Problems solved by technology

[0004] From the research status at home and abroad, scholars from various countries have carried out a series of research on the security risk identification, risk warning and control of the transportation network system, but most of the previous research results focused on a single transportation network or a single transportation mode. The research object is the comprehensive transportation network, which is quite different from the single transportation network in terms of the complexity of the transportation network composition and the diversity of transportation modes. There is a lack of targeted research on the comprehensive transportation network security risk assessment. Research

Embodiment

[0027] refer to Figure 1-3 , a security risk point identification method for an integrated transportation network. First, identify the infrastructure in the integrated transportation network, analyze the relationship between the infrastructure, and lay the foundation for the calculation of security risk propagation under event conditions; secondly, Combining with the results of security risk propagation, calculate the possibility of a single infrastructure emergency in the network and the possible results; finally, calculate the security risk value of the infrastructure in the network, and according to the risk tolerance curve of the manager, the network security Risk points are identified.

specific Embodiment approach

[0028] This patent firstly identifies the infrastructure in the integrated transportation network, analyzes the relationship between the infrastructure, and on this basis, identifies the security risk points of the integrated transportation network system, among which, the infrastructure security risk assessment in the network See flow chart figure 1 . The specific implementation of this patent is as follows:

[0029] (1) Analysis of the relationship between the comprehensive transportation network infrastructure

[0030] This patent focuses on the infrastructure network composed of highways, railways and other road section facilities and hub nodes such as passenger and cargo hubs and aviation stations. Between different facilities, the intensity of security risk transmission is affected by the relationship between facilities, and the relationship between facilities is divided into the following four categories:

[0031] 1) Physical correlation: If the state of one facility...

Abstract

The invention discloses a safety risk point identifying method for an integrated traffic transportation network, and the method comprises the following steps: 1), analyzing the correlation of the infrastructures of the integrated traffic transportation network; 2), determining an evaluation index for an event influence result; 3), determining an event influence diffusion matrix; 4), estimating therisk of the infrastructures of the integrated traffic transportation network; 5), determining a safety risk point of the integrated traffic transportation network. The invention aims at solving a problem of an existing integrated traffic transportation network for advanced prevention and control, and innovatively proposes the safety risk point identifying method for the integrated traffic transportation network. The method meets the demands of an integrated traffic transportation manager for the safety risk prevention and control, improves the natural disaster and emergency handling capability of the integrated traffic transportation network, improves the reliability of a traffic transportation system, and lays a foundation for the guaranteeing of the national transportation safety.

Description

technical field [0001] The invention belongs to the field of intelligent transportation, and in particular relates to a method for identifying security risk points of an integrated transportation network. Background technique [0002] To speed up the development of safe transportation, the concept of safe development must be permeated in all fields and the whole process, and the ability to prevent, manage and control the safe development of transportation should be greatly improved. According to the spirit of the "Opinions of the Ministry of Transport on Promoting Safety Production Risk Management" (Jiao'an Jianfa [2014] No. 120), on the basis of existing safety management, introduce risk management concepts, optimize safety management, and adhere to the principle of "prevention first" The principle of "main" and the gates are moved forward. Through "risk identification, risk assessment, and risk control", "after-event remediation" is changed to "pre-event control". The abi...
