This research document represents the analysis and recommendations of the University of Utah Traffic Laboratory (UTL) on the following Road Weather Information System (RWIS) topics: 1. public dissemination of RWIS station information, and 2. the area of influence of available RWIS equipment. A survey was developed, targeted to commuters, truckers, recreational travelers, and long distance travelers - to discern what users want regarding the type, amount, and preferred delivery method of weather related road information. Results of the survey indicate that variable message signs and radio are the most popular form of RWIS information dissemination. The most desired subject matter for information was road condition. This is preferred by all groups over information on alternate routes, travel times and travel speeds. Road conditions which change driving habits, such as accumulating snow, ice, fog, wind, and road closures are the most important. Rain, non-sticking snow, thunder storms, and snow flurries are less important. All equipment vendors will only "guarantee" the RWIS information in the immediate vicinity of the sensors.
