Embodiment Construction

[0023] The present invention will be described in further detail in conjunction with the accompanying drawings.

[0024] Among the many factors of road traffic accidents, the human factor plays a major role, which is an important issue in the study of driving safety. The increase of traffic accidents due to the reduced level of vigilance of drivers has become a serious problem. Statistics show that nearly 87.5% of traffic accidents are caused by bad behaviors of drivers. To study the influence of human factors on traffic accidents, that is, to study the influence of drivers' driving behavior on traffic accidents.

[0025] The driver's driving behavior is a three-cycle process of information perception, information judgment, and feedback execution, and any error in any process may cause traffic accidents. Factors affecting driving behavior are divided into 1) internal factors: physiological and psychological factors of the driver. Physiological factors mainly include the driv...

Abstract

The invention discloses an analysis method for factors of road traffic accidents based on a Logistic model. The method specifically comprises the steps of 1, from four aspects of people, vehicles, roads and environment, analyzing the influences of a driving speed, a travel time and four rapid behaviors on the road traffic accidents; on the basis of the analysis of the factors influencing the road traffic accidents, establishing the Logistic regression model, and analyzing the influences of the road traffic factors on the severity of occurred traffic accidents; 3, according to past statistic data of the road traffic accidents, verifying the Logistic regression model. The four rapid behaviors comprise rapid acceleration, rapid deceleration, rapid braking and sharp turning. According to the analysis method for the factors of the road traffic accidents based on the Logistic model, by analyzing the factors influencing the traffic accidents from different aspects, the factors which have relatively serious influences on the occurred traffic accidents can be analyzed out; on the basis of data of the traffic accidents which occur in reality, the model can be verified, and the result can be analyzed.

Description

technical field [0001] The invention belongs to the field of data processing for specific applications, and in particular relates to a method for analyzing factors of road traffic accidents based on a Logistic model. Background technique [0002] With the development of the economy, the number of motor vehicles in our country has increased rapidly. The increase in vehicles has brought convenience to travel, but at the same time traffic safety can be seen everywhere. According to data, there were 196,000 traffic accidents in 2013, with more than 60,000 deaths and more than 60,000 injuries. The number of people is more than 220,000, and the economic loss caused is about more than 1 billion. For road traffic accidents, how to avoid serious road traffic accidents and how to reduce the number of casualties in accidents is an important content of road safety research. [0003] Most of the existing research on road accidents in our country focuses on how to reduce or avoid road tr...
