Traffic engineering potential safety hazard evaluation device and method

Abstract

A traffic engineering potential safety hazard assessment device comprises: a risk accident case library module, which is used for establishing an accident tree based on road construction risks by analyzing accident historical data; a construction division module which is used for dividing the road construction process into a plurality of construction sections and dividing each construction sectioninto a plurality of construction procedures, wherein the construction sections in the road construction process are sorted and numbered according to the construction sequence and are 1, 2,..., k,...,n, and n represents the total number of the construction sections of the engineering project; a potential safety hazard evaluation module which is used for evaluating the road construction risk basedon a fuzzy polymorphic Bayesian network; an input and display module which is used for inputting cases and displaying evaluation results; and a management server module which is used for data transmission, calculation, storage and display. The device improves the comprehensive evaluation of each construction risk factor, and enables the risk evaluation level of each construction risk factor to behigh in accuracy.

Description

technical field [0001] The invention belongs to the technical field of engineering projects, and relates to a device and method for evaluating potential safety hazards in traffic engineering. Background technique [0002] With the continuous development of my country's economy, the construction industry has also developed rapidly in recent years, and the projects undertaken by the construction industry in the fields of civil, industrial, and urban infrastructure are increasing. At the same time, with economic development and scientific and technological progress, construction projects are gradually developing in the direction of large-scale, complex, and diverse. However, during the construction of engineering projects, the construction site operating environment is complex, with high mobility of people and machines, and harsh production conditions. , The construction period is long, the risk factors such as many hazards and the relatively low comprehensive quality of the st...

Problems solved by technology

[0005] At present, the identification and risk evaluation of risk factors in the risk management research of road construction projects are more focused on the overall and static risk level division using expert experience, which can serve as a reference for projects with experience. However, for projects with less experience, this method may cause misjudgment, so it is necessary to propose a more objective and practical method
