Problems solved by technology

However, the use of BPNN to evaluate rail transit operation safety requires a large number of training samples. In practice, when BPNN is used, the training samples are often limited and uneven, so the parameters are not easy to determine, which affects the evalu

Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] like figure 1 Shown is the flow chart of the rail transit operation safety evaluation based on GA-BP neural network according to the present invention.

[0032] The safety evaluation model based on GA-BP neural network established by taking 25 data of 30 data of a rail transit line in Ningbo as the learning sample input is used for learning and training. By inputting the influencing factors (scientific indicators) to be evaluated (verification samples), the evaluation of the overall state of rail transit operation safety is obtained.

[0033] Specific implementation steps:

[0034]Step 1: Determine the index system (influencing factors) of the safety status of rail transit operation, review the actual safety situation of rail transit operation and relevant laws and regulations and literature, proceed from the actual safety production...

Abstract

The invention discloses a rail transit operation safety evaluation method based on a GA-BP neural network. The method comprises the following steps: step 1, determining an index system of a rail transit operation safety state; step 2, constructing a GA-BP neural network model, wherein the neural network is of a three-layer neural network structure comprising an input layer, a middle layer and an output layer; step 3, collecting a data sample; step 4, training the GA-BP neural network, and inputting the training sample to train the GA-BP neural network; step 5, through the above steps, acquiring parameters such as corresponding weights of the GA-BP neural network and a trained neural network security evaluation model; and step 6, evaluating the safety state of the rail transit. According to the method, the workload of manual evaluation is reduced, the subjective influence of evaluation personnel is greatly reduced, the accuracy and objectivity of a rail transit operation safety evaluation result are improved, and technical support is provided for mastering rail transit operation safety operation.

Description

technical field [0001] The invention relates to a rail transit operation safety evaluation method based on a GA-BP neural network, belonging to the technical field of safety engineering. Background technique [0002] Urban traffic problem is one of the main problems encountered in the development of modern cities. An effective way to improve the overall traffic in the city is to develop urban rail transit. Urban rail transit has the characteristics of high speed, punctuality, and large passenger capacity. With the rapid development of China's economy, China's urban rail transit industry is entering a period of rapid development. The construction and operation of urban rail transit has effectively relieved the pressure on urban traffic, and also favorably promoted the development of urban areas. As a place with intensive personnel activities, the safety of rail transit has always been the focus of people's attention. Once a subway operation accident occurs, personnel and ...
