• Abstract:
  With the economic booming development of coastal areas, the importance of the traffic planning becomes ; obvious not only in a hurricane evacuation but also in the daily transportation. Vehicle performance on the ; freeway during harsh environments is critical to the success of the planning process. The present study aims ; to study the effect of harsh environments on the driving behavior and vehicle performance. The driving ; simulator installed in Louisiana State University was used to investigate the driver’s behavior and vehicle ; performance in different adverse conditions such as strong crosswinds, wet road surface, and curving. ; Modified parameters of the driving simulator were determined to reproduce the real wind loadings ; according to the vehicle velocity and wind velocity, through the manipulation of appropriate software. ; While the vehicle performance was recorded in terms of lane offset, vehicle velocity, and heading error, the ; driver’s reaction was measured in the form of the reaction time, steering angle, and the time of pressing on ; brake and gas pedal, respectively. The results illustrate that a higher wind speed leads to more variance of ; lane offset and heading error. The rainy weather/wet road surface does have an effect on the vehicle ; velocity in a strong wind environment. The findings of this study demonstrate the valuable use of a driving ; simulator to represent different hazardous driving conditions and to develop a statistic model to predict and ; estimate the driver’s behavior and vehicle performance.
