Study On The Change Of Heart Rate Of Highland Highway Driver

With the rapid development of highway transportation network in China,the highway coverage rate and highway mileage of the western plateau area are also increasing.Through the research and research of the relevant highway,people's understanding and understanding of the highway is deepening.High-altitude areas to road transport as the main means of transport,these areas have a very different with the plains of the transport environment,Mainly for the low oxygen,low pressure,cold climate,dry,single road landscape,complex terrain,poor environment and so on.Drivers driving in high altitude areas,their physical and psychological aspects will be affected by environmental conditions,these effects mainly in the driver's visual,reaction characteristics and physiological characteristics and so on.Therefore,Based on the data obtained from the biofeedback experiment,it is very important to study the change of heart rate of the driver of the plateau highway and to further explore the driving suitability of the driver in the special environment of the plateau area.In this paper,a large number of field driving tests were conducted on the pilot of the transportation activities in 314 national highway in Pamir Plateau,Xinjiang.Using the physiological index data measured by the driving test,the physiological and psychological changes of the driver and the dominant factors influencing the driver's heart rate change were obtained,and the influencing factors of the heart rate change were analyzed and confirmed.On the basis of this,the heart rate variability was used as the indicator of the change of the heart rate of the plateau highway driver.Taking the altitude,continuous driving time and driver age as the influencing factors,the method of qualitative analysis and quantitative analysis was used to focus on the high altitude environmentThe change of the heart rate of the driver is analyzed and discussed.The results show that the correlation between continuous driving time and altitude and HF and LF /HF is higher.The higher the altitude of the plateau highway,the longer the driver's age,the longer the driving time,the more obvious the change of heart rate.
