Abstract:This is a draft document for the Surface Transportation Weather Decision Support Requirements
(STWDSR) project. The STWDSR project is being conducted for the FHWA’s Office of
Transportation Operations (HOTO) Road Weather Management Program by Mitretek Systems,
Inc. The STWDSR V1.0 document was delivered in January, 2000, and gave background on the
program and an initial needs analysis for decision support to winter road maintenance. Since
then, two stakeholder meetings have refined the needs analysis and reviewed the initial
operational concept for the Weather Information for Surface Transportation Decision Support
System (WIST-DSS). The WIST-DSS is the conceptual system on which the STWDSR are levied, and the operation of which is described in this Operational Concept Description (OCD).
The STWDSR V1.0 should be referred to for full project background, that will be summarized in
this introduction. The STWDSR through V2.0 is focusing on decision support requirements for
winter road maintenance managers. Needs have been defined for all surface transportation
decision makers and later phases of the project will develop their decision support requirements more fully. Therefore the WIST-DSS and its OCD should be considered expandable in user scope. The STWDSR project has two primary objectives:
• To provide requirements, at a high level, that can be allocated to lower levels, within a
spiral evolutionary process of WIST-DSS deployment.
• To identify requirements on external information resources for the WIST-DSS that can be
addressed by programs within the FHWA and by inter-agency programs with the
meteorological community and others.
