摘　　要：基于行车安全性考虑，注重以人为本理念，应用医学、心理学等方面理论方法以及动态心电仪和GPS等仪器进行多类型实车道路实验．通过实验数据统计分析，建立驾驶员心率增量、车速、线形指标间的多元回归模型，应用模型讨论山区公路纵坡路段线形对驾驶员心理、生理影响．结果表明：直线下坡路段坡度3％～4％驾驶员心率增长均超过30％，心理最为紧张，较大坡度反而对驾驶员心理影响不大；直线上坡路段坡度与心理、生理反应相关性较差；弯坡组合路段线形综合指标与车速、心率增量近似线性相关．Considering the driving safety together with the humanism, the paper did many kinds of driving experiments by applying the theory of the medical science, psychology and kinetic ECG, GPS etc instruments. Based on data analysis, the regression model was established among the heart rate increment, speed and alignment index. The effect of the slope alignment on driverst psychology was also discussed. The result indicted that the drivers were the most intense and the heart-rates were over 30% when the grade is between 3%-4% on downgrade section＇s ; the minor relativity existed between the alignment and psychological reaction on upgrade sections; the alignment index is linear to the speed and the heart-rate increment on curve combined grade sections.
