| As a kind of professional drivers,heavy-duty truck drivers always drive between construction sites and concrete stations,with monotonous driving routes and high degree of job burnout.In addition,they often sacrifice sleep to earn more money when they are assigned more tasks,resulting in irregular sleep patterns.However,job burnout and sleep condition may lead to dangerous driving behavior of heavy-duty truck drivers,which may harm urban public safety.Therefore,this paper studies the influence of job burnout and sleep patterns on the driving behavior of heavy-duty truck drivers,which is of great significance for guiding them to drive safely and ensuring the safety of the entire road network.In this paper,two experiments are carried out for heavy-duty truck drivers.Experiment one uses the questionnaire survey of 321 drivers’ the Big Five personalities data,job burnout data,and driving behavior questionnaire data.This paper discusses the influence of Big Five personalities and job burnout on driving behavior of heavy-duty truck drivers.Both the Big Five personality and job burnout can predict dangerous driving behavior to some extent,among which the neuroticism,agreeableness and conscientiousness in the Big Five personality and the cynicism in job burnout have higher prediction levels.In addition,a structural equation model was established to explore the mediating role of job burnout between the Big Five personalities and driving behavior,and the results showed that job burnout played a complete mediating role between neuroticism and driving behavior,and a partial mediating role between agreeableness and driving behavior.Drivers of heavy-duty trucks with higher score of neuroticism and lower score of agreeableness have a weaker ability to control negative emotions,and are prone to fatigue and other negative emotions at work,which will lead to dangerous driving behaviors during driving and affect driving safety.In experiment 2,a field driving test of heavy-duty trucks was organized.A total of 11 professional drivers of heavy-duty trucks were invited to participate in the test.Each driver drove without interference for 3 consecutive days.In the experiment,we collected driving kinematics parameters as a measure of drivers’ driving behavior,and collected drivers’ working sleep time to determine the sleep pattern.According to the sleep duration and the number of sleep segments of heavy-duty truck drivers,their sleep patterns were divided into three categories,namely "high","medium" and "low".ANOVA was used to assess the influence of drivers’ sleep patterns on their driving behavior.Results show that the driver’s sleep patterns has significant effect on driving speed,the longer the driver sleeps,the faster the driver travels,and the greater the speed fluctuation,indicating that the frequency of the driver using the brake and accelerator pedal will increase.However,the speed limit on the test routes in this study is all 80km/h,and the speed of the vehicle does not exceed the speed limit,and the range of acceleration change is not obvious,so the driver keeps a safe and stable driving state.This shows that under the premise of ensuring the traffic safety of heavy-duty trucks,when the drivers sleep better,their driving performance is better and the driving efficiency is higher.The results of this paper show that job burnout and sleep patterns can all affect their driving behavior to some extent.It provides theoretical support for the professional driver education and training of heavy-duty truck drivers and the formulation of hours-of-service. |
