Physical Object Class Description
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.
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.
Other Vehicles Vehicle 'Other Vehicle OBEs' represents other connected vehicles that are communicating with the host vehicle. This includes all connected motorized vehicles including passenger cars, trucks, and motorcycles and specialty vehicles (e.g., maintenance vehicles, transit vehicles) that also include the basic 'Vehicle OBE' functionality that supports V2V communications. This object provides a source and destination for information transfers between connected vehicles. The host vehicle on-board equipment, represented by the Vehicle OBE physical object, sends information to, and receives information from the Other Vehicle OBEs to model all connected vehicle V2V communications in ARC-IT.
Transportation Information Center Center The 'Transportation Information Center' collects, processes, stores, and disseminates transportation information to system operators and the traveling public. The physical object can play several different roles in an integrated ITS. In one role, the TIC provides a data collection, fusing, and repackaging function, collecting information from transportation system operators and redistributing this information to other system operators in the region and other TICs. In this information redistribution role, the TIC provides a bridge between the various transportation systems that produce the information and the other TICs and their subscribers that use the information. The second role of a TIC is focused on delivery of traveler information to subscribers and the public at large. Information provided includes basic advisories, traffic and road conditions, transit schedule information, yellow pages information, ride matching information, and parking information. The TIC is commonly implemented as a website or a web-based application service, but it represents any traveler information distribution service.
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.

Includes Functional Objects:

Functional Object Description Physical Object
RSE Traffic Monitoring 'RSE Traffic Monitoring' monitors the basic safety messages that are shared between connected vehicles and distills this data into traffic flow measures that can be used to manage the network in combination with or in lieu of traffic data collected by infrastructure-based sensors. As connected vehicle penetration rates increase, the measures provided by this application can expand beyond vehicle speeds that are directly reported by vehicles to include estimated volume, occupancy, and other measures. This object also supports incident detection by monitoring for changes in speed and vehicle control events that indicate a potential incident. Connected Vehicle Roadside Equipment
RSE Traveler Information Communications 'RSE Traveler Information Communications' includes field elements that distribute information to vehicles for in-vehicle display. The information may be provided by a center (e.g., variable information on traffic and road conditions in the vicinity of the field equipment) or it may be determined and output locally (e.g., static sign information and signal phase and timing information). This includes the interface to the center or field equipment that controls the information distribution and the short range communications equipment that provides information to passing vehicles. Connected Vehicle Roadside Equipment
TIC Connected Vehicle Traveler Info Distribution In support of connected vehicle applications, 'TIC Connected Vehicle Traveler Info Distribution' disseminates traveler information including traffic and road conditions, incident information, maintenance and construction information, event information, transit information, parking information, and weather information. Location-specific or situation-relevant traveler information is sent to short range communications transceivers at the roadside. Transportation Information Center
TIC Situation Data Management 'TIC Situation Data Management' manages connected vehicle situation data collection, quality controls, filtering, aggregation, and storage. Through this process, raw data reported by connected vehicles are transformed into information products that can be accessed and used to support transportation operations and traveler information. The distribution of the connected vehicle-derived information products is handled by other functional objects. Transportation Information Center
TIC Traveler Information Broadcast 'TIC Traveler Information Broadcast' disseminates traveler information including traffic and road conditions, incident information, maintenance and construction information, event information, transit information, parking information, and weather information. The same information is broadcast to all equipped traveler interface systems and vehicles. Transportation Information Center
Vehicle Basic Safety Communication 'Vehicle Basic Safety Communication' exchanges current vehicle location and motion information with other vehicles in the vicinity, uses that information to calculate vehicle paths, and warns the driver when the potential for an impending collision is detected. If available, map data is used to filter and interpret the relative location and motion of vehicles in the vicinity. Information from on-board sensors (e.g., radars and image processing) are also used, if available, in combination with the V2V communications to detect non-equipped vehicles and corroborate connected vehicle data. Vehicle location and motion broadcasts are also received by the infrastructure and used by the infrastructure to support a wide range of roadside safety and mobility applications. This object represents a broad range of implementations ranging from basic Vehicle Awareness Devices that only broadcast vehicle location and motion and provide no driver warnings to advanced integrated safety systems that may, in addition to warning the driver, provide collision warning information to support automated control functions that can support control intervention. Vehicle
Vehicle Eco-Driving Assist 'Vehicle Eco-Driving Assist' provides customized real-time driving advice to drivers, allowing them to adjust behaviors to save fuel and reduce emissions. This advice includes recommended driving speeds, optimal acceleration and deceleration profiles based on prevailing traffic conditions, and local interactions with nearby vehicles, i.e., processing Basic Safety Messages (BSMs) to determine position and speed of vehicles that are between the host vehicle and the intersection. When approaching and departing signalized intersections, it uses intersection geometry information, the relative position and speed of vehicles ahead of it, and signal phase movement information to provide speed advice to the driver so that the driver can adapt the vehicle's speed to pass the next traffic signal on green, decelerate to a stop in the most eco-friendly manner, or manage acceleration as the vehicle departs from a signalized intersection. It also provides feedback to drivers on their driving behavior to encourage them to drive in a more environmentally efficient manner. It may also support vehicle-assisted strategies, where the vehicle automatically implements the eco-driving strategy (e.g., changes gears, switches power sources, or reduces its speed in an eco-friendly manner as the vehicle approaches a traffic signal or queue). Vehicle
Vehicle Traveler Information Reception 'Vehicle Traveler Information Reception' receives advisories, vehicle signage data, and other driver information of use to all types of vehicles and drivers and presents this information to the driver using in-vehicle equipment. Information presented may include fixed sign information, traffic control device status (e.g., signal phase and timing data), advisory and detour information, warnings of adverse road and weather conditions, travel times, and other driver information. Vehicle

Connected Vehicle Roadside Equipment Transportation Information Center traffic situation data Moderate Moderate Moderate
Aggregated messages may have more privacy implications than individual ones, especially if an attacker can attack more than one RSE-to-TMC connection at once. This information is used to help with incident detection. It should be verified to ensure that it is not incorrectly influencing this.THEA: only limited adverse effect if raw/processed connected vehicle data is bad/compromised; could be LOW for ISIG This information is used as supplemental information. It should operate correctly if not every single message is received.
Connected Vehicle Roadside Equipment Transportation Information Center traveler information application status Moderate Moderate Low
This information could be of interest to a malicious individual who is attempting to determine the best way to accomplish a crime. As such it would be best to not make it easily accessible. If this is compromised, it could send unnecessary maintenance workers, or cause the appearance of excessive traffic violations, leading to further unnecessary investigation. A delay in reporting this may cause a delay in necessary maintenance, but (a) this is not time-critical and (b) there are other channels for reporting malfunctioning. Additionally, there is a message received notification, which means that RSE can ensure that all intersection safety issues are delivered.
Connected Vehicle Roadside Equipment Vehicle local traveler information Not Applicable Moderate Low
This data is intentionally transmitted to everyone via a broadcast. It can also be determined via other visual indicators. Some minimal guarantee of data integrity is necessary for all C-ITS flows. Flaws in this information will have a minimal effect on systems receiving it. All of the information can be verified through other means, and in a worst case scenario will only cause slightly increased traffic in the general proximity of the RSE. DISC: Original V2I analysis classified this as LOW. All of the information provided through this flow will be available from other sources and no systems will directly rely upon it.
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.
