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。
The psychophysical test is used to analyze the impact of the internal visual environment on the driving safety of drivers. The E-prime 2.0 software is combined with the simulated driving simulator to evaluate the driver’s accuracy in the long-time driving in the tunnel and the response time Two indicators were analyzed and the improvement measures of using prosody marking line to construct the prosodic marking system in highway tunnel were put forward to improve the visual environment in the tunnel. The mathematical model and Logistics fitting analysis were used to evaluate the design scheme. The results show that: 1) the rhythm type marking system in highway tunnel can improve the speed of the driver in the tunnel to judge the accuracy of 3.33% ~ 11.66%; 2) In the ordinary highway tunnel scene, the response time of the respondent and the driving time in the tunnel are significant In the scene of rhythm type marking system in highway tunnel, the reaction time has no significant relation with the travel time in the tunnel, which can effectively alleviate the visual fatigue phenomenon.3) The response time of the subjects is increased at the same time by the visual environment within the tunnel and driving The impact of time. The rhythm type marking system in highway tunnel can effectively improve the reaction time of the driver, which is suitable for the tunnel with driving speed of 80 km / h and more than 1333 m.
