Safety Risk Assessment Model of Heavy-Haul Transport

Abstract

In order to evaluate the safety situation of heavy-haul transport accurately, the model to assess the risk grade of heavy-haul transport is established based on the theory of risk matrix and G1 method. First, the paper constructs the risk assessment index system, which consists of 28 risk factors involved four types of personnel, equipment, environment, and management. Second, the risk factors are sorted by Borda value method, and the key risk factors are found out according to the Borda sequence value, which can help managers to take targeted measures. Finally, the model is employed in the safety assessment of heavy-haul transport of Datong–Baotou railway. The results show that its safety risk grade is in secondary grade. The top three risk factors are the reliability of power system, the damage of water disaster and the rescue equipment. And the result is consistent with the actual. It shows that the risk matrix method is feasible for the safety risk assessment and the proposed model can assess the safety risk of heavy-haul transport objectively.
