WEATHER: IT AFFECTS THE VISIBILITY, TRACTABILITY, MANEUVERABILITY, VEHICLE STABILITY, EXHAUST EMISSIONS AND STRUCTURAL INTEGRITY OF THE SURFACE TRANSPORTATION SYSTEM. THEREBY WEATHER AFFECTS THE SAFETY, MOBILITY, PRODUCTIVITY AND ENVIRONMENTAL IMPACT OF THAT SYSTEM. THE WEATHER CANNOT BE CONTROLLED SIGNIFICANTLY, BUT ALL TRANSPORTATION DECISION MAKERS NEED INFORMATION ABOUT THE WEATHER TO TREAT AND COPE WITH ITS EFFECTS. THE FEDERAL HIGHWAY ADMINISTRATION (FHWA) OF THE U.S. DEPARTMENT OF TRANSPORTATION (USDOT) HAS A RESPONSIBILITY TO COORDINATE AND PROMOTE PROJECTS THAT WILL BRING THE BEST INFORMATION ON WEATHER TO DECISION MAKERS, IN ORDER TO IMPROVE PERFORMANCE OF THE SURFACE TRANSPORTATION SYSTEM.
TO FULFILL ITS RESPONSIBILITY, THE FHWA'S OFFICE OF TRANSPORTATION OPERATIONS (HOTO) WEATHER AND WINTER MOBILITY PROGRAM IS DOCUMENTING THE WEATHER INFORMATION REQUIREMENTS OF ALL ROAD USERS AND OPERATORS UNDER THIS SURFACE TRANSPORTATION WEATHER DECISION SUPPORT REQUIREMENTS (STWDSR) PROJECT. THE STWDSR PROJECT IS BEING CONDUCTED FOR THE FHWA BY MITRETEK SYSTEMS, INC.
