Embodiment

[0106] The real-time assessment method of road transport safety risk based on data mining of the present invention will be described below, and 489 passenger and freight vehicle traffic accident investigation reports are processed by this method, and the validity of the method is verified by 70 reports.

[0107] Step 1: Obtain 489 passenger and freight vehicle traffic accident investigation reports and store them in the database.

[0108] Step 2: According to the national standards such as the public safety industry standards of the People's Republic of China, road traffic management information collection specifications, and road traffic accident information codes, 38 items of traffic accident information are extracted as the basic road transportation safety risk source list as shown in Table 1. The list of 38 basic risk sources extracted is shown in Table 1. The list of 11 basic accident states extracted is shown in Table 2.

[0109] Table 1 List of basic road transport saf...

Abstract

The invention discloses a road transportation safety risk real-time evaluation method based on data mining, and the method is calculated based on the following model: R = P.M, R is a safety risk evaluation value, P is a risk source or accident occurrence probability evaluation index, and M is a risk source or accident possible damage consequence severity evaluation index. According to the invention, based on mining of a large amount of text data, dynamic real-time acquisition of P and M is realized, real-time evaluation of risk values is obtained, real-time dynamic change of risk evaluation along with risk source coupling is realized, risk evaluation considering risk source causal relationships is realized, and automatic updating of evaluation thresholds is realized.

Description

technical field [0001] The invention relates to the technical field of road transportation safety, in particular to a method for real-time evaluation of road transportation safety risks based on text mining, data correlation mining, and machine learning technologies. Background technique [0002] Realizing road transportation safety risk assessment in advance is the basis for ensuring road transportation safety production, and it is also a key link in road transportation safety risk management and control. Risk assessment is generally based on risk identification. At present, there is a bottleneck problem in the risk identification link: the identification of road transport safety risks is largely based on traffic accident reports, but the analysis of risk sources and accident states in traffic accident reports basically relies on Manual, there are disadvantages such as heavy workload and relying on the cognition of experts. [0003] There are also two bottlenecks in the ri...
