Research On The Cost Measurement And Control Of Dangerous Goods Road Transportation

With the development of China’s industry,the dangerous goods market has shown a growing trend,but in sharp contrast to the ever-expanding market size,the facilities,systems and other aspects of dangerous good industry are imperfect,which led to rising dangerous goods accident rate in recent years,has brought great risks to the life and property and environmental security.The reasons for these problems are multifaceted.Due to the particularity of dangerous goods and the convenience of road transport,the proportion of dangerous goods transported by road has been increasing year by year,and the accident rate,which poses a great threat to the people around the road transportation line.To a certain extent,transport risk is actually part of the cost of transport,and rising risk costs also challenge the development of the transport of dangerous goods.Therefore,in this study,the risk cost of transportation risk is expounded as part of the transportation cost,and the risk of transportation is analyzed in economic way.First,the main factors influencing the risk of dangerous road transportation cost are analyzed,such as the population density.The main risk factors are taken into the risk cost measurement model,the model of dangerous goods road transport cost is established.And the influence degree of the same risk factor,population density,traffic free flow velocity and traffic density,are analyzed and three basic conclusions are drawn.(1)The form that the vehicle distance should be not less than 50 meters on China’s highway has been verified by the conclusions of this study.The cost of transport of dangerous goods under this vehicle distance is the lowest,which is the best traffic density.When the traffic density is less than the optimal traffic density,the impact force of the vehicle is large and the risk of dangerous goods is large.When the traffic density is greater than the optimum traffic density,the number of people exposed to the risk of leakage of dangerous goods increases the risk of high personnel risk.(2)When the population density is small,the free flow velocity has a great influence on the risk cost,and when the population density is large,the impact of the free flow velocity on the risk cost is relatively weak.(3)When the free flow velocity is small,the population density is less effective than the risk cost.When the free flow velocity is large,the population density is positively correlated with the risk cost,the bigger the population density is,and the greater the risk cost value is.
