transit system data Quintuple

Bidirectional?: False

transit system data (A-Interconnect): This CVRIA application interconnect encapsulates all of the Layer 2 information flows between two application objects: 'Transit Center Multi-Modal Coordination', and 'TMC Multi-Modal Coordination'. 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 'transit system data'. This application interconnect is uni-directional since the underlying layer 2 information flows go from 'Transit Management Center' to 'Traffic Management Center'.

Transit Management Center (Source Physical Object): 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 allow for communication between transit departments and with other operating entities such as emergency response services and traffic management systems.

Transit Center Multi-Modal Coordination (Source Application Object): "Transit Center Multi-Modal Coordination" supports transit service coordination between transit properties and coordinates with other surface and air transportation modes. As part of service coordination, it shares schedule and trip information, as well as transit transfer cluster (a collection of stop points, stations, or terminals where transfers can be made conveniently) and transfer point information between Multimodal Transportation Service Providers, Transit Agencies, and ISPs. An interface to Traffic Management also supports demand management strategies.

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 Multi-Modal Coordination (Destination Application Object): "TMC Multi-Modal Coordination" supports center-to-center coordination between the Traffic Management and Transit Management Centers. It monitors transit operations and provides traffic signal priority for transit vehicles on request from the Transit Management Center.
