Weather-Related VII Use Cases

TimelineTimeline

January 28 - February 9 – Developed Draft Use Cases February 10 – Meeting at BAH facility in Arlington February 13-17 – Revise use cases February 22 & 23 - Workshop in Boulder, Colorado at NCAR February 27 – Revise Draft Use Cases based on Boulder

Workshop March 9 - Weather VII Use Case Kick-off Telecon March 24 – Clarus Task Force Comments Due March 27 – Meeting at US DOT to disposition Clarus Task

Force Comments March 28 - Weather VII Use Case Wrap-Up Telecon March 28-31 – Revise use cases March 31 – Received more AASHTO comments April 5 – Sent out revised weather-related use cases

Comment SummaryComment Summary

Traveler Notification with Clarus:  17 commenters, ~200 comments

Traveler Notification without Clarus:  15 commenters, ~100 comments

Improved Weather Observing and Forecasting: 17 commenters, ~150 comments

Winter Maintenance:  16 commenters,  ~100 comments Pothole Maintenance:  13 commenters, ~80 comments Many of the comments to one use case also applied to the

others The number of comments is indicative of the complexity of

creating a concept of operations between 2 US DOT research initiatives, Clarus and VII

Primary ChangesPrimary Changes

Extended NOAA actor to include the Weather Enterprise

Expanded Weather Data Translator (WDT) Concept

Current StatusCurrent Status

Merged/Aligned all Use Cases into one Model Slight renaming of actors and use cases Drill-down within each use case – layered model Allocate actors and use cases to services Developing VII Network Services Creating VII Concept of Operations Creating VII System Requirements Specification VII System Security Plan out for review
