Research On The Influence Of Inhibitory Control On Risky Driving Behavior

Statistics from the traffic management department of the Ministry of Public Security show that driver risk driving behavior is the main cause of traffic accidents,and the number of traffic accidents and deaths caused by them account for more than 90% of the total.In a road traffic system consisting of a driver,a vehicle,and a road environment,the driver is not only the information processor and decision maker of the road traffic system,but also the main regulator and controller.Studies at home and abroad have shown that the driver’s cognitive ability is closely related to his risky driving behavior,and inhibitory control is a representative one of cognitive ability.Therefore,the research on the relationship between inhibitory control and risky driving behaviors will provide a theoretical basis for improving road traffic safety starting from driver’s cognitive ability and risky driving behaviors.Based on the summary and combing of the theoretical research on inhibitory control and risk driving,this study uses the cued Go/No Go task as the experimental paradigm for measuring the inhibitory control ability,introduces the research method of signal detection theory,and explores the driver’s inhibitory control ability in perception.Sensory differences.From the perspective of drivers’ risk driving behavior influencing factors,the characteristics of driver inhibitory control and risk decision-making behaviors are combined to establish simulated driving scenarios,and simulated driving experiments are used to evaluate the driver’s driving behavior performance in risk decision-making scenarios to study driver suppression.The relationship between inhibitory control and risky driving behavior.The main research contents and conclusions of this article are as follows:1.Combined with the research methods of psychological signal detection theory,this paper analyzes the characteristics of driver inhibitory control in perceptual perception.By introducing the alternative decision matrix in signal detection theory,the driver’s response in the cued Go/No Go paradigm task is divided into four cases: hit,underreport,false report,and correct rejection,and calculate the reaction probability of the four reactions.And through the conversion of psychological PZO value into the formula to obtain two important indicators of driver’s discernment and reaction tendency: discriminative index d ’and judgment standard β.The analysis results show that there is a significant difference in the discrimination and sensitivity of high-inhibitory control and low-inhibitory control drivers for noise and signal stimuli.High-inhibitory control drivers have a stronger discrimination for noise stimuli and are more sensitive to signal stimuli with higher sensitivity.2.The risk driving behavior characteristics of the driver are analyzed by simulating driving tasks.In related research on risk driving behavior,scholars mostly use subjective questionnaires such as driving behavior questionnaire to measure risk driving behavior,and rarely use driving behavior performance assessment methods.Therefore,this study designed six types of risk decision scenarios related to the characteristics of risk decision behaviors.Based on the driving simulator system,corresponding scenarios were established and simulated driving experiments were performed.Experimental results show that there is a significant difference between highinhibitory control and low-inhibitory control drivers in risk behavior tendencies and their corresponding driving behavior patterns.In the face of risk decision-making,low-inhibitory control drivers show a higher risk behavior tendency,and they tend to take a higher driving speed during driving,and have a higher proportion of overspeed behavior.In addition,the analysis results of SDLP also show that the driver with low inhibitory control has a weaker lateral control ability than the driver with high inhibitory control.3.In order to further explore the relationship between driver inhibitory control and their risky driving behavior,a correlation analysis is performed between objective indicators that characterize inhibitory control and risky driving behavior.The analysis results show that there are certain correlations between the four main objective indicators that characterize driver inhibitory control and the six main objective indicators related to risky driving behavior.Among them,the discriminative index d ’has a significant positive correlation with the speeding ratio;the judgment criterion β has a significant positive correlation with the driving time,and a significant negative correlation with the speeding ratio.Based on the analysis of the differences in risk driving behavior between high-inhibitory control and low-inhibitory control drivers,it can be concluded that there is a close relationship between driver’s inhibitory control and risk driving behavior.Inhibitory control may affects the driver’s risk behavior tendency and its correspondence to some extent driving behavior mode.
