| Abstract | Adverse weather conditions have been shown to have a substantial impact on traffic flow operations. It is however unclear which adaptation effects in actual longitudinal driving behavior underlie this impact nor to what extent current mathematical models of carfollowing behavior are adequate in incorporating these adaptation effects. A driving simulator experiment with a repeated measures design was performed to investigate the influence of fog on adaptation effects in longitudinal driving behavior as well as to gain insight into parameter value changes and model performance of the Helly model and the Intelligent Driver Model under this adverse weather condition. From the results it followed that fog led to substantial adaptation effects in longitudinal driving behavior. A decrease in speed as well as in acceleration could be observed. Furthermore, a substantial increase in actual distance to the lead vehicle was observed. From the model estimation results of the Helly model and Intelligent Driver Model using a calibration approach for joint estimation it followed that sensitivity factors, maximum acceleration and deceleration decreased substantially after the start of the adverse weather condition. Parameters representing headway increased substantially. Furthermore, it followed from the results that the estimated models decreased in performance after the start of the adverse weather condition. It is concluded that it is essential to develop car-following models able to adequately incorporate these adaptation effects following adverse weather conditions. |
