Cause analysis of highway traffic accidents based on the 24Model
In order to reduce the occurrence rate of highway traffic accidents,the causation of three major traffic accidents on a highway in Guangdong Province and two major traffic accidents on a highway in Shandong Province are analyzed using the 24Model.The causation chain of traffic accidents is established from the perspectives of unsafe actions,physical and safety capabilities at the individual level,and the safety management system and safety culture at the organizational level.The results show that the direct causes of the accidents include failure to take necessary deceleration measures to control the speed,failure to maintain a reasonable distance from the preceding vehicle,failure to control vehicle speed due to long downhill sections,failure to handle overloaded vehicles in accordance with regulations,poor visibility during night driving,slippery roads in rainy weather,and lack of road-side guiding warning devices.The indirect causes of the accidents include a lack of safety knowledge and awareness among drivers and management personnel.The root causes of the accidents include ineffective enforcement of traffic safety regulations and the need for improvement in the"one road,three parties"system.The fundamental cause of the accidents is the lack of a perfect traffic safety culture.
