corridor operational strategies Quintuple

Bidirectional?: False

corridor operational strategies (A-Interconnect): This CVRIA application interconnect encapsulates all of the Layer 2 information flows between two application objects: 'TIC Corridor Decision Support System', and 'TMC Regional Traffic Management'. In this case, there is only a single Layer 2 flow associated with this interconnect, so the Layer 1 application interconnect name and the Layer 2 information flow name are both 'corridor operational strategies'. This application interconnect is uni-directional since the underlying layer 2 information flows go from 'Transportation Information Center' to 'Traffic Management Center'.

Transportation Information Center (Source Physical Object): 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.

TIC Corridor Decision Support System (Source Application Object): The "TIC Corridor Decision Support System" is a data-fusion system that collects information from various multimodal systems. Data from these systems is then used to determine operational strategies for arterials, freeways, and transit that minimize the environmental impact of the corridor. It may recommend eco-signal timing plans, eco-ramp metering strategies, eco-speed limits, and recommendations for increased transit service.

Traffic Management Center (Destination Physical Object): 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.

TMC Regional Traffic Management (Destination Application Object): "TMC Regional Traffic Management" supports coordination between traffic management centers in order to share traffic information between centers as well as control of traffic management field equipment. This coordination supports wide area optimization and regional coordination that spans jurisdictional boundaries; for example, coordinated signal control in a metropolitan area or coordination between freeway operations and arterial signal control within a corridor.
