摘　　要：为探究山区双车道公路隧道口路段驾驶心理负荷的变化特性,本文采用实车试验的研究手段,招募27名驾驶人作为被试,选择重庆市境内的9座隧道作为试验场景,采集驾驶人、车辆和驾驶环境的行车数据,使用驾驶人的心率增长率表征驾驶心理负荷。通过数据分析,对驾驶人在隧道口路段的驾驶心理负荷与亮度和速度的相关性进行研究。结果表明,山区双车道公路隧道入口段的驾驶心理负荷大于出口段;在环境亮度小于500 cd·m^(-2)时,驾驶心理负荷对亮度的变化更为敏感,进而提出亮度变化率的计算公式,当亮度变化率在60%时,黑洞和白洞效应对驾驶人的心理影响趋于相同;在隧道口路段,速度对驾驶心理负荷具有放大效应;根据驾驶心理负荷值,划分隧道口路段的驾驶舒适度区间,提出基于驾驶舒适度需求的亮度变化率和速度的安全阈值,并给出计及亮度变化率和隧道口净空高度的亮度曲线。To investigate the changing characteristics of driving psychological load in the tunnel portal sections of a two-lane highway in a mountainous area,this paper conducted a real vehicle test with 27 drivers as the subjects in nine tunnels in Chongqing.The driving data of drivers,vehicles and driving environments were collected,and the heart rate growth of the drivers was used to characterize the psychological load of driving.The correlation between drivers'driving psychological load and luminance and speed in the tunnel portal section was investigated through data analysis.The results showed that the psychological load of driving in the entrance section of a two-lane highway tunnel in a mountainous area was greater than that in the exit section.When the ambient luminance is less than 500 cd·m^(2),the driving psychological load is more sensitive to the luminance change rate,and then the formula for the luminance change rate is proposed.When the luminance change rate is 60%,the psychological impacts of the black hole and white hole effects on drivers tend to be the same.In the tunnel portal section,speed has an amplifying effect on driving psychological load.Based on the driving psychological load value,this study also defined the driving comfort interval of the tunnel portal section,proposed the safety thresholds of luminance change rate and speed based on the driving comfort demand,and developed the luminance curves in consideration of the luminance change rate and the clearance height of the tunnel portal.
