MC12: One-Way Convoy Driving
This service package enables convoys through areas restricted to one-way travel by maintenance and construction, heavy snowfalls, or other obstructions. Typically these are long stretches of roadway that require escort due to excessive speed concerns, crossroads, lane changes, equipment crossings, or adverse conditions. Maintenance vehicles assemble groups of vehicles and serve as pilot vehicles (lead and optional chase vehicles) for the convoy. Notification of convoy operations occurs through traditional traveler information methods.

Includes Physical Objects:
| Physical Object | Class | Description |
|---|---|---|
| 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. |
| Light Vehicle Driver | Vehicle | The 'Light Vehicle Driver' represents the person that operates a light vehicle on the roadway. This physical object covers the interactions that are specific to light, passenger vehicles. See also the 'Driver' physical object that covers interactions that are shared by operators of light, transit, commercial, and emergency vehicles where the interactions are not particular to the type of vehicle. |
| Light Vehicle OBE | Vehicle | The 'Light Vehicle OBE' includes traveler-oriented capabilities that apply to passenger cars, trucks, and motorcycles that are used for personal travel. The rules vary by jurisdiction, but generally light vehicles are restricted in their weight and the maximum number of passengers they can carry. In ARC-IT, the Light Vehicle OBE represents vehicles that are operated as personal vehicles that are not part of a vehicle fleet and are not used commercially; thus, the choice between the various vehicle subsystems should be based more on how the vehicle is used than how much the vehicle weighs. See also the 'Vehicle' subsystem that includes the general safety and information services that apply to all types of vehicles, including light vehicles. |
| 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. |
| Other MCV OBEs | Vehicle | This represents on-board equipment on other maintenance and construction vehicles. It provides a source and destination for ITS information transfers between maintenance and construction vehicles. These information transfers allow vehicle operational status, environmental information, and work zone intrusion warnings or alarms to be shared between vehicles. |
| Personal Information Device | Personal | The 'Personal Information Device' provides the capability for travelers to receive formatted traveler information wherever they are. Capabilities include traveler information, trip planning, and route guidance. Frequently a smart phone, the Personal Information Device provides travelers with the capability to receive route planning and other personally focused transportation services from the infrastructure in the field, at home, at work, or while en-route. Personal Information Devices may operate independently or may be linked with vehicle on-board equipment. This subsystem also supports safety related services with the capability to broadcast safety messages and initiate a distress signal or request for help. |
| 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. |

| May contain surveillance data; if that data includes license plates or other imagery, observation by a third party should be discouraged at this point (public camera data may be republished under other flows, but as chosen by the operator). Without such personally-focused surveillance data, this may be LOW. | Since this reports the status of reversible controls, any corruption or modification could have a catastrophic impact (if the center though the lanes were open in the opposite direction and allowed head-on traffic into the lanes). However, any such reversing should be accompanied by verification, either by camera or direct visual inspection, justifying lowering this to MODERATE. | Reversible lane controls should always be accessible, however this status flow will be supported by another, generally visual confirmation. | |||

| There should be little harm to come from knowing who controls what field device in most instances. 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.

| Traffic Management Center | ITS Roadway Equipment | reversible lane 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. | 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. | |||
