Abstract: In order to assess the applicability of the SCQ-MD (Safety Climate Questionnaire, Modified for Drivers) scale in measuring the safety climate perception of airport drivers, the questionnaire survey and SPSS 22.0 statistical analysis method were used to study the statistical data of safety climate perception of airport drivers. The research results show that the correlation between the items and the total scores of the SCQ-MD scale has reached significant level, with good item discrimination. Six factors obtained by exploratory factor analysis accounts for 72.124% of the variance variation, which has good structural validity. There is a correlation between the four demographic variables of subjects and the perception of safety climate of airport drivers, which is consistent with previous research results and has good criterion validity. And the four demographic variables include age, driving age, regional distribution and working time in the airport of the tested. Cronbachα coefficient of the proposed SCQ-MD is 0.987, and the Cronbach α coefficient of each factor is greater than 0.9, indicating that the proposed scale has good reliability. The DBQ scale is introduced to empirically analyze the relationship between safety climate and drivers unsafe behavior, and finds that there is a significant negative correlation between the two. The SCQ-MD scale has good reliability and validity, and it is consistent with the previous research conclusions in the application analysis results, which indicates that the proposed scale is suitable for measuring the perception of the safe atmosphere of the airport drivers.
