山区高速公路隧道进口路段环境因素对驾驶员生理的影响

摘要

In order to analyse the impact of environment factors of mountainous highway tunnel entrance section on drivers'' physiology,the field vehicle test on highway tunnel is conducted and the speed limit、luminance、road aligment and divers'' heart rate are collected.By using the method of characteristic point,the divergence of heart rate under the different condition of speed limit is analysed.On the basis of it,a forecast model is developde to analyse the impact of luminance,road aligment on Drivers'' Physiology in different limiting condition by using regression method.The result shows that(1)the bigger speed limiting difference,the greater heart rate variability at entrance;(2)under the same condition of speed limit,the greater luminance rate,the greater heart rate;(3)the combined influence of horizontal and vertical alignments of tunnel entrance on heart rate increment of drivers is obvious.On the basis of the validation of prediction models,safety methods at tunnel entrance are proposed.%为了分析山区高速公路隧道进口环境变化对驾驶员生理的影响,在山区高速公路隧道进行实车试验,收集了限速、亮度、道路线形与驾驶员心率等数据.采用特征点法分析限速差对心率的影响;在此基础上采用回归法,建立预测模型分析不同限速条件下亮度、道路线形对心率的影响.分析结果表明:限速差越大,进口路段心率变化率越大;限速条件相同时,亮度变化率越大,心率变化率越大;平纵线形指标对驾驶员心率增长率影响明显.在对模型进行验证分析的基础上,结合国内外相关研究成果,提出了隧道进口安全改善方法.
