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.
Field	Field	This general physical object is used to model core capabilities that are common to any piece of field equipment.
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 Field Personnel	Field	Represents the people that perform maintenance and construction field activities including vehicle and equipment operators, field supervisory personnel, field crews, and work zone safety personnel. Information flowing from the Maintenance and Construction Field Personnel will include those system inputs specific to maintenance and construction operations, such as information regarding work zone status, or the status of maintenance actions. The field personnel are also monitored within the work zone to enhance work zone safety. Information provided to Maintenance and Construction Field Personnel includes dispatch requests, maintenance and construction actions to be performed, and work zone safety warnings.
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.
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.

Field Asset Identification	'Field Asset Identification' stores and provides a unique identifier on request. The full range of RFID solutions are covered ranging from passive tags that support only near-field communications to active tags that support longer read ranges and writeable storage options. More advanced implementations can store and provide additional asset information in addition to the ID such as a lot number, production date, or last service date.	Field
MCM Field Asset Tracking	'MCM Field Asset Tracking' maintains a database of field assets and their locations. It shares this asset tracking data with other maintenance and construction applications that monitor and use the assets. It also identifies assets in travel lanes that may pose a safety hazard and shares this information for use in mitigating the safety risk through local vehicle warnings and maintenance crew notification.	Maint and Constr Management Center
Personnel Field Asset Locating	'Personnel Field Asset Locating' scans RFID-equipped assets and records their location relative to the scanning device. In this case, the scanning device is a handheld or portable system that is physical carried and used by field personnel. The asset locating system must know its location in 3D coordinates and calculate a range vector to the RFID tag. It can then provide the location and RFID ID to a back office service.	Personnel Device

Includes Information Flows:

Information Flow	Description
asset ID	A unique identification number and optional additional information. This flow represents the output of an RFID tag that is used for identification and tracking of assets, including both passive and active RFID tag technology options. For active tags, additional stored information that conveys additional information about the asset (e.g., lot number, production date, service data) may be provided along with the unique ID.
asset inventory	Information on pavement, bridges, signs and other assets. This includes asset location, installation information, materials information, vendor/contractor information, current maintenance status, and a variety of other information (e.g., video logs) that define the transportation infrastructure.
asset inventory locations	Current location and status of tracked asset inventory items.
asset locations	Aggregate collected data including identified assets and their locations.
maint and constr center personnel input	User input from maintenance and construction center personnel including routing information, scheduling data, dispatch instructions, device configuration and control, resource allocations, alerts, incident and emergency response plan coordination.
maint and constr operations information presentation	Presentation of maintenance and construction operations information to center personnel. This information includes maintenance resource status (vehicles, equipment, and personnel), work schedule information, work status, road and weather conditions, traffic information, incident information and associated resource requests, security alerts, emergency response plans and a range of other information that supports efficient maintenance and construction operations and planning.
personnel input	Field personnel input to a Personnel Device. This flow may provide input to applications operating on the Personnel Devices. This flow also establishes the settings that tailor each application to suit the user's needs.
personnel updates	Alerts and warnings provided to emergency personnel or work crew members. This includes visual, audio, and haptic outputs that may be customized to support individual needs.

Infrastructure information should be correct or maintenance assets may be inappropriately assigned.	Probably does not change very often, so the impact of loss of connectivity should be minimal.
Field	Personnel Device	asset ID	Low	Moderate	Moderate
Field	Personnel Device	asset ID	Unlikely that the ID of a particular asset, or even a group of assets would be useful to an attacker. Slight possibility, which is why Low vs. N/A.	Infrastructure information should be correct or maintenance assets may be inappropriately assigned, located or otherwise referenced.	Without this flow, asset location based safety applications may not function properly. The availability rating should mirror the importance of that service to the deployer. Generally if an operator goes to the trouble to track assets in the field this way, they consider this important and so the flow should be satisfied. Note that if an operator has multiple methods for tracking assets in the field, one instance of this flow could probably be reduced to LOW with minimal effect on service performance.

Maint and Constr Center Personnel	Maint and Constr Management Center	maint and constr center personnel input	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.	Backoffice operations flows should generally be correct and available as these are the primary interface between operators and system.

Maint and Constr Field Personnel	Personnel Device	personnel input	Input related to Emergency-related application. There could be sensitive information depending on the application, particularly regarding the health of someone involved in an incident the emergency personnel is responding to, in which case this rating might increase.	This data should be correct to enable accurate application functionality, but is likely not critical and easily corrected.	There should generally other ways to accomplish this flow.

Infrastructure information should be correct or maintenance assets may be inappropriately located, jeopardizing further uses, some of which involve safety.	Without this flow, asset location based safety applications may not function properly. The availability rating should mirror the importance of that service to the deployer.

Maint and Constr Management Center	Maint and Constr Center Personnel	maint and constr operations information presentation	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.
Personnel Device	Maint and Constr Field Personnel	personnel updates	Low	High	Moderate
Personnel Device	Maint and Constr Field Personnel	personnel updates	This data is informing the user of safety-related issues in the local transportation environment. It probably does not contain anything sensitive, and should not matter if another person can observe it.	This is the information that is presented to the individual in a work zone or incident response area that may be unpredictable in its formation. If the user receives incorrect information, they may act in an unsafe manner.	If this information is not made available to the pedestrian, then the user may be endangered. This is the not only mechanism the user may have to avoid potential dangers (they can observe directly).
Personnel Device	Maint and Constr Management Center	asset locations	Moderate	Moderate	Moderate
Personnel Device	Maint and Constr Management Center	asset locations	All observable information, and not easy to observe given that one end of the flow is moving around a construction site. However, observation at the non-moving end of the flow creates the "one stop shop", so should be protected from the nefarious for person looking for intrastructure targets.	Infrastructure information should be correct or maintenance assets may be inappropriately located, jeopardizing further uses, some of which involve safety.	Without this flow, asset location based safety applications may not function properly. The availability rating should mirror the importance of that service to the deployer. Generally if an operator goes to the trouble to track assets in the field this way, they consider this important and so the flow should be satisfied. Note that if an operator has multiple methods for tracking assets in the field, one instance of this flow could probably be reduced to LOW with minimal effect on service performance.
