The purpose of this study was to evaluate motorist information needs during adverse winter travel conditions, and the application of this information to changeable message signs. Local commuters and interstate truck traffic along Interstate 80 in southeast Wyoming were the principle source of information. Laboratory studies, field surveys and supplemental surveys were used for the collection of data.

Specific objectives of this research were to identify and separate user groups within the study population; to identify information need consistencies within user groups for particular adverse winter travel conditions; to determine the priority of winter travel information needs; and to develop changeable sign messages to be displayed for different adverse weather travel conditions.
