Dynamic risk evaluation method for road dangerous cargo transportation on the basis of Internet of Things

Abstract

The invention discloses a dynamic risk evaluation method for road dangerous cargo transportation on the basis of the Internet of Things. The method comprises the following steps that: on the basis ofthe Internet of Things technology, collecting a dynamic parameter which influences a transportation risk; on the basis of the dynamic parameter, determining and correcting a transportation accident probability; determining an accident damage range, and calculating exposed populations on the basis of the dynamic parameter; on the basis of the dynamic parameter, dynamically evaluating driver safetyand the technical situation of the vehicle, and evaluating an enterprise management level according to an evaluation result so as to carry out associated offset on the transportation risk; on the basis of a vehicle speed parameter, establishing a traffic volume estimation model and a real-time estimation model for the population exposure of a high populated area; and finally, establishing a dynamic transportation risk evaluation model. By use of the method, the quantitative impact of the dynamic parameter which can be obtained in a transportation process on the transportation risk can be fullyconsidered, meanwhile, the method disclosed by the invention evaluates the transportation risk value in real time on the basis of the Internet of Things technology, can be used for transportation route selection and risk early warning, and improves the management level of dangerous cargo transportation.

Description

technical field [0001] The invention belongs to the technical field of road safety, in particular to a dynamic risk assessment method for road transport of dangerous goods based on the Internet of Things. [0002] technical background [0003] In recent years, the annual road transport volume of dangerous goods in my country has increased year by year. At present, more than 90% of dangerous goods need to be transported by road. In addition, dangerous goods are characterized by a wide variety, complex nature, and high degree of danger, which determines that road transport of dangerous goods is a fluid and high-risk operation, making its safety management quite difficult. [0004] The road transport volume of dangerous goods and the social demand in my country are growing rapidly, but the industry and enterprise management are still at a low level. On August 26, 2010, a double-decker passenger car and a tank truck (containing methanol) collided at the south of Huaziping servic...

AI Technical Summary

Problems solved by technology

[0005] At present, the application of big data based on the Internet of Things is not deep enough, and the regulatory parameters are relatively limited. Risk monitoring methods based on manual methods cannot meet safety requirements, and there is a lack of effective and comprehensive transportation risk assessment methods and means.
