ST10: Low Emissions Zone Management

The Low Emissions Zone Management service package supports the operation of a low emissions zone that is responsive to real-time traffic and environmental conditions. Low emissions zones are geographic areas that seek to restrict or deter access by specific categories of high-polluting vehicles into the area to improve the air quality within the geographic area. The service package uses data collected from vehicles using connected vehicle technologies and from roadside equipment as input to the system. The Low Emissions Zone Management service package supports the geo-fencing of a cordon that may be scalable and moveable (e.g., created for a day, removable, flexible in its boundaries) and would be less dependent on conventional ITS infrastructure. The service package would establish parameters including the types of vehicles permitted to enter the zone, exemptions for transit vehicles, emissions criteria for entering the zone, fees or incentives for vehicles based on emissions data collected from the vehicle, and geographic boundaries for the low emissions zone. The service package would also include electronic toll collection functions that support payments of fees or collection of incentives for registered vehicles using connected vehicle technologies. Finally, this service package provides information about the low emissions zone to traveler information centers, including information about criteria for entering the zone, expected fees and incentives, current and predicted traffic conditions, and geographic boundaries of the zone.

Includes Physical Objects:

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.
Emissions Management Operator Center The 'Emissions Management Operator' represents personnel that monitor, operate, and manage emissions monitoring and management systems. These personnel monitor system operation and monitor collected emissions and air quality information and direct system operation through data and command inputs.
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.
Event Promoter System Center 'Event Promoter System' represents Special Event Sponsors that have knowledge of events that may impact travel on roadways or other modal means. Examples of special event sponsors include sporting events, conventions, motorcades/parades, and public/political events. These promoters interface to the ITS to provide event information such as date, time, estimated duration, location, and any other information pertinent to traffic movement in the surrounding area.
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.
Payment Administration Center Center The 'Payment Administration Center' provides general payment administration capabilities and supports the electronic transfer of funds from the customer to the transportation system operator or other service provider. Charges can be recorded for tolls, vehicle-mileage charging, congestion charging, or other goods and services. It supports traveler enrollment and collection of both pre-payment and post-payment transportation fees in coordination with the financial infrastructure supporting electronic payment transactions. The system may establish and administer escrow accounts depending on the clearinghouse scheme and the type of payments involved. It may post a transaction to the customer account, generate a bill (for post-payment accounts), debit an escrow account, or interface to a financial infrastructure to debit a customer designated account. It supports communications with the ITS Roadway Payment Equipment to support fee collection operations. As an alternative, a wide-area wireless interface can be used to communicate directly with vehicle equipment. It also sets and administers the pricing structures and may implement road pricing policies in coordination with the Traffic Management Center.
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, 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) 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.

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 Event Promoter System low emissions zone operations information Moderate Moderate Low
While this information may eventually be public, it may contain details of emissions zone operations that could be used to abuse emissions zone systems. Emissions zone 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.
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.

This will include PII of the event contact person, which should be protected from casual viewing. This flow will also include details of the planned event, which in some circumstances might not be entire public information and so again, should not be casually viewable. Personal contact information needs to be correct, but so do the details of the planned event because of the potential severity of the event's impact. Generally the more significant the potential impact of the event, the higher this should be, but never below MODERATE. There should be other mechanisms for getting this information, otherwise it would match integrity.

ITS Roadway Equipment Connected Vehicle Roadside Equipment vehicle entries and exits Moderate Moderate Moderate
Directly observable data, but it is aggregated at the field device and also transmitted between devices; if a cyber-attacker were able to remotely monitor this feed, they might use this information to cause chaos. While this can be corroborated visually, the RSE may rely on this information to make mobility-related decisions with significant consequences, so the data must be of reasonable quality and availaability.. While this can be corroborated visually, the RSE may rely on this information to make mobility-related decisions with significant consequences, so the data must be of reasonable quality and availability.
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 Emissions Management Center air quality sensor data Not Applicable Moderate Low
Probably not sensitive information, no harm in this data being captured by unintended party. 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. This could be MODERATE if emissions information is critical to decision making.
ITS Roadway Equipment Emissions Management Center noise data Low Moderate Low
Probably not sensitive information, no harm in this data being captured by unintended party. At least some guarantee of correctness should be had with this data in case it is used for any analysis. If purely informative, could be LOW. Probably little impact if this is not available.
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 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.
ITS Roadway Equipment Traffic Management Center traffic detector data Low Moderate Moderate
No impact if someone sees the data Some minimal guarantee of data integrity is necessary for all C-ITS flows. THEA believes this to be LOW.only limited adverse effect if raw/processed traffic detector data is bad/compromised; DISC: WYO believes this to be HIGH Only limited adverse effect of info is not timely/readily available, however without this information it will be difficult to perform traffic management activities, thus MODERATE. If not used for management, may be LOW.
Payment Administration Center Emissions Management Center low emissions zone coordination Moderate Moderate Low
While this information may eventually be public, it may contain details of emissions zone operations that could be used to abuse emissions zone systems. Configuration functions should have their integrity protected to avoid misconfiguration which could result in revenue or operational losses. Probably not a huge impact if this information cannot be updated frequently, thus LOW. If the priority of the low emission zone is high (to the jurisdiction in question) this could be MODERATE.
Traffic Management Center Connected Vehicle Roadside Equipment controlled zone application info 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.
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.
Traffic Management Center Emissions Management Center low emissions zone coordination Moderate Moderate Low
While this information may eventually be public, it may contain details of traffic demand information that could be used to abuse the roadway network. Configuration functions should have their integrity protected to avoid misconfiguration which could result in revenue or operational losses.

Traffic Management Center Emissions Management Center road network conditions Low Moderate Moderate
No harm should come from seeing this data, as it is eventually intended for public consumption. While accuracy of this data is important for decision making purposes, applications should be able to corroborate the data in many instances. Thus MODERATE generally. Depends on the application; if mobility decisions that affect large numbers of travelers are made based on this data, then it is MODERATE. In more modest circumstances, it may be LOW.

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 ITS Roadway Equipment traffic detector 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. DISC: THEA, WYO believe this to be LOW: encrypted, authenticated, proprietary; but should not cause severe damage if seen 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: should be accurate and not be tampered with; could enable outside control of traffic sensors but should not cause severe harm, but could cause issues with traffic sensor data received and be detrimental to operations 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 delayed information will not be severe; should be able to operate from a previous/default control/config. DISC: WYO believes this to be MODERATE
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.
Traffic Operations Personnel Traffic Management Center traffic operator input Moderate High High
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.

While this information may eventually be public, it may contain details of transit operations that could be used to abuse transit systems. Configuration functions should have their integrity protected to avoid misconfiguration which could result in revenue or operational losses. Probably not a huge impact if this information cannot be updated frequently, thus LOW.
Transit Management Center Emissions Management Center transit and fare schedules Low Moderate Moderate
Does not contain any personal or confidential information. While accuracy of this data is important for decision making purposes, the greatest impact if manipulated or incorrect data would be financial and likely limited in scope. For example, making all options appear less expensive than an attacker's route of fiduciary interest, driving revenue to his route. This is undesireable and significant, but not catastrophic. Thus MODERATE generally. While accuracy of this data is important for decision making purposes, applications should be able to function without frequent updates. Thus MODERATE generally, though it could be LOW depending on the level of projected updates.
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 Connected Vehicle Roadside Equipment vehicle reported emissions Moderate Moderate Moderate
Contains PII describing the vehicle and its operating characteristics, which if observed could be used against the vehicle owner. 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.
Vehicle Characteristics ITS Roadway Equipment vehicle characteristics
Weather Service System Emissions Management Center weather information Low Moderate Low
Typically intended for public distribution. While there are many sources of weather information, some guarantee of correctness is justifiable to keep confidence in provided service. There should be other sources of this data. It does need to be reliable however; weather can change quickly, and depending on the destination and its operational strategies, timely response may be important.
