Physical Object Class Description
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.
Other Parking Management Centers Center Representing another parking facility's back office operations, 'Other Parking Management Centers' provides a source and destination for information that may be exchanged between peer parking systems. It enables parking management activities to be coordinated between different parking operators or systems in a region.
Other Transportation Information Centers Center Representing another Transportation Information Center, this object is intended to provide a source and destination for ITS information flows between peer information and service provider functions. It enables cooperative information sharing between providers as conditions warrant.
Parking Management Center Center The 'Parking Management Center' manages one or more parking lots by providing configuration and control of field infrastructure, user account management and interfaces with financial systems to manage payment. This p-object takes the back office portion of the Parking Management System's functionality as it was defined in ARC-IT 8.3 and prior.
Parking Manager Center 'Parking Manager' is the human operator that supports back office operations for one or more parking areas.
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.
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.

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 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.
Other Parking Management Centers Parking Management Center parking coordination Moderate Moderate Low
This should not include any PII, but may include pricing schedules, entry restrictions and similar data. May also include configurtion-related information; generally wise to obfuscate all of this information. Inter-agency and system-to-system coordination data needs to be correct or systems may not properly coordinate Should not need to be exchanged often.
Other Transportation Information Centers Transportation Information Center parking information Moderate Moderate Moderate
Does not include PII, but does include usage information for a managed facility that implies a number of vehicles. While this is observable information, it could be considered competitive, and regardless is accessible without being physically present, which is its own barrier. Generally transportation coordination information should be correct between source and destination, or inappropriate actions may be taken. Most likely not a frequently updated flow. Typically MODERATE for applications with a high degree of commercial vehicle parking, but could be LOW otherwise.

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 Parking Management Center parking traffic information Low Moderate Low
Provides some indication of regional traffic management strategies, which might be useful to an attacker, but that is far from obvious. Marked LOW unless a use case for an attack based on this information seems likely. If this flow were corrupted or modified then parking systems might not be able to cope with increased traffic as a result of regional management strategies. The impact will be inconvenience on the part of travelers, potentially many, but not a catastrophic event. Probably does not need to be updated often.
Traffic Management Center Parking Management Center transportation operational strategies Moderate Moderate Moderate
No PII is involved. However this flow should contain coordinated response information: how various transportation related entities respond to different conditions. This type of information is block intelligence that could be useful to an attacker or criminal, and thus should not be distributed in the clear. If this information is corrupted or modified, transportation management entities may not have well integrated plans for one or more operational scenarios, impacting mobility and safety in those conditions. Given that this data exchange is likely the product of personal work between agencies, and that follow up is likely, justify MODERATE and not HIGH. Probably not updated often, but could contain large amounts of information; additionally in times of crisis may need some more update, so MODERATE justifiable.
Transit Management Center Parking Management Center transit schedule adherence information Low Moderate Moderate
Eventually intended for public consumption, so no need to obfuscate. While accuracy of this data is important for decision making purposes, applications should be able to function without it. Thus MODERATE generally. While accuracy of this data is important for decision making purposes, applications should be able to cfunction without it. Thus MODERATE generally.
