• Data derived from the questionnaires, interviews, and surveys provides foundation to build WIST needs and requirements

• This data-set forms a nucleus from which both public and private weather providers can:– Refine existing capabilities– Improve capabilities and services– Identify and leverage research and development proposals – Implement new initiatives for surface transportation weather

information heretofore not addressed– Identify weather information needs and weather products
