Includes Physical Objects:

Physical Object Class Description
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.
Map Update System Support The 'Map Update System' represents a provider of map databases used to support ITS services. It supports the provision of the map data that are used directly by vehicles (e.g., roadway and intersection geometry data sets), travelers (e.g., navigable maps used for route guidance and display maps used at traveler information points), system operators (e.g., map data used by Traffic Operators to monitor and manage the road network, and map data used by Fleet Managers to manage a vehicle fleet). It may represent a third-party provider or an internal organization that produces map data for agency use. In the latter case, the 'Map Update System' is typically included as part of the center (e.g., a Traffic Management Center) of the infrastructure owner/operator that manages map data. Products may include simple display maps, map data sets that define detailed road network topology and geometry, or full geographic information system databases that are used to support planning and operations.
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.
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 connected vehicle on-board equipment.
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 Regulatory Authority Center Center The 'Traffic Regulatory Authority Center' is the authoritative source for traffic rules, regulations, ordinances and statutes that have official status and must be understood by all motor vehicle operators and intelligent vehicles that operate at higher automation levels. This center may represent multiple authorities that operate at local, regional, state, and national levels and represents organizations that establish, manage, and enact the traffic code.
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.
Traveler Personal The 'Traveler' represents any individual who uses transportation services. The interfaces to the traveler provide general pre-trip and en-route information supporting trip planning, personal guidance, and requests for assistance in an emergency that are relevant to all transportation system users. It also represents users of a public transportation system and addresses interfaces these users have within a transit vehicle or at transit facilities such as roadside stops and transit centers.
Vehicle OBE Vehicle The Vehicle On-Board Equipment (OBE) provides the vehicle-based sensory, processing, storage, and communications functions that support efficient, safe, and convenient travel. The Vehicle OBE includes general capabilities that apply to passenger cars, trucks, and motorcycles. 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 OBE 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 OBE. Both one-way and two-way communications options support a spectrum of information services from basic broadcast to advanced personalized information services. Route guidance capabilities assist in formulation of an optimal route and step by step guidance along the travel route. 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.

Includes Functional Objects:

Functional Object Description Physical Object
Map Management 'Map Management' provides the GIS functionality necessary to support map data creation and management. It provides an operator interface that supports management of the map data and rendering of the maps under operator control and interfaces to external data sources, including the connected vehicle environment. Map Update System
Personal Traveler Information Reception 'Personal Traveler Information Reception' receives formatted traffic advisories, road conditions, traffic regulations, transit information, broadcast alerts, and other general traveler information broadcasts and presents the information to the traveler. The traveler information broadcasts are received by personal devices including personal computers and personal portable devices such as smart phones. Personal Information Device
TIC Data Collection 'TIC Data Collection' collects transportation-related data from other centers, performs data quality checks on the collected data and then consolidates, verifies, and refines the data and makes it available in a consistent format to applications that support operational data sharing between centers and deliver traveler information to end-users. A broad range of data is collected including traffic and road conditions, transit data, emergency information and advisories, weather data, special event information, traveler services, parking, multimodal data, and toll/pricing data. It also shares data with other transportation information centers. Transportation Information Center
TIC Traffic Regulation Dissemination 'TIC Traffic Regulation Dissemination' disseminates rules, regulations, and statutes that govern motor vehicle operation. It aggregates regulations from regulatory authorities and then disseminates the relevant regulations to vehicles and other mobile devices. Transportation Information Center
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 Traveler Information Reception 'Vehicle Traveler Information Reception' provides the capability for drivers to receive general transportation information including traffic and road conditions, traffic regulations, incident information, maintenance and construction information, event information, transit information, parking information, weather information, and broadcast alerts.

Regulations should be publicly accessible, so observation of this flow gains no information that could not be obtained legitimately. Regulations may be used to guide operations, particularly for automated vehicles. As such, inaccurate regulations imply the vehicle operator (human or otherwise) may inadvertently violate regulations, possibly endangering the safety of others expecting the operator or vehicle to follow the rules of the road. Regulations will be used to guide the operator, which may be an autonomous vehicle. As such the regulations need to be kept up to date to avoid conflict with regulations, penalties or of course safety of life. Availability is not considered HIGH as it is unlikely that such regulations that affect safety would change very often. In environments where it is envisioned that safety-impacting regulations change quickly, HIGH would be justified.

Traveler Personal Information Device traveler input Not Applicable Moderate Low
This data is informing the vehicle of operational information that is relevant to the operation of the vehicle. It should not contain anything sensitive, and does not matter if another person can observe it. While public, information must be correct or travelers may make incorrect decisions with regard to their travel plans. Information is available through other means, though depending on the location this might not always be the case, in which case this would be MODERATE.
Vehicle OBE 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.
