This Preliminary Interface Requirements (PIR) is a draft document for the Surface Transportation Weather Decision Support Requirements (STWDSR) project. The STWDSR project is being conducted by Mitretek Systems, Inc., for the Federal Highway Administration (FHWA) Office of Transportation Operations (HOTO) Road Weather Management Program. The PIR complements the STWDSR Operational Concept Description (OCD) document, and both documents together constitute the STWDSR version 2.0 (V2.0) deliverable. The PIR defines requirements on the external information sources for the winter road maintenance decision support functions described in the OCD. |
