| 摘要： | 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. For the first objective, a survey was developed by the UTL and the Project's Technical Advisory Committee to determine what people want in terms of the type, amount, and preferred delivery method of weather related road information. The surveys indicate that road condition information is preferred by all groups over information on alternate routes, travel times, and travel speeds. They also indicate that road conditions which alter driving habits, such as accumulating snow, fog, ice, wind, and road closures, are most important while rain, non-sticking snow, thunder storms, and snow flurries are less important. The third objective relates to how an RWIS site's information changes with increasing distance from the sensor location. |
