Embodiment 1

[0061] 1. Data source

[0062] With the continuous development of the Internet and big data, the methods of monitoring vehicle driving behavior have become more diverse, including the car's own mileage and speed detection system, the most popular current GPS positioning system, and the emerging ADAS Internet of Vehicles alarm system, etc. . The data of this patent comes from the data summarized by ADAS equipment on a daily basis. The data collection process is as follows: figure 2 shown.

[0063] The daily driving behavior data of each driver is obtained through the platform database, with a total of 21,451 original data.

Abstract

The invention discloses a vehicle risk comprehensive evaluation method based on transition probability, which comprises the following steps of: 1) data acquisition and processing, 2) index classification determination: according to the influence of indexes on risks, dividing the indexes into A-class indexes with large influence on risks and B-class indexes with small influence on risks, the A-class indexes comprising an anti-collision early warning index and a fatigue driving alarm index, and 3) constructing a vehicle driving risk assessment model for the preprocessed Internet of Vehicles alarm data. Through the above steps, the invention provides the vehicle risk comprehensive evaluation method based on the transition probability, which is good in evaluation accuracy, good in use effect and high in applicability.

Description

technical field [0001] The invention relates to a vehicle risk comprehensive evaluation method, in particular to a vehicle risk comprehensive evaluation method based on transition probability. Background technique [0002] China's total automobile production and sales in 2018 was 12 million, an increase of 4% month-on-month, surpassing the total automobile production and sales of the United States by more than 40%, and it is currently the country with the fastest growing automobile industry in the world. In recent years, with the continuous improvement of social development and people's living standards, road vehicles have become very common in various fields. However, the road traffic safety problems it faces are becoming increasingly prominent. At present, road traffic accidents have become one of the most serious problems threatening people's public safety. Statistics from the World Health Organization (WHO) in 2016 show that more than 200,000 people die in traffic acci...
