Physical Object Class Description
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.
Enforcement Center Center The 'Enforcement Center' represents the systems that receive reports of violations detected by various ITS facilities including individual vehicle emissions, lane violations, toll violations, CVO violations, etc.
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.
Light Vehicle Driver Vehicle The 'Light Vehicle Driver' represents the person that operates a light vehicle on the roadway. This physical object covers the interactions that are specific to light, passenger vehicles. See also the 'Driver' physical object that covers interactions that are shared by operators of light, transit, commercial, and emergency vehicles where the interactions are not particular to the type of vehicle.
Light Vehicle OBE Vehicle The 'Light Vehicle OBE' includes traveler-oriented capabilities that apply to passenger cars, trucks, and motorcycles that are used for personal travel. The rules vary by jurisdiction, but generally light vehicles are restricted in their weight and the maximum number of passengers they can carry. In ARC-IT, the Light Vehicle OBE represents vehicles that are operated as personal vehicles that are not part of a vehicle fleet and are not used commercially; thus, the choice between the various vehicle subsystems should be based more on how the vehicle is used than how much the vehicle weighs. See also the 'Vehicle' subsystem that includes the general safety and information services that apply to all types of vehicles, including light vehicles.
Other ITS Roadway Equipment Field Representing another set of ITS Roadway Equipment, 'Other ITS Roadway Equipment' supports 'field device' to 'field device' communication and coordination, and provides a source and destination for information that may be exchanged between ITS Roadway Equipment. The interface enables direct coordination between field equipment. Examples include the direct interface between sensors and other roadway devices (e.g., Dynamic Message Signs) and the direct interface between roadway devices (e.g., between a Signal System Master and Signal System Local equipment) or a connection between an arterial signal system master and a ramp meter controller.
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.
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.

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.

This data is sent to all drivers and is also directly observable, by design. This is the primary signal trusted by the driver to decide whether to go through the intersection and what speed to go through the intersection at; if it’s wrong, accidents will happen. If the lights are out you have to get a policeman to direct traffic – expensive and inefficient and may cause a knock-on effect due to lack of coordination with other intersections.

Any control flow has some confidentiality requirement, as observation of the flow may enable an attacker to analyze and learn how to assume control. MODERATE for most flows as the potential damage is likely contained, though anything that could have a significant safety impact may be assigned HIGH. Since this directly impacts device control, we consider it the same as a control flow. 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. Since this directly impacts device control, we consider it the same as a control flow. 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.

More or less important depending on the context. Could even be LOW if areas of minimal import, depending on local policies.
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.
Light Vehicle Driver Light Vehicle OBE light 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.
Light Vehicle OBE Light Vehicle Driver light vehicle 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.

Any control flow has some confidentiality requirement, as observation of the flow may enable an attacker to analyze and learn how to assume control. MODERATE for most flows as the potential damage is likely contained, though anything that could have a significant safety impact may be assigned HIGH. Since this directly impacts device control, we consider it the same as a control flow. 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. Since this directly impacts device control, we consider it the same as a control flow. 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.

Broadcast and intended for public consumtion. Should be correct or receiving vehicles may not take advantage of (if licensed) or violate (if not) limited access lanes. While there could be a safety impact, this is generally not the case. In areas with a noted significant safety impact due to illegitimate use of the limited access facility, this may be HIGH. Should be timely or receiving vehicles may not take advantage of (if licensed) or violate (if not) limited access lanes. While there could be a safety impact, this is generally not the case.
Traffic Management Center Connected Vehicle Roadside Equipment vehicle signage application info Moderate Moderate Moderate
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. If this is compromised, it could send unnecessary maintenance workers, or cause the appearance of excessive traffic violations, or not properly communicate areas where maintenance workers are operating for example. Not HIGH because regardless of the application, this flow alone does not directly drive injury or damage. DISC: WYO believes this to be HIGH. Control flow availability is related to the criticality of being able to remotely control the device. For most devices, this is MODERATE. This data should be received in a timely manner after it is sent. This will determine which lanes are blocked off for emergency vehicle use in incident management applications. 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.

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.
