Abstract: In order to explore the driving anger inducement of bus drivers,a driving anger scale for bus drivers was designed through interview,on the basis of the original driving anger scale and driving anger scale for coach drivers.210 valid copies of questionnaire were obtained in Guangdong province.A finalized version of the scale was achieved through the project analysis,exploratory factor analysis,reliability and validity tests.Besides,Pearson correlation analysis and independent sample t-test were conducted to make a preliminary analysis of the result.The analysis result reveals that the revised driving anger scale,which contains 5 subscales: self-interested behaviors,slow driving,traffic obstructions,illegal driving and discourtesy,is made up of 23 items and demonstrates great reliability and validity,that among the 5 subscales,the average score of self-interested behaviors is the highest,that bus drivers involved in at least one accident and punished for breaking traffic laws in the past two years both significantly scored higher in slow driving,that bus driving age is positively correlated with the scores of all subscales,except slow driving,and that while average working hours per day is positively correlated with the scores of both self-interested behaviors and discourtesy.

Key words: bus drivers, driving anger scale, driving behavior, traffic safety, reliability, validity
