摘要
为提高村镇道路行车安全性,实地检测村镇道路会车过程中车速和驾驶员的心生理反应参数,融合交通工程学、心理学和人因工程学的基础理论,探究会车过程中车辆的运行特性与驾驶员心率变化间的关系。首先整体分析试验中所有会车过程的行车状态,然后分析直线段上单次会车过程中车速变化与心率增长率的关系,最后分析曲线段上车速、心率增长率与平曲线半径的关系。结果表明:在村镇道路上,驾驶员会车时存在明显的紧张行为;在会车时域内车速、驾驶员心率增长率呈U型变化,且两者变化趋势相反;会车时的车速随道路平曲线半径的增加而增大,心率增长率随平曲线半径的增加而减小。
For the sake of improving the safety of driving on village road,the paper was aimed at analyzing the relations between the running characteristics of the vehicle and the physiological state of the driver during the vehicles meeting process based on the theories of traffic engineering,psychology and human factor engineering. Data on the driver’s psychological and physiological changes and the vehicle speed and other parameters were obtained through field testing. The speed change of the vehicle during the vehicles meeting and the driver’s heart rate growth rate were analyzed. The relationship between the vehicle speed change and the heart rate growth rate during the meeting process on the straight line segment was studied. The relationships between the vehicle speed,the growth rate of driver ’s heart rate and the flat curve radius on the curved section were analyzed. The results show that the driver feels an obvious tension when the vehicles crossing each other,and the vehicle speed in the meeting duration undergoes an U-shaped change process,however the change in the corresponding heart rate growth rate undergoes a process opposite to the U-shaped change process,and that when the curve radius gets larger,the vehicles speed get higher when crossing each other,however the growth rate of driver’s heart rate gets lower.
