Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings.

[0042] see figure 1 , the present invention first designs the acceleration index by analyzing the speed data of each driver, and uses the characteristic index to identify the driver's driving behavior sequence. Then, using the obtained alarm type of each driver, the K-Means mean clustering method is used to divide the drivers into low-risk drivers, medium-risk drivers and high-risk drivers. The classification of driver risk level is the basis of driver risk level identification, and whether the classification is reasonable or not directly determines the success or failure of the identification algorithm. After the comprehensive model is trained with partial data, the driving behavior sequence is recognized.

[0043] Among them, driving behaviors include fast deceleration, slow deceleration, normal driving, slow acceleration, and fast acceleration.

Abstract

The invention discloses a method for detecting a driver risk level based on a comprehensive model. According to the method, speed data of a vehicle and different alarm types of a driver are collected,a driving behavior is judged, the risk level of the driver is classified, the risk level of the driver is identified by utilizing the trained comprehensive model, and then the risk level of the driver is judged by utilizing an identification result. The method mainly serves a transportation enterprise safety management system, when it is recognized that the driver is a high-risk-level driver, corresponding management training measures can be taken so as to improve the safety of the driver, the practical use of the method can reduce casualties and property losses caused by traffic accidents, and the overall safety of a traffic system is improved.

Description

technical field [0001] The invention belongs to the field of traffic safety, and in particular relates to a method for detecting a driver's risk level based on a comprehensive model. Background technique [0002] With the rapid development of the national economy and the acceleration of the urbanization process, the number of motor vehicles and road traffic in my country has increased rapidly, and the problem of traffic accidents has become increasingly prominent. Existing studies have shown that driver factors are the main cause of traffic accidents. Drivers with different driving risk levels have different contributions to traffic accidents. Drivers with low risk levels may cause fewer or even avoid traffic accidents, while drivers with low risk levels may cause fewer or even avoid traffic accidents, while Traffic accidents caused by drivers with higher risk levels may be more serious. Therefore, it is particularly important to conduct in-depth research on the identificat...
