transit vehicle emissions Quintuple

Bidirectional?: False

transit vehicle emissions (A-Interconnect): This CVRIA application interconnect encapsulates all of the Layer 2 information flows between two application objects: 'Transit Vehicle Emissions Monitoring', and 'Transit Center Emissions Monitoring'. 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 vehicle emissions'. This application interconnect is uni-directional since the underlying layer 2 information flows go from 'Transit Vehicle OBE' to 'Transit Management Center'.

Transit Vehicle OBE (Source Physical Object): The Transit Vehicle On-Board equipment (OBE) resides in a transit vehicle and provides the sensory, processing, storage, and communications functions necessary to support safe and efficient movement of passengers. The types of transit vehicles containing this physical object include buses, paratransit vehicles, light rail vehicles, other vehicles designed to carry passengers, and supervisory vehicles. It collects ridership levels and supports electronic fare collection. It supports a traffic signal prioritization function that communicates with the roadside physical object to improve on-schedule performance. Automated vehicle location enhances the information available to the transit operator enabling more efficient operations. On-board sensors support transit vehicle maintenance. The physical object supports on-board security and safety monitoring. This monitoring includes transit user or vehicle operator activated alarms (silent or audible), as well as surveillance and sensor equipment. The surveillance equipment includes video (e.g. CCTV cameras), audio systems and/or event recorder systems. It also furnishes travelers with real-time travel information, continuously updated schedules, transfer options, routes, and fares. In CVRIA, a separate 'Vehicle OBE' physical object supports the general V2V and V2I safety applications and other applications that apply to all vehicles, including transit vehicles. The Transit Vehicle OBE supplements these general capabilities with capabilities that are specific to transit vehicles.

Transit Vehicle Emissions Monitoring (Source Application Object): "Transit Vehicle Emissions Monitoring" directly measures or estimates vehicle emissions and provides current and average emissions measures to the Transit Management Center.

Transit Management Center (Destination 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 Emissions Monitoring (Destination Application Object): "Transit Center Emissions Monitoring" collects and/or estimates current transit fleet emissions and forecasts future fleet emissions. The collected, estimated, and forecast emissions is monitored and forwarded to other agencies to more effectively manage transit operations to reduce emissions.
