Surface Transportation Weather Service --> Traffic Management Center:
transportation weather information
Definitions
transportation weather information (Information Flow): Current and forecast road conditions and weather information (e.g., surface condition, flooding, wind advisories, visibility, etc.) associated with the transportation network. This information is of a resolution, timeliness, and accuracy to be useful in transportation decision making.
Surface Transportation Weather Service (Source Physical Object): The 'Surface Transportation Weather Service' represents the providers of value-added sector-specific meteorological services. These providers utilize National Weather Service data and predictions, road condition information and local environmental data provided by traffic management or maintenance organizations, and their own models to provide surface transportation related weather observations and forecasts including pavement temperature and conditions.
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.

Interoperability | Description |
---|---|
Regional | Interoperability throughout the geopolitical region is highly desirable, but if implemented differently in different transportation management jurisdictions, significant benefits will still accrue in each jurisdiction. Regardless, this Information Flow Triple should be implemented consistently within a transportation jurisdiction (i.e., the scope of a regional architecture). |

Basis | Typically intended for public distribution. | While there are many sources of weather information, some guarantee of correctness is justifiable to keep confidence in provided service. In areas with severe weather it may be justifiable to raise this to HIGH. | There should be other sources of this data. It does need to be reliable however; weather can change quickly, and depending on the destination and its operational strategies, timely response may be important. In areas with severe weather it may be justifiable to raise this to HIGH. |
