Includes Physical Objects:

Physical Object Class Description
Asset Management System Center 'Asset Management System' represents the systems that support decision-making for maintenance, upgrade, and operation of physical transportation assets. Asset management integrates and includes the pavement management systems, bridge management systems, and other systems that inventory and manage the highway infrastructure and other transportation-related assets. The types of assets that are inventoried and managed will vary, and may include the maintenance and construction vehicles and equipment as well as "soft" assets such as human resources and software. Asset management systems monitor the condition, performance, and availability of the infrastructure and evaluate and prioritize alternative reconstruction, rehabilitation, and maintenance strategies.
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.
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.
Maint and Constr Center Personnel Center The people that directly interface with a Maintenance and Construction Management Center. These personnel interact with fleet dispatch and management systems, road maintenance systems, incident management systems, work plan scheduling systems, and work zone 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.
Maint and Constr Management Center Center The 'Maint and Constr Management Center' monitors and manages roadway infrastructure construction and maintenance activities. Representing both public agencies and private contractors that provide these functions, this physical object manages fleets of maintenance, construction, or special service vehicles (e.g., snow and ice control equipment). The physical object receives a wide range of status information from these vehicles and performs vehicle dispatch, routing, and resource management for the vehicle fleets and associated equipment. The physical object participates in incident response by deploying maintenance and construction resources to an incident scene, in coordination with other center physical objects. The physical object manages equipment at the roadside, including environmental sensors and automated systems that monitor and mitigate adverse road and surface weather conditions. It manages the repair and maintenance of both non-ITS and ITS equipment including the traffic controllers, detectors, dynamic message signs, signals, and other equipment associated with the roadway infrastructure. Weather information is collected and fused with other data sources and used to support advanced decision support systems.

The physical object remotely monitors and manages ITS capabilities in work zones, gathering, storing, and disseminating work zone information to other systems. It manages traffic in the vicinity of the work zone and advises drivers of work zone status (either directly at the roadside or through an interface with the Transportation Information Center or Traffic Management Center physical objects.)

Construction and maintenance activities are tracked and coordinated with other systems, improving the quality and accuracy of information available regarding closures and other roadway construction and maintenance activities.
Maint and Constr Vehicle OBE Vehicle The 'Maint and Constr Vehicle OBE' resides in a maintenance, construction, or other specialized service vehicle or equipment and provides the processing, storage, and communications functions necessary to support highway maintenance and construction. All types of maintenance and construction vehicles are covered, including heavy equipment, supervisory vehicles, unmanned remote controlled field maintenance robots, and sensory platforms that may be wheeled or low altitude aerial vehicles (e.g. drones, balloons). The MCV OBE provides two-way communications between drivers/operators and dispatchers and maintains and communicates current location and status information. A wide range of operational status is monitored, measured, and made available, depending on the specific type of vehicle or equipment. A snow plow for example, would monitor whether the plow is up or down and material usage information. The Maint and Constr Vehicle OBE may also contain capabilities to monitor vehicle systems to support maintenance of the vehicle itself. A separate 'Vehicle OBE' physical object supports the general vehicle safety and driver information capabilities that apply to all vehicles, including maintenance and construction vehicles. The Maint and Constr Vehicle OBE supplements these general capabilities with capabilities that are specific to maintenance and construction vehicles.
Maint and Constr Vehicle Operator Vehicle The operator of maintenance, construction, or other specialized service vehicles or equipment. Represents the maintenance and construction vehicle operators. The operator provides input specific to maintenance and construction vehicle operations, including the status of maintenance actions. Information provided to the operator includes dispatch requests and maintenance and construction actions to be performed.
Vehicle Vehicle This 'Vehicle' physical object is used to model core capabilities that are common to more than one type of Vehicle. It provides the vehicle-based general sensory, processing, storage, and communications functions that support efficient, safe, and convenient travel. Many of these capabilities (e.g., see the Vehicle Safety service packages) apply to all vehicle types including personal vehicles, commercial vehicles, emergency vehicles, transit vehicles, and maintenance vehicles. From this perspective, the Vehicle includes the common interfaces and functions that apply to all motorized vehicles. The radio(s) supporting V2V and V2I communications are a key component of the Vehicle. Both one-way and two-way communications options support a spectrum of information services from basic broadcast to advanced personalized information services. Advanced sensors, processors, enhanced driver interfaces, and actuators complement the driver information services so that, in addition to making informed mode and route selections, the driver travels these routes in a safer and more consistent manner. This physical object supports all six levels of driving automation as defined in SAE J3016. Initial collision avoidance functions provide 'vigilant co-pilot' driver warning capabilities. More advanced functions assume limited control of the vehicle to maintain lane position and safe headways. In the most advanced implementations, this Physical Object supports full automation of all aspects of the driving task, aided by communications with other vehicles in the vicinity and in coordination with supporting infrastructure subsystems.

Field situation data should include only directly observable data. However, this information flow could include a huge volume, and could be highly aggregated and/or valuable. Some protection of this information is justified given the scope of the data and the knowledge that could be gleaned by illicit observation of this flow. Situation data will be used for a variety of decision-making purposes, so it should have some error checking, as any corruption could lead to sub-optimal choices. While any given instance of this flow is not critical, the aggregation of all will be significant. This could be the primary source of field situation data for many centers. Given this potential reliance, HIGH is warranted. If in a particular area the data is "nice to have but not necessary" this might be lowered to MODERATE or even LOW, depending on the data types and uses for that data by subscribers.

May be MODERATE if little such data is available or assets and potential impact is limited. Real-time monitoring of transportation asset data should be accurate and timely to protect the monitored assets. Given that the destintation of this flow cannot act directly, it is difficult to justify HIGH, unless 'infrastructure situation data' does not exist. As this flow includes data that reflects the condition of transportation assets, and can be used to infer the safety of use of those assets, loss of this flow means loss of asset safety monitoring, which has a potentially significant impact.

Direct interactions between personnel and systems in a backoffice environment are effectively protected by physical means, so long as the interaction is in a dedicated facility. If this interaction is virtual (i.e. ,the MCMC is not directly in front of the MCMC Personnel, like in a cloud-based system) then the user's input requires some degree of obfuscation depending on sensitivity of information. Given that this could include information about compromised or ineffectual systems, including security systems, the potential for damage is high. Thus, HIGH.

Linked to the asset inventory, so the same concerns with this flow as that one, namely that when placed in one spot becomes a "one stop shop" for a nefarious person looking for infrastructure targets. Given the narrow focus of this flow it might be LOW, except that it infers information about specific targets. Infrastructure information should be correct or maintenance assets may be inappropriately assigned. While this changes more than other asset flows, the impact should still be minimal.

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.

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: NYC believes this to be low: "This information is directly observable." 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. From NYC: The information sent from TMC directly affect the ITS-RE speed "announcement". 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..

System maintenance flows should have some protection from casual viewing, as otherwise imposters could gain illicit control over field equipment 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.

Infrastructure sensor data may or may not be sensitive. Performance of sensors should be limited to maintenance personnel in case someone with hostile intent would monitor this data looking for particular conditions. This is a tenous leap in need for confidentiality; depending on the potential for conditions that can be sensed that might be abused for damage, this might be reduced to LOW. Sensor status, sensor data should have some degree of confidence, or decisions attached to this data may be erroneous. Assessment of MODERATE assumes sensors identifying conditions that move actions on the part of the M&CMC. For instance, icing, or radical changes in atmospheric condistions suggestion traffic management or road maintenance challenges.

Observation of control or status information is unlikely to have any value to a third party; actions of field personnel should be observable anyway. Any driver/operator interaction with vehicle systems needs some assurance of correctness; corruption of this information could lead to unexpected vehicle behavior which poses a limited safety risk. Without direct local control of vehicle systems the vehicle is essentially uncontrolled.
Vehicle Connected Vehicle Roadside Equipment vehicle environmental data Low Moderate Low
Little abusive potential for capturing the information in this flow as designed. Could be moderate if this contains PII related information, but considered for now to not include any PII; DISC: WYO believes Vehicle to Center versions of this flow to be MODERATE as center penetrations could more easily garner aggregate user data that might be used for mischief. Some minimal guarantee of data integrity is necessary for all C-ITS flows. DISC THEA believes this to be LOW: Data should be accurate and not tampered with but should be able to cope with some bad data in traffic/environmental condition monitoring; aggregate data; can also receive data from ITS RE; DISC: WYO believes this to be MODERATE data should be timely and readily available, but limited adverse effect; aggregate data; can also receive data from ITS RE; DISC: WYO believes this to be MODERATE
