基于心率变化指标的高原公路平曲线试验研究
Experimental Research on Horizontal Curves of Plateau Highway Based on Heart Rate Change Index
摘要
Abstract
In orde r to improve traffic safety on plateau highway, by using dynamic GPS, multi-channels cardiac electrophysiological polygraph and other testing equipments, road alignment, driving speed and drivers' psycho-logical and physiological reactions are tested on Qinghai-Tibet Highway of No.109 National Highway with the altitude ranging from 3567~4709 m. Taking increased rate of heart rate as the evaluation index and altitude, horizontal radius and driving speed as influencing factors, this study established and tested models of heart rate change applied to the altitude of 3567~3957 m and 4100~4709 m with the method of multiple regression analysis. Finally, according to Design Specification for Highway Route (JTG D20~2006), the minimal reference value of horizontal radius at different altitude intervals was explored. The results indicate that the accuracy of models is favorable, and the models can reflect changes of heart rate growth. The value of horizontal radius with the altitude ranging from 3567~3957 m should not be less than 300 m, and with the altitude ranging from 4100 to 4709 m it should not be less than 350 m.关键词
