摘要：	Weather causes a variety of impacts on the transportation system. While severe winter storms, hurricanes, or flooding can result in major stoppages or evacuations of transportation systems and cost millions of dollars, day-to-day weather events such as rain, fog, snow, and freezing rain can have a serious impact on the mobility and safety of the transportation system users. These weather events can result in increased fuel consumption, delay, number of accidents, and significantly impact the performance of the transportation system. The overall goal of the research work undertaken in this study was to develop a better understanding of the impacts of weather on traffic flow. The research was intended to accomplish the following specific objectives: (1) Study the impact of precipitation on macroscopic traffic flow parameters over a full range of traffic states; (2) Study the impact of precipitation on macroscopic traffic flow parameters using consistent, continuous weather variables; (3) Study the impact of precipitation on macroscopic traffic flow parameters on a wide range of facilities; (4) Study regional differences in reaction to precipitation; and (5) Study macroscopic impacts of reduced visibility. / Supplementary Notes: Sponsored by Virginia Dept. of Transportation, Richmond., Federal Highway Administration, Richmond, VA.
