ARROWS Evaluation

In a June 2002 meeting, winter maintenance managers at the Washington State Department of
Transportation (WSDOT) said that more accurate forecasts, that told not only where but when inclement
weather was due, would be a valuable tool to aid them in keeping Washington State highways safe and
passable during winter months. In response, the WSDOT ITS Office teamed with the University of
Washington Department of Atmospheric Sciences to build weather information and forecasting Web
pages specifically tailored to the managers' desires and needs.

The result was the development of the ARROWS (Automated Real-time Road Weather System)
Web pages, made available to all WSDOT winter maintenance managers for the 2003-2004 winter
season. WSDOT subsequently conducted an inhouse survey to determine what ARROWS users thought
about the usefulness and presentation of information. This report presents the results of that survey,
which have been used as input to the continuing development of ARROWS.
