【摘要】：采用心理物理试验分析公路隧道内部视觉环境对驾驶员行车安全的影响,将E-prime 2.0软件与仿真驾驶模拟器相结合,对驾驶员在隧道内长时间行车中的速度判断准确率及反应时间两个指标进行分析,提出了利用标志标线构建公路隧道内韵律型标线系统的改善措施,以改善隧道内视觉环境,并利用数理统计方法及Logistics拟合分析对设计方案进行评价。结果表明:1)公路隧道内韵律型标线系统能提升隧道内驾驶员的速度判断准确率3.33%~11.66%;2)普通公路隧道场景中,被试者反应时间与隧道内行车时间存在显著关系,公路隧道内韵律型标线系统的场景中,反应时间与隧道内的行车时间没有显著关系,能有效缓解视觉疲劳现象;3)被试者反应时间的增加同时受隧道内视觉环境与行车时间的影响。公路隧道内韵律型标线系统能有效提高驾驶员的反应时间,适用于行驶速度为80 km/h、大于1 333 m的隧道。
[Abstract]:The influence of visual environment inside highway tunnel on driver's driving safety is analyzed by psychophysical test, and E-prime 2.0 software is combined with simulation driving simulator. This paper analyzes the accuracy of speed judgement and reaction time of driver in long time driving in tunnel, and puts forward the improvement measures of constructing prosodic marking system in highway tunnel by using marking line to improve the visual environment of tunnel. The design scheme is evaluated by mathematical statistics method and Logistics fitting analysis. The results showed that: 1) the prosodic marking system in highway tunnel could improve the speed judgment accuracy of drivers in the tunnel 3.33 and 11.6666 / 2) in the common highway tunnel scene, there was a significant relationship between the reaction time of the subjects and the driving time in the tunnel. In the scene of prosodic marking system in highway tunnel, there is no significant relationship between the reaction time and the driving time in the tunnel. The increased reaction time of the subjects was affected by the visual environment and driving time in the tunnel. The prosodic marking system in the highway tunnel can effectively improve the driver's reaction time and is suitable for the tunnel with a driving speed of 80 km/h, or more than 1 333m.
