Based on fuzzy evaluation matrices of driver's road safety perception,calculation of the membership of safety perception has to pass though a series of transformation from the bottom index membership.According to excavating the information of the object classification that hides in index memberships,the divisional right was defined by using data excavation method based on entropy.The redundant index memberships that were useless for classification were deleted by using divisional weight and effective values in index memberships that were useful for classification were extracted.Then the effective values were transformed to comparable values to generate comparable sum.At last the object membership was calculated by sum of comparable values.Based on this,a general algorithm for realizing the membership transformation was realized for the synthesis evaluation of driver's road safety.
