外文摘要：The main objective of this study is to investigate the impact of adverse weather on traffic stream behavior by calibrating key traffic flow parameters on Interstate 80 (1-80) in Wyoming。 In order to achieve the study objectives， data from four field sensors and nearby road weather information system (RWIS) were collected from the Wyoming Department of Transportation (WYDOT) and utilized to calibrate key traffic stream parameters。 Calibrated the Highway Capacity Manual (HCM) models in different road surface conditions were fitted using the field sensor data。 Most of the traffic flow parameters were found to be well-fitted。 It was also observed that the percentage of heavy trucks on 1-80， Wyoming， is extremely high， especially in adverse weather compared to clear weather conditions。 The calibration procedure conducted in this study provided valuable insights regarding the key macroscopic traffic parameters considering adverse weather conditions。
