Analysis of Accident Factors and Consideration of Risk Assessment Method Based on Results of Tractor Accident Survey

Abstract

For the purpose of safety, it is important to prevent tractor accidents, which are the most common fatal agricultural machine accidents. In this study, the probability of a tractor accident and the severity of injury were quantified from the results of a tractor accident survey. The risk of each accident cases and the factors involved were quantified based on the probability and the severity of injury. The results show that the risk of death and serious injury can be reduced by approximately 57 % and 61 %, respectively. Furthermore, the risk of an accident is expected to be lower than the threshold of death and serious injury by addressing three factors: unsafe and poor machine operability, road inclination, and narrow roads.
