Abstract
The main objective of this study is to investigate and determine the share of the three factors of human, vehicle and road in crashes in Isfahan province. For this purpose, the causes of crashes and the causes of injuries resulting from crashes that lead to injury or death of drivers and passengers have been studied and the share of the three factors in this case have been calculated. Also, in this study, the difference between the nature before and during the crash (from the Haddon matrix) has been examined; that the share of human factor in 97.5 percent, road factor in 36.9 percent and vehicle factor in 8.9 percent of crashes (cause of crashes) in Isfahan province play a role; also, in-depth analyses showed that human factors such as lack of attention to the front, high speed and a set of inappropriate behaviors of drivers account for more than 85 percent of all crashes and if these factors are eliminated, we expect that 85 percent of crashes will not occur; also, in general, by eliminating each of the factors affecting the crash, it is expected that no crash will occur. In the following, the share of vehicle, human and road factors in injuries during the crash were calculated to be 83.4, 45.2 and 30.6 percent, respectively, which shows that vehicles play the most role in injuring drivers and passengers of vehicles during the crash and if each of these factors are eliminated in crashes, we expect that the severity of the crash will decrease. Due to the lack of volume of the database, in the future, the use of more sources, including insurance and repair shop reports, is suggested for more accurate analysis of the share of factors.
