Abstract：In order to improve the safety of road transportation of flammable and explosive materials,considering the impact of road characteristics,traffic conditions,and weather conditions on traffic accidents,the correction coefficient of traffic accident influencing factors is determined,and the probability of flammable and explosive material leakage caused by traffic accidents is calculated.At the same time,the probability of flammable and explosive material leakage caused by non-traffic accidents is considered,and the probability of flammable and explosive material road transportation leakage accidents is obtained by combining the two.The road transportation risk is subdivided into personnel injury risk,environmental damage risk,and property loss risk,and the three types of risk losses are quantitatively calculated to construct a flammable and explosive material road transportation path optimization model with the goal of minimum transportation risk,transportation cost,and transportation distance.Taking some road networks in Shandong Province as an example,the Dijkstra algorithm and the extended labeling method based on fuzzy compromise programming are used to solve the multi-objective road transportation path optimization model for flammable and explosive materials.The results show that the transportation risk,transportation cost,and transportation distance of the three optimal routes calculated are small.Compared with the shortest transportation distance route and the minimum transportation cost route,the transportation risk of the optimized route is greatly reduced,and the transportation cost and distance are slightly increased.
