Selected Model and Sensitivity Analysis of Aggressive Driving Behavior

Taking 160 drivers as the research object,the influence factors of their aggressive driving behavior were analyzed through the theory of behavior and modeling method of disaggregate discrete choice.In the research,the authors determined variables for the influence factors of aggressive driving behavior choice and the ways to obtain their values,and developed a multinomial Logit(MNL) model.The influence degree and process to aggressive driving behavior were analyzed by elasticity theory.Another 58 drivers behavior data were selected to testify the model's validity.The result shows that the personality of the drivers and violation of other vehicle are the crucial factors to aggressive driving behavior,with the relative error of 10% between judgment data of scale and computational values by MNL,therefore the model accuracy can meet the actual requirements.
