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.
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 (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.
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, occupants, emissions) 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.

Includes Functional Objects:

Functional Object Description Physical Object
Roadway Basic Surveillance 'Roadway Basic Surveillance' monitors traffic conditions using fixed equipment such as loop detectors and CCTV cameras. ITS Roadway Equipment
Roadway Environmental Monitoring 'Roadway Environmental Monitoring' measures environmental conditions and communicates the collected information back to a center where it can be monitored and analyzed or to other field devices to support communications to vehicles. 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
Roadway Signal Control 'Roadway Signal Control' includes the field elements that monitor and control signalized intersections. It includes the traffic signal controllers, detectors, conflict monitors, signal heads, and other ancillary equipment that supports traffic signal control. It also includes field masters, and equipment that supports communications with a central monitoring and/or control system, as applicable. The communications link supports upload and download of signal timings and other parameters and reporting of current intersection status. It represents the field equipment used in all levels of traffic signal control from basic actuated systems that operate on fixed timing plans through adaptive systems. It also supports all signalized intersection configurations, including those that accommodate pedestrians. In advanced, future implementations, environmental data may be monitored and used to support dilemma zone processing and other aspects of signal control that are sensitive to local environmental conditions. ITS Roadway Equipment
TIC Traffic Control Dissemination 'TIC Traffic Control Dissemination' serves as intermediary between transportation operations centers (e.g., TMC, Transit MC) and transportation users (e.g., vehicles, personal devices). It collects and disseminates intersection status, lane control information, special vehicle alerts, 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 collects traffic control information from Traffic Management and other Center(s) and disseminates the relevant information to vehicles and other mobile devices. Transportation Information 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 CACC Operations 'TMC CACC Operations' provides the back office functionality that supports formation and dissolution of strings of CACC-equipped vehicles and provides operating parameters including string length, recommended speeds, and gaps that take into account regional traffic and environmental conditions. 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
TMC Signal Control 'TMC Signal Control' provides the capability for traffic managers to monitor and manage the traffic flow at signalized intersections. This capability includes analyzing and reducing the collected data from traffic surveillance equipment and developing and implementing control plans for signalized intersections. Control plans may be developed and implemented that coordinate signals at many intersections under the domain of a single Traffic Management Center and are responsive to traffic conditions and adapt to support incidents, preemption and priority requests, pedestrian crossing calls, etc. Traffic Management Center
Vehicle Basic Safety Communication 'Vehicle Basic Safety Communication' exchanges current vehicle characteristics, location, and motion (including past and intended maneuver) information with other vehicles in the vicinity and the infrastructure, 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. 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 coordinate maneuvers and may, in addition to warning the driver, provide collision warning information to support automated control functions that can support control intervention. This object can also support broadcasting other vehicle information required for passing through a specific roadway segment such as variables that describe vehicle's characteristics and parameters, driver's preferences in terms of vehicle motion and behavior, etc. 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', receives warnings from 'Vehicle Intersection Movement', and uses the information about the area surrounding the vehicle to safely control the vehicle. This object can also use the planned trajectory and speed profile from 'Vehicle Eco-Driving Assist' to optimally control vehicle motion and will provide feedback on its execution of the received instructions back to 'Vehicle Eco-Driving Assist'. 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 Cooperative Cruise Control 'Vehicle Cooperative Cruise Control' uses V2V communications to share speeds and coordinate maneuvers with adjacent vehicles in the same lane (a CACC 'string'), maintaining vehicle speed and a safe gap with the predecessor vehicle. It provides the capability for vehicles to cluster into strings of CACC-equipped vehicles with compatible performance characteristics and share speed, location, acceleration/deceleration, path predictions (e.g., intended acceleration/deceleration) with other vehicles in the string. These capabilities are provided by systems on board the vehicle that coordinate with other vehicles and control acceleration and braking. In advanced implementations, the capability to coordinate with the infrastructure to support more advanced clustering strategies and use infrastructure provided target speed and traffic control information to improve performance. 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 Intersection Movement 'Vehicle Intersection Movement' uses short-range wireless communications to monitor other connected vehicles at intersections and support the safe movement of the vehicle through the intersection by receiving and processing signal phase and timing messages from the intersection. Driver warnings are provided and the application may also optionally take control of the vehicle to avoid collisions, in coordination with Vehicle Control Automation. The application will also notify the infrastructure and other vehicles if it detects an unsafe infringement on the intersection. Vehicle

Information Flow Security
Source Destination Information Flow Confidentiality Integrity Availability
Basis Basis Basis
Basic Vehicle Vehicle driver input information 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.
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.
ITS Roadway Equipment Traffic Management Center environmental sensor data Low Moderate Moderate
Little to no impact if this data is observed info should be correct to determine safe speeds etc.; DISC: WYO believes this to be HIGH Updates are desireable but slightly outdated information will not be catastrophic.
ITS Roadway Equipment Traffic Management Center signal control status Low High Moderate
The current conditions of an ITS RE are completely observable, by design. This influences the TMC response to a right-of-way request. It should be as accurate as the right-of-way request themselves. For some applications (ISIG) this need only be moderate. Per THEA: info needs to be accurate and should not be tampered to enable effective monitoring and control by the TMC. DISC: THEA believes this to be MODERATE: "info needs to be accurate and should not be tampered to enable effective monitoring and control by the TMC; should be as accurate as the right of way request". NYC:TMC doesn’t play an active role in this application, i.e. even if the information contained in this flow were incorrect, it is unlikely to affect the outcome of this application one way or the other. On some applications NYC has this MODERATE though. RES: This value can obviously change a lot depending on the application context. The TMC will need the current status of the ITS RE in order to make an educated decision. If it is unavailable, the system is unable to operate. However, a few missed messages will not have a catastrophic impact. From NYC: TMC doesn’t play an active role in this application, i.e. even if it is unavailable, it is unlikely to affect the outcome of this application one way or the other. RES: This value can change a lot depending on the application context.
ITS Roadway Equipment Traffic Management Center traffic detector data Low Moderate Moderate
No impact if someone sees the data Some minimal guarantee of data integrity is necessary for all C-ITS flows. THEA believes this to be LOW.only limited adverse effect if raw/processed traffic detector data is bad/compromised; DISC: WYO believes this to be HIGH Only limited adverse effect of info is not timely/readily available, however without this information it will be difficult to perform traffic management activities, thus MODERATE. If not used for management, may be LOW.
Other Vehicles Vehicle vehicle cluster coordination Low High Moderate
This data is intentionally transmitted to other vehicles operating in a vehicle cluster. Vehicle cluster coordination is critical to the performance of a group of vehicles in a vehicle cluster scenario. Incorrect data here is unlikely to trigger a severe accident scenario, but could have negative consequences on the performance of the cluster. Considered HIGH to be safe. Vehicle clustering scenarios cannot function without this flow. Worst case is non-initiation of the cluster however, which while significant to mobility does not have a direct severe consequence.
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 path prediction Not Applicable High Moderate
This data is intentionally transmitted to other vehicles operating in a cluster. Vehicle path data is critical to the performance of a group of vehicles in a vehicle cluster scenario. Incorrect data here could trigger a severe accident scenario. Some vehicle cluster scenarios cannot function without this flow. Worst case is that some vehicles will drop from the platoon however, which while significant to mobility does not have a direct severe consequence.
Other Vehicles Vehicle vehicle profile Low Moderate Moderate
This data is intentionally transmitted to other vehicles operating in a vehicle cluster. Vehicle profile data is critical to the performance of a group of vehicles in a vehicle cluster scenario. Incorrect data here could trigger a severe accident scenario. Vehicle clustering scenarios cannot function without this flow. Worst case is non-initiation of the platoon however, which while significant to mobility does not have a direct severe consequence.

Traffic Management Center ITS Roadway Equipment environmental sensor control Moderate Moderate Low
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. DISC: THEA, WYO believe this to be LOW: encrypted, authenticated, proprietary; but should not cause severe damage if seen Should be accurate and not be tampered with; could enable outside control of traffic sensors but should not cause severe harm, but could cause issues with environmental sensor data received and be detrimental to operations; DISC: WYO believes this may be HIGH for some applications 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. From THEAwant updates but delayed information will not be severe; should be able to operate from a previous/default control/config; DISC: WYO believes this to be MODERATE

DISC: THEA, WYO believe this to be LOW: encrypted, authenticated, proprietary; but should not cause severe damage if seen 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..

Traffic Management Center Traffic Operations Personnel traffic operator data Moderate Moderate Moderate
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. The backoffice system operator should have access to system operation. If this interface is down then control is effectively lost, as without feedback from the system the operator has no way of knowing what is the correct action to take.
Traffic Management Center Transportation Information Center intersection status Not Applicable Moderate Moderate
This data is distributed using a variety of mechanisms, some of which are localized broadcast; it is desireable that all potential users get this information. If this flow is not accurate or delivered in a timely fashion then a large variety of mobility and safety services that depend on it will not work properly. If this flow is not accurate or delivered in a timely fashion then a large variety of mobility and safety services that depend on it will not work properly.
Traffic Management Center Transportation Information Center speed management information Low Moderate Moderate
This information is directly observable. Wrong information would either falsely warn or advise the driver. DISC: WYO believes this to be HIGH. These notifications are helpful to a driver, if the driver does not receive this notification immediately, there should still be other visual cues

Vehicle Basic Vehicle driver update information Low Moderate Moderate
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 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.
