Driving Simulator Validation Study Under Car-following Condition

Abstract:

In order to verify the validation of car-following behavior study based on driving simulation, the natural driving experiment and driving simulation experiment were designed. The driver’s delay time, car-following distance and its standard deviation were selected as analysis index. The validity of non-time data and time data were verified by Wilcox test and survival analysis method respectively. The result indicates that car-following distance and driver’s delay time have absolute validity. The standard deviation of car-following distance has the same change trend in two different experimental environments, which means it has relative validity. In the natural driving experiment acceleration of the following vehicle, relative distance, and acceleration change status of the following vehicle effect driver’s delay time significantly. The result of validation study provides precondition for other driving-simulation-based car-following behavior research. Survival analysis result can be used for driver’s delay time modeling and car-following model optimization.
