driver information Quintuple

Bidirectional?: False

driver information (A-Interconnect): This CVRIA application interconnect encapsulates all of the Layer 2 information flows between the 'Roadway Traffic Information Dissemination' application object and the 'Transit Vehicle Operator' physical object. 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 'driver information'. This application interconnect is uni-directional since the underlying layer 2 information flows go from 'ITS Roadway Equipment' to 'Transit Vehicle Operator'.

ITS Roadway Equipment (Source Physical Object): '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 itself. In CVRIA, this physical object represents all of the other ITS field equipment that interfaces with and supports the Connected Vehicle Roadside Equipment (RSE). 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.

Roadway Traffic Information Dissemination (Source Application Object): "Roadway Traffic Information Dissemination" includes field elements that provide information to drivers, including dynamic message signs and highway advisory radios.

Transit Vehicle Operator (Destination Physical Object): The 'Transit Vehicle Operator' represents the person that receives and provides additional information that is specific to operating the ITS functions in all types of transit vehicles. The information received by the operator would include status of on-board systems. Additional information received depends upon the type of transit vehicle. In the case of fixed route transit vehicles, the Transit Vehicle Operator would receive operator instructions that might include actions to take to correct schedule deviations. In the case of flexible fixed routes and demand response routes the information would also include dynamic routing or passenger pickup information.
