摘要
以驾驶员心率变化与长大下坡路段道路线形指标的关系为研究对象,从对驾驶员的心理影响角度研究长下坡路段道路线形的交通安全影响,应用数理统计和数学建模等方面的理论方法为基础,建立驾驶员心率路段线形指标间的回归模型,并分析长大下坡线形指标对驾驶员心理的影响,可为长大下坡路段的道路线形设计和现有危险长大下坡路段的改造提供参考。
The research on the influence of the long slope alignment on drivers′ psychology is of great benefit to the design of long slope sections and traffic safety.Using mathematical statistics and mathematical modeling,a regression model of the driver′s heart rate and long slope alignment index is established as the speed and long slope alignment index are taken as independent variables.At last the paper utilizes the model to discuss the effect of the long slope alignment index on traffic safety and drivers′ psychology,and then provides technical support for long slope sections and alignment design and transformation.
