Abstract: Driving behaviors under anger emotion are one of the most important factors impacting on traffic safety . Drivers and road traffic environment affect the degree of driver's anger directly .This research proposes a hierarchical anal‐ysis model to identify the angry driving behaviors ,which is based on the factors ,resulted in angry driving related to driv‐er's individual factors and the road environment factors .According to the importance of related factors to driver's behav‐iors ,the hierarchical analysis model creates a judgment matrix ,and calculates the effect weight from the related factors to angry driving .The angry driving behaviors and the extent of anger are identified by using the comprehensive weighting method of matter‐element multi‐attribute decision .A total of 22 on‐road experiments on urban road were conducted to ac‐quire the data of angry driving behaviors .72 .7 angry driving behaviors were identified by using the proposed model .The results also show that the proposed model l can identify the angry driving behaviors and the extent of anger effectively , based on the individual driver's factors and the road environment .
