Physical Object Class Description
Basic Emergency Vehicle Vehicle The 'Basic Emergency Vehicle' represents the interfaces with on-board equipment on a public safety vehicle. It includes a specialized databus that may be subject to different vehicle databus standards and hosts a broad range of components that are specific to emergency vehicles including the lightbar/siren and on-board apparatus that supports law enforcement, firefighting, emergency medical services, and towing/recovery.
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 that are used to send messages to, and receive messages from, nearby vehicles using Dedicated Short Range Communications (DSRC) or other alternative wireless communications technologies. 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.
Emergency Management Center Center The 'Emergency Management Center' represents systems that support incident management, disaster response and evacuation, security monitoring, and other security and public safety-oriented ITS applications. It includes the functions associated with fixed and mobile public safety communications centers including public safety call taker and dispatch centers operated by police (including transit police), fire, and emergency medical services. It includes the functions associated with Emergency Operations Centers that are activated at local, regional, state, and federal levels for emergencies and the portable and transportable systems that support Incident Command System operations at an incident. This Center also represents systems associated with towing and recovery, freeway service patrols, HAZMAT response teams, and mayday service providers.

It manages sensor and surveillance equipment used to enhance transportation security of the roadway infrastructure (including bridges, tunnels, interchanges, and other key roadway segments) and the public transportation system (including transit vehicles, public areas such as transit stops and stations, facilities such as transit yards, and transit infrastructure such as rail, bridges, tunnels, or bus guideways). It provides security/surveillance services to improve traveler security in public areas not a part of the public transportation system.

It monitors alerts, advisories, and other threat information and prepares for and responds to identified emergencies. It coordinates emergency response involving multiple agencies with peer centers. It stores, coordinates, and utilizes emergency response and evacuation plans to facilitate this coordinated response. Emergency situation information including damage assessments, response status, evacuation information, and resource information are shared The Emergency Management Center also provides a focal point for coordination of the emergency and evacuation information that is provided to the traveling public, including wide-area alerts when immediate public notification is warranted.

It tracks and manages emergency vehicle fleets using real-time road network status and routing information from the other centers to aid in selecting the emergency vehicle(s) and routes, and works with other relevant centers to tailor traffic control to support emergency vehicle ingress and egress, implementation of special traffic restrictions and closures, evacuation traffic control plans, and other special strategies that adapt the transportation system to better meet the unique demands of an emergency.
Emergency Personnel Vehicle 'Emergency Personnel' represents personnel that are responsible for police, fire, emergency medical services, towing, service patrols, and other special response team (e.g., hazardous material clean-up) activities at an incident site. These personnel are associated with the Emergency Vehicle during dispatch to the incident site, but often work independently of the Emergency Vehicle while providing their incident response services.
Emergency Vehicle OBE Vehicle The Emergency Vehicle On-Board Equipment (OBE) resides in an emergency vehicle and provides the processing, storage, and communications functions that support public safety-related connected vehicle applications. It represents a range of vehicles including those operated by police, fire, and emergency medical services. In addition, it represents other incident response vehicles including towing and recovery vehicles and freeway service patrols. It includes two-way communications to support coordinated response to emergencies. A separate 'Vehicle OBE' physical object supports the general vehicle safety and driver information capabilities that apply to all vehicles, including emergency vehicles. The Emergency Vehicle OBE supplements these general capabilities with capabilities that are specific to emergency vehicles.
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.

Work zone systems including work zone surveillance, traffic control, driver warning, and work crew safety systems are also included.
Other EV OBEs Vehicle This represents on-board equipment on other emergency (e.g., law enforcement, fire, EMS, towing and recovery) vehicles. It provides a source and destination for ITS information transfers between emergency vehicles. These information transfers allow information to be shared between emergency vehicles arriving, or involved at, an incident. Vehicle to vehicle communications at incident locations facilitates incident coordination and personal safety.
Personnel Device Personal 'Personnel Device' represents devices used by emergency personnel or maintenance and construction personnel in the field. In the case of emergency personnel, the devices would include body cameras or smartphones (and their peripherals) that can be used by emergency personnel to provide images or video as well as send or receive data regarding the incident. The devices could also be used for incident scene safety messages to the personnel. In the case of maintenance and construction field personnel, the devices could be cellular phones or specialized safety devices that would be used for work zone safety messages to the personnel.
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.
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 OBE Vehicle The Vehicle On-Board Equipment (OBE) provides the vehicle-based sensory, processing, storage, and communications functions that support efficient, safe, and convenient travel. The Vehicle OBE includes general capabilities that apply to passenger cars, trucks, and motorcycles. 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 OBE 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 OBE. Both one-way and two-way communications options support a spectrum of information services from basic broadcast to advanced personalized information services. Route guidance capabilities assist in formulation of an optimal route and step by step guidance along the travel route. 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.

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.

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. May be LOW in some cases. If this is compromised, it could send unnecessary maintenance workers, or cause the appearance of non-existant incidents or even hide incident activities. Given that human safety could be involved, this might be HIGH. Incident status information should be presented in timely fashion as large scale mobility and safety issues are related. There are other mechanisms for reporting this information however, thus MODERATE.

Connected Vehicle Roadside Equipment Personnel Device personnel safety warning Not Applicable High Low
This data is intentionally transmitted to everyone via a broadcast. It can also be determined via other visual indicators. A few false warnings should not have a bad consequence. When an emergency personnel receives a warning they can look around and verify whether or not a vehicle is actually headed towards them. However, a message saying it is safe when there is a car coming could lead to an emergency personnel not moving when they were in danger. It would be better to receive any messages than to not have this application available due to availability requirements. However, the higher the availability here, the more useful the application will be and the more emergency personnel can rely on it.

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.
Emergency Management Center Connected Vehicle Roadside Equipment incident scene safety application info 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.

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 inaccurate information to a vehicle which could lead to inappropriate actions in the incident area. A delay in reporting this may cause a delay in response or inability for an Emergency Vehicle and its personnel to properly respond to the incident.
Emergency Management Center Emergency Vehicle OBE incident scene warning device control Moderate High 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. DISC: WYO believes this to be MODERATE. 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.

This data contains all of the information regarding the incident. This could include personal information regarding persons involved in the incident. It could also include sensitive information regarding special events or closures. Minor discrepancies in this data should not have a catastrophic effect, but it should be reasonably controlled and accurate. A few missed messages should not have a significant effect. However, most messages should make it through and the EMC should be able to know if the TMC has received a message.

This data is sent to all drivers and is also directly observable, by design. There are currently other visual and auditory indicators of an incident. Police will park their car with the lights (and possibly siren) on to indicate that a lane is closed. If incorrect information is sent to the driver, they will still have other cues indicating that an incident has occurred. If the current indicators are fully replaced by this system, then this would be raised to a HIGH. There are currently other visual and auditory indicators of an incident.

Emergency Vehicle OBE Emergency Management Center emergency vehicle tracking data Moderate Moderate Moderate
Emergency Vehicles give obvious visual and audio indicators about their location and operating status. Knowing the location of every single emergency vehicle within a city could be extremely useful information to a criminal. Additionally, although this is observable data, it is transmitted on a regional level, which means that someone who is able to intercept it would be able to read the location of all emergency vehicles, not just the ones they could directly observed. A sufficiently motivated criminal can however get this information by other means. Incorrect data here could lead to incorrect decisions being made about the closure of lanes, or incorrect information being shared with the emergency vehicles. There should be other indicators that would contradict incorrect information transmitted here. This information may be used to determine which emergency vehicle is dispatched, and having this information available could lead to a quicker response from the emergency vehicle. However, the system would still be able to operate properly if only most messages make it through.
Emergency Vehicle OBE Emergency Management Center incident scene status Moderate Moderate Moderate
Will include incident-specific information that could be used by a hostile attacker to target emergency resources, or to avoid those resources in the commission of a crime. Since this is used to coordinate emergency response, if this flow is unavailable, incorrect or corrupted the response may not be appropriate, comprimising safety and mobility. This system will be able to operate properly if most messages make it through. The emergency vehicle OBE should be able to know if the EMC received the message.

This flow is effectively broadcast and intended for all, so no need to obfuscate its contents. The recipient must be sure that the originator is legitimate, as many of these alerts demand action by the recipient (pull over, make way, etc.). Since this power could easily be abused, it should be difficult to forge. Since this power is also often tied to emergency vehicle (life-saving) activity, it should not be interfered with.

A lack of warning can have obvious catastrophic consequences, while a false warning could lead to users ignoring warnings due to perceived inaccuracy. Given that this triple may apply to highly dynamic environments (such as work zones), its accuracy is paramount, and thus if sent, must have HIGH integrity. There are other visual indicators about the geofenced areas. Personnel device users in dynamic environments (incident and work zones) should know when they are leaving a geofenced area.
