摘要
为了提高高原区道路的安全性,以交通工程学、心理学等理论为基础,利用先进的GPS、心电仪,血氧计等检测设备,对青藏公路道路线形、运行速度、驾驶员心生理反应等进行实地检测。在理论分析的基础上,对实测数据进行挖掘,分析高原区不同海拔高度驾驶员血氧含量对行车的影响及纵坡路段车辆运行速度和驾驶员心率增长率的变化规律。结合《规范》的规定确定了高原区道路纵坡坡度限值和最大纵坡折减值,为高原区道路的设计改造提供技术支撑,为公路设计规范的修订提供了新的依据。
In order to improve the highway safety in plateau area, the advanced GPS, ECG device, oximeter and other testing equipments were used to detect and investigate the road alignment, vehicle speed and drivers＇ psychological and physiological reactions on Qinghai-Tibet highway based on the theories of traffic engineering, psychology, etc. On the basis of theoretical analysis and utilization of the measured data, the impact of drivers＇ blood oxygen contents on traffic at different elevations of plateau was analyzed, and the variation of vehicle speed and growth of drivers＇ heart rates on the longitudinal slope sections. According to the Design Specification for Freeway Alignment, the gradient limit and the maximum value of grade compensation of highway in plateau area were defined, which can provide technical support for the design and reconstruction of highway in plateau area, and provide a new reference for the amendment of highway design specification.
