中国山区双车道公路具有里程长、交通量大、超荷载运行等特点,大部分已进入养护期.受地形地貌限制,养护作业区路段事故频发,严重影响了运输效率.在大量实地数据采集的基础上,通过心生理理论与数理统计法分析,山区双车道公路作业区路段不同交通流状态下驾驶员的心生理变化规律,确定了山区双车道公路作业区路段驾驶员注视时间阈值,最终分析出驾驶员不同注视点的注视时间值与心生理特性.结果表明,山区公路作业区驾驶员的注视时间阈值为381 ms;路面障碍物、过渡段路面、前车车尾为驾驶员在作业路段关注最多的点.%China's mountain two-lane highway has long mileage, large volume of traffic, and overloaded opera-tion.Most of them have entered the maintenance period.Because of the limit of geography, accidents happen fre-quently in maintenance operations area, and this affect the transport efficiency seriously.The use of advanced dy-namic heart physiological detection equipment in a large number of field data collection on the basis of.The physio-logical and physiological changes of the driver under different traffic flow in the area of the two-lane highway operat-ing area in the mountainous area were analyzed by the theory of cardiac physiology and mathematical statistics, and it is gained by analysis that the driver in the free flow, followed by the state of attention and time to focus on the cu-mulative percentage of the relationship between the model.And thus determine the mountain two-lane highway op-erating area section of the driver to watch the time threshold.Finally,it is analyzed that the gaze time value and car-diac physiological characteristics of the different fixation points of the driver.The results show that the threshold of watching time of driver in mountainous road work area is 381 ms.The pavement obstacle, the transitional section pavement and the rear of the front car are the points that drivers pay most attention to in the working section.
