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.
