Vehicle Operations and Service Center --> Traffic Management Center:
vehicle situation data

Definitions

vehicle situation data (Information Flow): This flow represents vehicle snapshots that may be provided by the vehicle to support traffic and environmental conditions monitoring. Snapshots are collected by the vehicle for specific events (e.g., when a sensor exceeds a threshold) or periodically and reported based on control parameters when communications is available. Traffic-related data includes snapshots of measured speed and heading and events including starts and stops, speed changes, and other vehicle control events. Environmental data may include measured air temperature, exterior light status, wiper status, sun sensor status, rain sensor status, traction control status, anti-lock brake status, and other collected vehicle system status and sensor information. The collected data is reported along with the location, heading, and time that the data was collected.

Vehicle Operations and Service Center (Source Physical Object): 'Vehicle Operations and Service Center' (VOSC) represents centers that provide telematics services to vehicles using wide-area (e.g. cellular) communications, including traveler information, emergency services, vehicle diagnostics, over-the-air software updates, vehicle maintenance information and warnings, remote vehicle operation, and provision of service options for these vehicles. See also 'Transportation Information Center' that provides traveler information, trip planning, and routing services and 'Emergency Management Center' that provides call-taking and emergency response services that may also be implemented by a VOSC.

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.

    Basis Might be able to link multiple snapshots together and compromise some element of driver/traveler privacy. Event driven data can be used for various mobility monitoring applications, and as operational decisions may be made based on mobility conditions, this data's accuracy should be preserved or decisions may not align with real situations. While desireable, in most application contexts the provision of a single vehicle's data through this flow is not critical.
