VS09.3: C-ITS Reduced Speed Warning

Short range communications provides connected vehicles approaching a reduced speed zone with the posted speed limit, lane closure information, and vehicle-specific warnings for vehicles exceding the speed limit. The infrastructure monitors the short range communications, including vehicle-reported speed, and uses this to issue vehicle-specific speed warnings. This implementation Includes the CVRSE interfaces as fundamental and many of the alternative ITSRE interfaces become optional, but they are still included to support a real-world mix of equipped and unequipped vehicles.

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.
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.
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.
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.

Includes Functional Objects:

Functional Object Description Physical Object
MCM Reduced Speed Zone Warning 'MCM Reduced Speed Zone Warning' supports remote control and monitoring of reduced speed zone warning roadside equipment. It provides posted speed limits and associated schedules and information about associated road configuration changes including lane merges and shifts. It monitors field equipment operation and reports current status to the operator. Maint and Constr Management Center
Roadway Speed Monitoring and Warning 'Roadway Speed Monitoring and Warning' includes the field elements that monitor vehicle speeds. If the speed is determined to be excessive, an advisory or warning is displayed. Current environmental conditions and other factors that may reduce safe operating speeds may also be taken into account. The operational status (state of the device, configuration, and fault data) is provided to the center. This application can also provide an enforcement function, reporting speed violations to an enforcement agency. ITS Roadway Equipment
RSE Speed Warning 'RSE Speed Warning' notifies connected vehicles that are approaching a reduced speed zone, providing: (1) the zone’s current posted speed limit and (2) any roadway configuration changes associated with the reduced speed zone (e.g., lane closures, lane shifts) if applicable, and (3) associated warning information (i.e., the reason for the reduced speed warning). Configuration parameters that define the applicable speed limit(s), geographic location and extent of the reduced speed zone, and roadway configuration information are received from a center or provided through a local interface. The characteristics of individual vehicles may also be monitored and used to warn vehicles with specific limitations that reduce safe operating speeds, (e.g., rollover risk for tall vehicles). This functional object works in conjunction with the 'Roadway Speed Monitoring and Warning' functional object, which uses traditional ITS field equipment to warn non-equipped vehicles. Connected Vehicle Roadside Equipment
TMC Speed Warning 'TMC Speed Warning' supports remote control and monitoring of reduced speed zone warning roadside equipment. It provides the location and extent of the reduced speed zone, the posted speed limit(s) with information about the applicability of the speed limit(s) (e.g., time of day, day of week, seasonality, relevant vehicle types) and information about associated road configuration changes including lane merges and shifts. It monitors field equipment operation and reports current status to the operator. 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 Speed Management Assist 'Vehicle Speed Management Assist' assists the driver in operating the vehicle within the current speed limit. It monitors current vehicle speed and communicates with the infrastructure to receive current speed limits and associated road configuration change notifications. Driver warnings are issued when unsafe or excessive speeds are detected based on the provided speed limits and current conditions. Vehicle
Vehicle Traveler Information Reception 'Vehicle Traveler Information Reception' receives advisories, vehicle signage data, and other driver information of use to all types of vehicles and drivers and presents this information to the driver using in-vehicle equipment. Information presented may include fixed sign information, traffic control device status (e.g., signal phase and timing data), advisory and detour information, warnings of adverse road and weather conditions, travel times, and other driver information.

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.

For security monitoring objects such as security cameras this might be MODERATE, but the flow is marked as low since it is unlikely that those kinds of objects have shared control. If this flow is incorrect or manipulated then an unauthorized party may be able to gain control of a device, which can have significant effects. This is not a control flow however, so actual control is unlikely, thus MODERATE. Depends on the sharing arrangement, but generally interfaces between centers should provide timely response to enable proper decision making and action.
Traffic Management Center Connected Vehicle Roadside Equipment speed warning application info 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. info needs to be correct to issue correct speed limit and warnings or could cause driver confusion and delays or unsafe speed if compromised want updates but outdated information will not be catastrophic; should be able to operate on previous or default information
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.

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. From THEA: encrypted, authenticated, proprietary but shouldn’t cause substantial risk but does control speed enforcement systems 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 THEA: proprietary info that should not be tampered with; could directly affect safety if compromised posting unsafe speed limits, etc. 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. From THEA: want updates but outdated information will not be catastrophic; should be able to use previous/default config

Vehicle Basic Vehicle driver update information Low Moderate Moderate
This information is all presented to the vehicle operator. Encrypting this information may make it harder to reverse engineer vehicle systems, and may defeat criminal tracking tools when the vehicle has already been compromised. Unless those scenarios are of concern to the operator or manufacturer, this can safely be set LOW. Any information presented to the operator of a vehicle should be both accurate and timely. By definition this includes safety information, but given that the driver has other means of learning about most threats, it seems difficult to justify HIGH. If HIGH is warranted, it should apply to both availability and integrity. Any information presented to the operator of a vehicle should be both accurate and timely.

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 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.
