Includes Physical Objects:

Physical Object Class Description
Commercial Vehicle Driver Vehicle The 'Commercial Vehicle Driver' represents the people that operate vehicles transporting goods, including both long haul trucks and local pick-up and delivery vans. This physical object is complementary to the Driver physical object in that it represents those interactions which are unique to Commercial Vehicle Operations. Information flowing from the Commercial Vehicle Driver includes those system inputs specific to Commercial Vehicle Operations.
Commercial Vehicle OBE Vehicle The Commercial Vehicle On-Board Equipment (OBE) resides in a commercial vehicle and provides the sensory, processing, storage, and communications functions necessary to support safe and efficient commercial vehicle operations. It provides two-way communications between the commercial vehicle drivers, their fleet managers, attached freight equipment, and roadside officials. A separate 'Vehicle OBE' physical object supports vehicle safety and driver information capabilities that apply to all vehicles, including commercial vehicles. The Commercial Vehicle OBE supplements these general ITS capabilities with capabilities that are specific to commercial vehicles.
Fleet and Freight Management Center Center The 'Fleet and Freight Management Center' provides the capability for commercial drivers and fleet-freight managers to receive real-time routing information and access databases containing vehicle and/or freight equipment locations as well as carrier, vehicle, freight equipment and driver information. The 'Fleet and Freight Management Center' also provides the capability for fleet managers to monitor the safety and security of their commercial vehicle drivers and fleet.
Fleet-Freight Manager Center The 'Fleet-Freight Manager' represents the people that are responsible for the dispatching and management of Commercial Vehicle fleets (e.g. traditional Fleet Managers) and Freight Equipment assets. It may be many people in a large tracking organization or a single person (owner driver) in the case of single vehicle fleets. The Fleet-Freight Manager provides instructions and coordination for Commercial Vehicles and Freight Equipment and receives the status of the vehicles and freight equipment in the fleet that they manage.
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.
Parking Area Equipment Field 'Parking Area Equipment' provides electronic monitoring and management of parking facilities. It supports an I2V link to the Vehicle that allows electronic collection of parking fees and monitors and controls parking meters that support conventional parking fee collection. It also includes the instrumentation, signs, and other infrastructure that monitors parking lot usage and provides local information about parking availability and other general parking information. The two primary approaches to monitoring parking area usage are sensing vehicles within parking spots or counting vehicles as they come in and as they leave the area. This portion of the functionality must be located in the parking area where it can monitor, classify, and share information with customers and their vehicles. See also the separate 'Parking Management Center' physical object that may be located in a back office, remote from the parking area, which interfaces with the financial infrastructure and broadly disseminates parking information to other operational centers in the region.
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.
Parking Operator Field 'Parking Operator' is the human attendant that may be physically present at the parking lot facility to monitor the operational status of the facility.
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.
