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.
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.
ITS Roadway Equipment Field 'ITS Roadway Equipment' represents the ITS equipment that is distributed on and along the roadway that monitors and controls traffic and monitors and manages the roadway. This physical object includes traffic detectors, environmental sensors, traffic signals, highway advisory radios, dynamic message signs, CCTV cameras and video image processing systems, grade crossing warning systems, and ramp metering systems. Lane management systems and barrier systems that control access to transportation infrastructure such as roadways, bridges and tunnels are also included. This object also provides environmental monitoring including sensors that measure road conditions, surface weather, and vehicle emissions. Work zone systems including work zone surveillance, traffic control, driver warning, and work crew safety systems are also included.
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.
Potential Obstacles Field 'Potential Obstacles' represents any object that possesses the potential of being sensed and struck and thus also possesses physical attributes. Potential Obstacles include roadside obstructions, debris, animals, infrastructure elements (barrels, cones, barriers, etc.) or any other element that is in a potential path of the vehicle. Note that roadside objects and pieces of equipment that can become obstacles in a vehicle's path can include materials, coatings, or labels (e.g., barcodes) that will improve the performance of the vehicle-based sensors that must detect and avoid these obstacles. See also 'Vulnerable Road Users' that more specifically represents the physical properties of shared users of the roadway that must also be detected.
Roadway Environment Field 'Roadway Environment' represents the physical condition and geometry of the road surface, markings, signs, and other objects on or near the road surface. It also represents the environmental conditions immediately surrounding the roadway. The roadway environment must be sensed and interpreted to support automated vehicle services. Surrounding conditions may include fog, ice, snow, rain, wind, etc. which will influence the way in which a vehicle can be safely operated on the roadway. The roadway environment must be monitored to enable corrective action and information dissemination regarding roadway conditions which may adversely affect travel. Infrastructure owner/operators can improve the roadway environment to improve the performance and accuracy of vehicle-based sensors that must sense and interpret this environment. Improvements could include changes in the shape, size, design, and materials used in signs, pavement markings, and other road features.
Traffic Management Center Center The 'Traffic Management Center' monitors and controls traffic and the road network. It represents centers that manage a broad range of transportation facilities including freeway systems, rural and suburban highway systems, and urban and suburban traffic control systems. It communicates with ITS Roadway Equipment and Connected Vehicle Roadside Equipment (RSE) to monitor and manage traffic flow and monitor the condition of the roadway, surrounding environmental conditions, and field equipment status. It manages traffic and transportation resources to support allied agencies in responding to, and recovering from, incidents ranging from minor traffic incidents through major disasters.
Traffic Operations Personnel Center 'Traffic Operations Personnel' represents the people that operate a traffic management center. These personnel interact with traffic control systems, traffic surveillance systems, incident management systems, work zone management systems, and travel demand management systems. They provide operator data and command inputs to direct system operations to varying degrees depending on the type of system and the deployment scenario.
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.
Vehicle Characteristics Vehicle 'Vehicle Characteristics' represents the external view of individual vehicles of any class from cars and light trucks up to large commercial vehicles and down to micromobility vehicles (MMVs). It includes vehicle physical characteristics such as height, width, length, weight, and other properties (e.g., magnetic properties, number of axles) of individual vehicles that can be sensed and measured or classified. This physical object represents the physical properties of vehicles that can be sensed by vehicle-based or infrastructure-based sensors to support vehicle automation and traffic sensor systems. The analog properties provided by this terminator represent the sensor inputs that are used to detect and assess vehicle(s) within the sensor's range to support safe AV operation and/or responsive and safe traffic management.
Vulnerable Road Users Personal 'Vulnerable Road Users' represents any roadway user not in a motorized vehicle capable of operating at the posted speed for the roadway in question, and also any roadway user in a vehicle not designed to encase (and thus protect) its occupants. This includes pedestrians, cyclists, wheelchair users, two-wheeled scooter micromobility users, as well as powered scooters and motorcycles. Note that this terminator represents the physical properties of vulnerable road users and their conveyance that may be sensed to support safe vehicle automation and traffic management in mixed mode applications where a variety of road users share the right-of-way. See also 'Pedestrian' and 'MMV User' Physical Objects that represent the human interface to these vulnerable road users.

A broad array of weather and road surface information may be collected. Weather conditions that may be measured include temperature, wind, humidity, precipitation, and visibility. Surface and sub-surface sensors can measure road surface temperature, moisture, icing, salinity, and other metrics. ITS Roadway Equipment
RSE Automated Vehicle Operations 'RSE Automated Vehicle Operations' includes the field elements that monitor and control access to and egress from automated lanes. It monitors and coordinates automated vehicle operations within the lanes. These lanes support vehicles operating in platoons with short headways. Connected Vehicle Roadside Equipment
RSE Environmental Monitoring 'RSE Environmental Monitoring' collects environmental situation (probe) data from passing vehicles that are equipped with short range communications capability. The collected data includes current environmental conditions as measured by on-board sensors (e.g., ambient temperature and precipitation measures), current status of vehicle systems that can be used to infer environmental conditions (e.g., status of lights, wipers, ABS, and traction control systems), and emissions measures reported by the vehicle. The functional object collects the provided data, aggregates and filters the data based on provided configuration parameters, and sends the collected information back to a center for processing and distribution. This functional object may also process the collected data locally and issue short-term road weather advisories for the road segment using short range communications. Connected Vehicle Roadside Equipment
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
TIC Traffic Control Dissemination 'TIC Traffic Control Dissemination' disseminates intersection status, lane control information, and other traffic control related information that is real-time or near real-time in nature and relevant to vehicles in a relatively local area on the road network.

It also provides an interface to other centers to allow monitoring and control of the barriers from other centers (e.g., public safety or emergency operations centers). Traffic Management Center
TMC Basic Surveillance 'TMC Basic Surveillance' remotely monitors and controls traffic sensor systems and surveillance (e.g., CCTV) equipment, and collects, processes and stores the collected traffic data. Current traffic information and other real-time transportation information is also collected from other centers. The collected information is provided to traffic operations personnel and made available to other centers. Traffic Management Center
TMC Environmental Monitoring 'TMC Environmental Monitoring' assimilates current and forecast road conditions and surface weather information using a combination of weather service provider information, information collected by other centers such as the Maintenance and Construction Management Center, data collected from environmental sensors deployed on and about the roadway, and information collected from connected vehicles. The collected environmental information is monitored and presented to the operator. This information can be used to issue general traveler advisories and support location specific warnings to drivers. Traffic Management 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 Control Automation 'Vehicle Control Automation' provides lateral and/or longitudinal control of a vehicle to allow 'hands off' and/or 'feet off' driving, automating the steering, accelerator, and brake control functions. It builds on the sensors included in 'Vehicle Safety Monitoring' and 'Vehicle Control Warning' and uses the information about the area surrounding the vehicle to safely control the vehicle. It covers the range of incremental control capabilities from driver assistance systems that take over steering or acceleration/deceleration in limited scenarios with direct monitoring by the driver to full automation where all aspects of driving are automated under all roadway and environmental conditions. Vehicle
Vehicle Control Warning 'Vehicle Control Warning' monitors areas around the vehicle and provides warnings to a driver so the driver can take action to recover and maintain safe control of the vehicle. It includes lateral warning systems that warn of lane departures and obstacles or vehicles to the sides of the vehicle and longitudinal warning systems that monitor areas in the vehicle path and provide warnings when headways are insufficient or obstacles are detected in front of or behind the vehicle. It includes on-board sensors, including radars and imaging systems, and the driver information system that provides the visual, audible, and/or haptic warnings to the driver. Vehicle
Vehicle Environmental Monitoring 'Vehicle Environmental Monitoring' collects data from on-board sensors and systems related to environmental conditions and sends the collected data to the infrastructure as the vehicle travels. The collected data is a byproduct of vehicle safety and convenience systems and includes ambient air temperature and precipitation measures and status of the wipers, lights, ABS, and traction control systems. Vehicle
Vehicle Platoon Operations 'Vehicle Platoon Operations' provides the capability for vehicles to operate in cooperative platoons with short fixed gaps and a designated lead vehicle. These capabilities are provided by systems on board the vehicle that coordinate with other vehicles and regulate acceleration and braking and provide higher-level functions that enable vehicles to join and depart from vehicle platoons.

This exchange also supports identification of non-equipped vehicles where an RSE is used for payment collection. This generic exchange can be implemented by any approach that compares vehicle detections with V2I communications by the RSE to identify vehicles that are not equipped or are otherwise unable to communicate with the RSE.
vehicle environmental data Data from vehicle safety and convenience systems that can be used to estimate environmental and infrastructure conditions, including measured air temperature, exterior light status, wiper status, sun sensor status, rain sensor status, traction control status, anti-lock brake status, vertical acceleration and other collected vehicle system status and sensor information. The collected data is reported along with the location, heading, and time that the data was collected. Both current data and snapshots of recent events (e.g., traction control or anti-lock brake system activations) may be reported.
vehicle location and motion Data describing the vehicle's location in three dimensions, heading, speed, acceleration, braking status, and size.
vehicle platoon coordination Coordination of control commands between leader and follower vehicles allowing vehicles to join, coordinate with, and separate from platoons of cooperative vehicles. This flow shares platoon size, location, and performance parameters (e.g., platoon speed and spacing) between platooned vehicles. It also coordinates maneuvers between platooned vehicles, including maneuvers as vehicles join and leave the platoon.
vehicle profile Information about a vehicle such as vehicle make and model, fuel type, engine type, size and weight, vehicle performance and level of control automation, average emissions, average fuel consumption, passenger occupancy, or other data that can be used to classify vehicle eligibility for access to specific lanes, road segments, or regions or participation in cooperative vehicle control applications.
vulnerable road user presence Detection of pedestrians, cyclists, and other vulnerable road users. This detection is based on physical characteristics of the user and their conveyance, which may be enhanced by design and materials that facilitate sensor-based detection and tracking of vulnerable road users.

ITS Roadway Equipment Traffic Management Center barrier system status Moderate High Moderate
Related to the control flow, however the data is directly observable and generally widely known. Difficult to justify obfuscation. Status of barrier systems has direct human-safety related impact, that if performed incorrectly could lead to catastrophic incidents. These systems need to operated when demanded or mobility will be restricted. However, manual processes should always be in place to compensate for a loss in connectivity, and to provide a secondary check for safety purposes anyway.

Other Vehicles Vehicle vehicle environmental data Low Moderate Moderate
Little abusive potential for capturing the information in this flow as designed. Could be moderate if this contains PII related information, but considered for now to not include any PII; DISC: WYO believes Vehicle to Center versions of this flow to be MODERATE as center penetrations could more easily garner aggregate user data that might be used for mischief. This could be used for safety applications, and in areas of severe weather a corrupted field could have significant consequences; however, any vehicle will use other inputs before triggering automatic safety facilities, so MODERATE should be sufficient. DISC: WYO believes this to be HIGH. This data is required for the system to operate properly. If this data is not available, the system cannot give accurate warning information.
Other Vehicles Vehicle vehicle location and motion Not Applicable High Moderate
This data is intentionally transmitted to everyone via a broadcast. Much of its information content can also be determined via other visual indicators BSM info needs to be accurate and should not be tampered with BSM must be broadcast regularly to make data available for other vehicle OBEs, but availability cannot be guaranteed over a wireless medium
Other Vehicles Vehicle vehicle platoon coordination Low High Moderate
Includes the identity of the lead vehicle but no PII. Intended for vehicles to coordinate tightly, and with no previous relationship so likely open to other vehicles monitoring. Platooning coordination data must be correct or potentially severe consequences can result, particularly if data relevant to high speed operations is corrupted. Platooning will not fully function without this flow; the worst case is that vehicles drop from the platoon however; lack of this flow is unlikely to generate a severe incident on its own.

Control flows, even for seemingly innocent devices, should be kept confidential to minimize attack vectors. While an individual installation may not be particularly impacted by a cyberattack of its sensor network, another installation might be severely impacted, and different installations are likely to use similar methods, so compromising one leads to compromising all. Control flows, even for seemingly innocent devices, should have MODERATE integrity at minimum, just to guarantee that intended control messages are received. Incorrect, corrupted, intercepted and modified control messages can or will result in target field devices not behaving according to operator intent. The severity of this depends on the type of device, which is why some devices are set MODERATE and some HIGH. Control flow availability is related to the criticality of being able to remotely control the device. For most devices, this is MODERATE. For purely passive devices with no incident relationship, this will be LOW. All devices should have default modes that enable them to operate without backhaul connectivity, so no device warrants a HIGH.

Backoffice operations flows should have minimal protection from casual viewing, as otherwise imposters could gain illicit control or information that should not be generally available. Information presented to backoffice system operators must be consistent or the operator may perform actions that are not appropriate to the real situation.

This information is all presented to the vehicle operator. Encrypting this information may make it harder to reverse engineer vehicle systems, and may defeat criminal tracking tools when the vehicle has already been compromised. Unless those scenarios are of concern to the operator or manufacturer, this can safely be set LOW. Any information presented to the operator of a vehicle should be both accurate and timely. By definition this includes safety information, but given that the driver has other means of learning about most threats, it seems difficult to justify HIGH. If HIGH is warranted, it should apply to both availability and integrity. Any information presented to the operator of a vehicle should be both accurate and timely.

Vehicle Basic Vehicle vehicle control Moderate High High
Internal vehicle flow that if reverse engineered could enable third party vehicle control. Largely a competitive question, could be set LOW if manufacturer and operator are not concerned with this type of compromise. Includes vehicle control commands, which must be timely and accurate to support safe vehicle operation. Includes vehicle control commands, which must be timely and accurate to support safe vehicle operation.
Vehicle Connected Vehicle Roadside Equipment automated vehicle control status Moderate Moderate Moderate
Automated vehicle operating conditions could imply PII, and as they are internal measures should be provided only to intended recipients. Automated vehicle operating conditions, if reported incorrectly, could result in warnings or operations responses that are inappropriate. Other mechanisms for determining this information are unlikely, but given compettive concerns, applications will have to be designed to work without this data.
Vehicle Connected Vehicle Roadside Equipment vehicle environmental data Low Moderate Low
Little abusive potential for capturing the information in this flow as designed. Could be moderate if this contains PII related information, but considered for now to not include any PII; DISC: WYO believes Vehicle to Center versions of this flow to be MODERATE as center penetrations could more easily garner aggregate user data that might be used for mischief. Some minimal guarantee of data integrity is necessary for all C-ITS flows. DISC THEA believes this to be LOW: Data should be accurate and not tampered with but should be able to cope with some bad data in traffic/environmental condition monitoring; aggregate data; can also receive data from ITS RE; DISC: WYO believes this to be MODERATE data should be timely and readily available, but limited adverse effect; aggregate data; can also receive data from ITS RE; DISC: WYO believes this to be MODERATE
Vehicle Connected Vehicle Roadside Equipment vehicle location and motion Not Applicable High Moderate
This data is intentionally transmitted to everyone via a broadcast. Much of its information content can also be determined via other visual indicators Incorrect information could lead to the system not operating properly. If the system does not properly know where the vehicle is, it cannot make an accurate decision about whether there is going to be a pedestrian in the crosswalk that the vehicle is approaching. This can have a safety impact.; DISC: NYC believes this to be MODERATE This data is required for the system to operate properly. If this data is not available, the system cannot give accurate warning information.
Vehicle Connected Vehicle Roadside Equipment vehicle platoon coordination Low High Moderate
Includes the identity of the lead vehicle but no PII. Intended for vehicles to coordinate tightly, and with no previous relationship so likely open to other vehicles monitoring. Platooning coordination data must be correct or potentially severe consequences can result, particularly if data relevant to high speed operations is corrupted. Platooning will not fully function without this flow; the worst case is that vehicles drop from the platoon however; lack of this flow is unlikely to generate a severe incident on its own.
Vehicle Connected Vehicle Roadside Equipment vehicle profile Low Moderate Moderate
Includes no PII and probably includes information that could be observed, so no need for obfuscation. As this information will be used to determine the vehicle's ability to access services or be charged usage fees, it must be correct and not easily forgeable. This flow enables various services; if the flow is not available the vehicle may not be able to use those services, and also may be charged incorrectly.
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 Other Vehicles vehicle environmental data Low Moderate Moderate
Little abusive potential for capturing the information in this flow as designed. Could be moderate if this contains PII related information, but considered for now to not include any PII; DISC: WYO believes Vehicle to Center versions of this flow to be MODERATE as center penetrations could more easily garner aggregate user data that might be used for mischief. This could be used for safety applications, and in areas of severe weather a corrupted field could have significant consequences; however, any vehicle will use other inputs before triggering automatic safety facilities, so MODERATE should be sufficient. DISC: WYO believes this to be HIGH. This data is required for the system to operate properly. If this data is not available, the system cannot give accurate warning information.
Vehicle Other Vehicles vehicle location and motion Not Applicable High Moderate
This data is intentionally transmitted to everyone via a broadcast. Much of its information content can also be determined via other visual indicators BSM info needs to be accurate and should not be tampered with BSM must be broadcast regularly to make data available for other vehicle OBEs, but availability cannot be guaranteed over a wireless medium
Vehicle Other Vehicles vehicle platoon coordination Low High Moderate
Includes the identity of the lead vehicle but no PII. Intended for vehicles to coordinate tightly, and with no previous relationship so likely open to other vehicles monitoring.
