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 (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.
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.
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 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.

Includes Functional Objects:

Functional Object Description Physical Object
Roadway Dynamic Lane Management and Shoulder Use 'Roadway Dynamic Lane Management and Shoulder Use' includes the field equipment, physical overhead lane signs and associated control electronics that are used to manage and control specific lanes and/or the shoulders. This equipment can be centrally controlled by a Traffic Management Center or it can be autonomous and monitor traffic conditions and demand along the roadway and determine how to change the lane controls to respond to current conditions. Lane controls can be used to change the lane configuration of the roadway, reconfigure intersections and/or interchanges, allow use of shoulders as temporary travel lanes, designate lanes for use by special vehicles only, such as buses, high occupancy vehicles (HOVs), vehicles attending a special event, etc. and/or prohibit or restrict types of vehicles from using particular lanes. Guidance and information for drivers can be posted on dynamic message signs. ITS Roadway Equipment
Roadway Traffic Information Dissemination 'Roadway Traffic Information Dissemination' includes field elements that provide information to drivers, including dynamic message signs and highway advisory radios. ITS Roadway Equipment
RSE Restricted Lanes Application The 'RSE Restricted Lanes Application' uses short range communications to monitor and manage dynamic and static restricted lanes. It collects vehicle profile information from vehicles entering the lanes and monitors vehicles within the lanes, providing aggregate data to the back office center. It provides lane restriction information and signage data to the vehicles and optionally identifies vehicles that violate the current lane restrictions. These functions are performed based on operating parameters provided by the back office managing center(s). 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
TMC Dynamic Lane Management and Shoulder Use 'TMC Dynamic Lane Management and Shoulder Use' remotely monitors and controls the system that is used to dynamically manage travel lanes, including temporary use of shoulders as travel lanes. It monitors traffic conditions and demand measured in the field and determines when the lane configuration of the roadway should be changed, when intersections and/or interchanges should be reconfigured, when the shoulders should be used for travel (as a lane), when lanes should be designated for use by special vehicles only, such as buses, high occupancy vehicles (HOVs), vehicles attending a special event, etc. and/or when types of vehicles should be prohibited or restricted from using particular lanes. It controls the field equipment used to manage and control specific lanes and the shoulders. It also can automatically notify the enforcement agency of lane control violations. Traffic Management Center
TMC In-Vehicle Signing Management 'TMC In-Vehicle Signing Management' controls and monitors RSEs that support in-vehicle signing. Sign information that may include static regulatory, service, and directional sign information as well as variable information such as traffic and road conditions can be provided to the RSE, which uses short range communications to send the information to in-vehicle equipment. Information that is currently being communicated to passing vehicles and the operational status of the field equipment is monitored by this application. The operational status of the field equipment is reported to operations personnel. Traffic Management Center
TMC Restricted Lanes CV Application 'TMC Restricted Lanes CV Application' manages dynamic lanes for connected vehicles. The application provides the back office functions and supports the TMC operator in establishing and managing dynamic lanes using communications to manage lane use for connected vehicles. Traffic Management Center
TMC Traffic Information Dissemination 'TMC Traffic Information Dissemination' disseminates traffic and road conditions, closure and detour information, incident information, driver advisories, and other traffic-related data to other centers, the media, and driver information systems. It monitors and controls driver information system field equipment including dynamic message signs and highway advisory radio, managing dissemination of driver information through these systems. 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 Restricted Lanes Application The 'Vehicle Restricted Lanes Application' monitors and reports its own operating parameters and communicates with roadside equipment to safely enter, operate within, and exit restricted lanes that are relevant to all types of vehicles. Vehicle

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.

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.
Connected Vehicle Roadside Equipment ITS Roadway Equipment restricted lanes 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.

DISC: WYO believes this to be LOW 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 restricted lanes information Not Applicable Moderate Moderate
Broadcast and intended for public consumption. 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.
Connected Vehicle Roadside Equipment Vehicle vehicle signage data Low Moderate Moderate
This data is intentionally transmitted to everyone via a broadcast. It is meant to augment other signage data, and by definition is meant to be shared with everyone. These signs are meant to augment other visual cues to the driver. They should be accurate, but any inaccuracies should be corrected for by other means. These notifications are helpful to a driver, but if the driver does not receive this notification immediately, there should still be other visual cues.
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 Connected Vehicle Roadside Equipment vehicle signage local data Low Moderate Moderate
This data is intentionally transmitted to everyone via a broadcast. It is meant to augment other signage data, and by definition is meant to be shared with everyone. This information impacts the vehicle signage data sent to neighboring ASDs and should be trusted to avoid sending wrong information. DISC: WYO believes this to be HIGH. The system should know if these messages are not received.
ITS Roadway Equipment Driver driver information Not Applicable High Moderate
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 could happen. If the lights are out you have to get a policeman to direct traffic – expensive and inefficient and may cause a cascading effect due to lack of coordination with other intersections.
ITS Roadway Equipment Traffic Management Center lane management information Moderate Moderate Moderate
May contain PII, may contain source data describing device control and sensed status that if captured could be used in the commission of a crime or breaking of traffic laws or regulations. Information related to violations must be correct so that incorrect accusations are not made. Information related to device status and control must be correct to avoid wasted maintenance efforts. 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 roadway dynamic signage status Moderate Moderate Moderate
Device status information should not be available, as those with criminal intent may use this information toward their own ends. Data is intended to feed dissemination channels, either C-ITS messages or DMS or other channels, so it should generally be correct as it is distributed widely and any forgery or corrupted data will have widespread impact. Failure of this flow affects traveler information dissemination, the importance of which varies with the data contained in the flow and the scenario. Could be LOW in many instances.

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.

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.
Traffic Management Center ITS Roadway Equipment roadway dynamic signage data Moderate Moderate Moderate
Device control information should not be available, as those with criminal intent may use this information toward their own ends. Data is intended to feed dissemination channels, either C-ITS messages or DMS or other channels, so it should generally be correct as it is distributed widely and any forgery or corrupted data will have widespread impact. Occasional outages of this flow will delay dissemination of the data to travelers (the eventual end user) which could have significant impacts on travel, both safety and mobility impacts.
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.

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. Backoffice operations flows should generally be correct and available as these are the primary interface between operators and system.

Vehicle Connected Vehicle Roadside Equipment vehicle location and motion for surveillance Not Applicable Moderate Moderate
This is directly observable data; DISC: WYO believes this to be MODERATE Incorrect information here could lead to the system not functioning properly. If they are unable to properly detect all vehicles crossing the border, it would lead to confusion. There are other factors, such as visual indicators, of vehicles crossing the border, which can be used to help mitigate contradicting information. DISC: THEA believes this should be HIGH: "BSM info needs to be accurate and should not be tampered with" WYO believes this to be HIGH This information must be available in a timely manner for the system to act upon it. The system can operate correctly if some messages are missed, but overall a majority of them should be received.; WYO believes this to be LOW
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.
