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.
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.
Emissions Management Center Center The 'Emissions Management Center' provides the capabilities for air quality managers to monitor and manage air quality. These capabilities include collecting emissions data from distributed emissions sensors (included in ITS Roadway Equipment) and directly from connected vehicles. The sensors monitor general air quality and also monitor the emissions of individual vehicles on the roadway. The measures are collected, processed, and used to support environmental monitoring applications.
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.
Other Traffic Management Centers Center Representing another Traffic Management Center, 'Other Traffic Management Centers' is intended to provide a source and destination for information exchange between peer (e.g. inter-regional) traffic management functions. It enables traffic management activities to be coordinated across different jurisdictional areas.
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.
Transit Management Center Center The 'Transit Management Center' manages transit vehicle fleets and coordinates with other modes and transportation services. It provides operations, maintenance, customer information, planning and management functions for the transit property. It spans distinct central dispatch and garage management systems and supports the spectrum of fixed route, flexible route, paratransit services, transit rail, and bus rapid transit (BRT) service. The physical object's interfaces support communication between transit departments and with other operating entities such as emergency response services and traffic management systems.
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.

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 Regional Traffic Management 'TMC Regional Traffic Management' supports coordination between Traffic Management Centers in order to share traffic information between centers as well as control of traffic management field equipment. This coordination supports wide area optimization and regional coordination that spans jurisdictional boundaries; for example, coordinated signal control in a metropolitan area or coordination between freeway operations and arterial signal control within a corridor. 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.

lane management information System status of managed lanes including current operational state, violations, and logged information. This includes lane usage information including both traditional traffic flow measures and special information associated with managed lanes such as measured passenger occupancies. It also includes the operational status of the lane management equipment.
lane violation notification Notification to enforcement agency of detected lane entry violations, lane speed violations, or other dynamic lane violations. Lane entry violations may be issued for restricted vehicle types or vehicles that do not meet required emissions or passenger occupancy standards that enter a managed lane. This notification identifies the vehicle and documents the lane parameter that was violated.
restricted lanes application info Restricted lane application configuration data and messaging parameters. This flow defines the location, duration, and operating parameters for lanes that are reserved for the exclusive use of certain types of vehicles (e.g., transit vehicles) or vehicles that meet other qualifications (e.g., number of occupants, low emissions criteria). It may also identify additional vehicles that may be allowed in the lanes as exceptions, though they don't meet specified criteria. It identifies the lane(s), the start and stop locations, start and end times, vehicle restrictions, speed limits and platooning parameters. This flow also supports remote control of the application so the application can be taken offline, reset, or restarted.
restricted lanes application status Current RSE application status that is monitored by the back office center including the operational state of the RSE, current configuration parameters, and a log of lane use (aggregate profiles of vehicles that checked in to the lane and reported vehicle speeds in the lanes) and RSE communications activity.

Probably not sensitive information, no harm in this data being captured by unintended party. This flow does not correlate specific vehicles with any emissions data. At least some guarantee of correctness should be had with this data. It could be used to modify transit/traffic strategies over a large area ("its a code ORANGE day out there, don't run") that change behavior for a large number of people.

May contain PII of a black listed user account, and/or vehicle identification. Given the potential for PII to be involved, this needs to be correct and unalterable to avoid confusion or malfeasance. Availability is at least MODERATE since the information has potential legal (or at least traffic law) implications that would otherwise involve a far less prompt and possibly manpower intensive interaction.
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.
Emissions Management Center Connected Vehicle Roadside Equipment emissions monitoring application information Moderate Moderate Low
This is a control flow, so should be obfuscated to make it more difficult for a 3rd party to manipulate the RSE. Control parameters need to be correct and not corrupted so that the owner of the RSE and the receiver of the RSE's data get what they need from it. This information probably does not need to be changed very often, and if it is not available then likely the flow it controls (emissions data flows to the DDS/EMC) are down as well.
Emissions Management Center Enforcement Center emissions violation notification Moderate Moderate Moderate
Contains PII and intended to be used for enforcement. Thus privacy implications that, while they may affect only a single individual at a time, could yield significant negative consequences to that individual. Violation information needs to be correct or the vehicle may be improperly penalized, or not when it should be. This is probably not a severe consequence however, so MODERATE. More or less important depending on the context. Could even be LOW if areas of minimal import, depending on local policies.
Emissions Management Center ITS Roadway Equipment air quality 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. 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.

While this information may eventually be public, it may contain details of an emissions incident that could require further investigation; third party observation of this information could hamper that investigation. Emissions incident information should have its integrity protected to avoid misinformation or confusion that could result from incorrect data dissemination. Probably not a huge impact if this information cannot be updated frequently, thus LOW. If traffic management in the area is reactive to emissions and pollution in general, this may be increased to 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 Emissions Management Center vehicle emissions data Moderate Moderate Low
Contains vehicle identity, which should be protected from casual viewing, and maps that to various emissions parameters. As this may imply legal issues (over-emitting etc.), the data should be kept confidential to protect the vehicle owner. As this contains information that could be used to grant permitting (emissions passing) or issue penalites (over-emitting), a corruption of this data could result in the wrong action being taken, revenue lost or inappropriately gained, permit incorrectly granted or denied. Could be MODERATE for those areas where emissions are high priority items. Generally LOW given that most emissions testing is done in person now. As systems come to rely on remote sensing, this may become MODERATE.
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.

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.

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.

Applications relying on this data will not function properly if the data is incorrect, so it must be protected commensurate to the value of the application. Initially MODERATE, unlikely to be set to HIGH unless emissions operations are the highest priority. Important for low emissions zone operations; without accurate and timely information, applications relying on this data will not function. While initially MODERATE, could be LOW if the priority for emissions-related applications are similarly low.
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.
