Problems solved by technology

[0003] Freight safety risk monitoring and evaluation technology is one of the hotspots in the field of road traffic safety risk research. At present, the theoretical research on the evaluation and evaluation of road traffic safety risks is mainly aimed at static risks, without considering the system dynamics of risks, which leads to its safety emergency response. And the early warning response is relatively lagging, and the application is subject to certain restrictions

Embodiment Construction

[0040] Below in conjunction with accompanying drawing and specific embodiment, this technical scheme is further described:

[0041] A freight safety evaluation model based on multiple risk sources of people-vehicle-road-cargo, including the following steps:

[0042] The first step: build a freight safety information perception system based on people-vehicle-road (environment)-cargo, and identify drivers, vehicles, roads (environment) and cargo information. The framework of the constructed information perception system is as follows: figure 1 shown.

[0043] First, two star-level video sensors are installed directly above the driver's position in the cab and above the right of the co-pilot to collect the driver's front view and side view images in real time, and build a driver detection model. Sparse representation theory is used to carry out Driver posture recognition, obtain driver information matrix B 1 ’; Secondly, in terms of vehicles, the satellite positioning terminal...

Abstract

The invention discloses a freight transportation safety evaluation model based on a man-vehicle-road-freight multi-risk source. The model is characterized in that a freight transportation safety sensing system is constructed and driver, vehicle, road (environment) and freight information is obtained; a causing factor of a freight vehicle accident is analyzed by using an accident causation theory, attribute sets of four kinds of man, vehicle, road, and freight risk sources are defined, and the attributed sets are analyzed and screened by using an accident tree analysis method; according to the screened attribute sets, a freight transportation safety risk index system is built by using an analytic hierarchy process and weights of the driver, vehicle, road(environment) and freight information factors for accident occurrence are determined; and according to the established integrated freight risk evaluation index system as well as all evaluation index weights, a freight transportation safety risk evaluation model is established by using a fuzzy evaluation theory. Therefore, the technical support for intelligent early warning can be provided for the road freight transportation safety work.

Description

technical field [0001] The patent of the present invention relates to the field of road cargo safety risk research, especially in the aspects of risk source identification and freight safety evaluation of road cargo transportation. Background technique [0002] In recent years, with the rapid development of the national economy and society, the status of road freight in the comprehensive transportation system has been increasing. But at the same time, it also brings huge challenges to the safe operation and supervision of freight transportation. Therefore, it is necessary to study the key technologies of safety risk assessment around the four safety risk sources of road freight drivers, freight vehicles, road conditions and on-board cargo by means of technical means such as intelligence, informatization and digitization, so as to realize the dynamics of road freight transportation. Risk Identification. This key technology research is in line with the macro requirements of ...
