Link Type: Center to Center
qualified environmental conditions data (Information Flow): Current road conditions (e.g., surface temperature, subsurface temperature, moisture, icing, treatment status) and surface weather conditions (e.g., air temperature, wind speed, precipitation, visibility) that has had quality checks performed on it and has been formatted and consolidated by the Clarus system. Attributes relating to the data collection (and aggregation) are also included.
Weather Service System (Source Physical Object): The 'Weather Service System' provides weather, hydrologic, and climate information and warnings of hazardous weather including thunderstorms, flooding, hurricanes, tornadoes, winter weather, tsunamis, and climate events. It provides atmospheric weather observations and forecasts that are collected and derived by the National Weather Service, private sector providers, and various research organizations. The interface provides formatted weather data products suitable for on-line processing and integration with other ITS data products as well as Doppler radar images, satellite images, severe storm warnings, and other products that are formatted for presentation to various ITS users.
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.

This Triple is in the following Functional Objects:
This Triple is described by the following Functional View Data Flows:
This Triple has the following triple relationships:
|Depends On||Traffic Management Center||Weather Service System||environmental conditions data|
Communication SolutionsNo communications solutions identified.
|National||This triple should be implemented consistently within the geopolitical region through which movement is essentially free (e.g., the United States, the European Union).|
|Information Flow Security|
|Basis||If this data were exposed there would be little to no harm, except that the exposure was not authorized and the sender had no knowledge of downstream data usage. That alone is difficult to judge as 'serious harm' so left at LOW.||Since the point of this particular flow is to provide data that is already quality checked, corruption of this data would have a significant negative impact on the users of this data.||This flow is used to help determine what road operations actions should be taken. If unavailable then other mechanisms would be used, but these would degrade the overall quality of road condition estimation; if that estimate fails to suggest the correct actions, the cost to mobility could be significant.|
