Problems solved by technology

[0004] Existing fatigue driving identification methods rely on on-board equipment, leading to data security risks, and damage to on-board equipment will lead to problems that cannot be obtained, or judge whether the driver is fatigued according to the fixed driving speed of the road section. The judgment of fatigue driving cannot adapt to different road conditions, and it is easy to misjudge or miss the judgment

Embodiment Construction

[0023] The technical solution of the present invention will be described in detail below.

[0024] The invention provides a method for judging fatigue driving based on the real-time traffic conditions of road sections, comprising the following steps:

[0025] Step S0, recording the transit time of various types of vehicles passing through the road section in each time period of each road section;

[0026] Step S1, select a car type concerned, there are large cars or small cars;

[0027] Step S2, for each section of each time period, first try to fit the vehicle transit time with two Gaussian mixed models of normal distribution, the first normal distribution represents the transit time distribution of vehicles without stopping and resting in this section, the second The two normal distributions represent the transit time distribution of vehicles that stop and rest on the road section;

[0028] Step S3, for a section of road in a certain period of time in step S2, if the sampl...

Abstract

The invention relates to a method for judging fatigue driving based on real-time traffic conditions of road sections. This method uses the time spent by the actual vehicle group for dynamic modeling, and describes a fatigue (continuous) driving discrimination model that reflects timeliness and road characteristics. Since the present invention judges whether the vehicle is driving with fatigue based on the real-time traffic condition of the road section, it can accurately judge the fatigue driving situation of the vehicle (driver).

Description

technical field [0001] The invention relates to a method for judging fatigue driving based on real-time traffic conditions of road sections. Background technique [0002] With the rapid development of the current economy and society, the development and growth of the logistics industry, and the increasingly fierce competition in the passenger and freight market, some car owners and drivers drive continuously for a long time in order to seek economic benefits, resulting in fatigue driving and frequent serious road traffic accidents. [0003] Fatigue driving refers to the imbalance of physiological and psychological functions of the driver after driving continuously for a long time, and the phenomenon of objectively declining driving skills, which causes the driver to act late or prematurely, stop operation or correct the time. Improper and other unsafe factors can easily lead to road traffic safety accidents. [0004] Existing fatigue driving identification methods rely on o...
