-route. Personal Information Devices may operate independently or may be linked with connected vehicle on-board equipment.
Vehicle OBE Vehicle The Vehicle On-Board Equipment (OBE) provides the vehicle-based sensory, processing, storage, and communications functions that support efficient, safe, and convenient travel. The Vehicle OBE includes general capabilities that apply to passenger cars, trucks, and motorcycles. 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 OBE 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 OBE. Both one-way and two-way communications options support a spectrum of information services from basic broadcast to advanced personalized information services. Route guidance capabilities assist in formulation of an optimal route and step by step guidance along the travel route. 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.

Query flows imply the interests of the source. Observation of this information betrays the privacy of the requestor. Depending on the type of requestor and type of information requested, this could be MODERATE. Query flows create long term relationships between source and DDS, and dictate what information the source receives. Corruption of this flow could have a significant impact on data reception; however, re-query should be a fairly simply process, justifying MODERATE and not HIGH. Query flows need some level of availability; if the flow is not satisfied the user may be become frustrated and seek a solution other than DDS. Thus MODERATE.
