摘　　要：为提高林区曲线道路驾驶员行车安全性和舒适性,采用驾驶模拟试验办法,利用眼动和心率作为评价指标,从动态视角对林区曲线道路行车舒适性进行评价研究。基于空间视距理论建立5种不同空间视距的林区曲线道路场景,研究结果表明,驾驶员瞳孔直径变化率和心率增长率随着空间视距增大而不断减小,驾驶舒适性不断增大。考虑瞳孔直径变化率和心率增长率的最小空间视距值为101 m和89 m,得出瞳孔直径变化率和心率增长率的空间视距适宜值为128 m和132 m。In order to improve driving safety and comfort of drivers on curved roads in forest areas,a driving simulation test was adopted to evaluate the driving comfort on curved roads in forest areas from a dynamic perspective using eye movement and heart rate as evaluation indexes.Based on the theory of spatial sight distance,five different spatial visual distance scenarios of curved roads in forest areas were established,and the results showed that the rate of change of pupil diameter and the growth rate of heart rate of the driver decreased with the increase of spatial sight distance,and the driving comfort increased continuously.The minimum spatial sight distance values considering the pupil diameter change rate and heart rate growth rate were 101 m and 89 m,and the appropriate spatial sight distance values considering the pupil diameter change rate and heart rate growth rate were 128 m and 132 m.
