Problems solved by technology

However, the driver's distracted driving behavior does not necessarily make the driver in a distracted state, and even in the distracted state, it may not directly cause the vehicle to be in a risky state; on the other hand, if only the distracted driving behavior The results will be limited to characterize the loss of driving performance caused by distracted driving behavior, and the actual driving risk caused by it will also not be considered
Therefore, only identifying the distracted driving behavior itself without considering the actual driving risk state and the loss of driving performance caused by it is divorced from the actua

Embodiment Construction

[0060] A method for risk assessment of distracted driving behavior provided by the present invention comprises the following steps:

[0061] (1) Determine the driving behavior type and driving task:

[0062] Select one type of normal driving behavior and five types of distracted driving behavior as the main evaluation content of risky driving behavior; then divide the selected distracted driving behavior into high and low task load;

[0063] The designed driving behavior and tasks are as follows:

[0064] The described normal driving behavior is focused driving: the subject has no other behaviors unrelated to driving during driving, no interference from other external environments, and carries out the driving test according to the well-trained test design plan and route;

[0065] The distracted driving behaviors described include:

[0066] Hand-held mobile phone calls: The subjects used their habitual hands to answer the phone calls of the test assistants throughout the driv...

Abstract

The invention provides a distraction driving behavior risk assessment method. The distraction driving behavior risk assessment method specifically comprises the following steps of determining a driving behavior type and a driving task, designing a driving scheme and collecting parameters, extracting an abnormal acceleration event frequency, carrying out risk level preliminary assessment on a driving behavior, carrying out double driving performance comparison and carrying out triple driving performance cross comparison. According to the method provided by the invention, the limitation that only distraction driving behaviors are studied is broken through, the distraction driving behaviors are improved to the height of risk analysis, driving performance evaluation is strictly performed on the selected distraction driving behaviors, and finally a strict risk level sorting result is obtained. Theoretical reference and practical guidance are provided for technologies such as a risk drivingbehavior identification technology, driver driving state safety evaluation and a man-machine co-driving situation control right switching scheme.

Description

technical field [0001] The invention relates to the traffic field, in particular to a risk assessment method for distracted driving behavior. Background technique [0002] During the driving process, the driver performs certain actions or ideas consciously or unconsciously, which makes the vehicle running state tend to or directly tends to be unstable, and poses a threat to the safety of the driver himself and other road users. Such behaviors are collectively referred to as risky driving behavior. Timely and accurate prediction of the driving risk caused by the driver's irregular behavior, together with reasonable intervention measures, can effectively avoid traffic accidents caused by the driver's factors. [0003] Distracted driving behavior is the most widespread and common type of driving behavior, with the highest number of accidents and fatalities. Previous research was mostly limited to the distracted driving behavior itself, and the research goal was to identify and...
