In order to improve dynamoelectric efficiency of the wind power dynamo and to analyze the wind direction track manipulative system,this system adopts the initiative to windward mode,the wind direction measured by vane,then the system determining the adjustive direction according to the angle between wind direction and impeller plane normal direction.

Based on critical acceleration andits physiological and psychological characteristics on driver,this paper advances a model to calculate car-following riskindex andlane-changing riskindex.
