基于线性诱导的高速公路隧道边墙效应调控方法研究

Study on Regulation Method of Side Wall Effect of Expressway Tunnel Based on Linear Induction

文中提出线性诱导理念,基于E-prime平台开展室内仿真模拟试验,并以30名被试者的反应时间和眼动数据作为评价指标衡量调控方法的有效性.结果表明:线性诱导方案能有效改善高速公路隧道边墙效应,降低驾驶人的反应时间,缓解驾驶人的紧张程度;采用点状设施方案或线性诱导方案的点状设施+短线条设施时,亮灯率对驾驶人反应时间有显著影响;采用点状设施+短线条设施+长线条设施或点状设施+短线条设施+长线条设施+环状设施的方案时,亮灯率对驾驶人反应时间没有显著影响,且方案为后者时,驾驶人反应时间的变异系数小,瞳孔面积变化率更稳定.

The concept of linear guidance was put forward,and indoor simulation experiments were carried out based on E-prime platform.The response time and eye movement data of 30 subjects were used as evaluation indexes to measure the effectiveness of the regulation method.The results show that the linear guidance scheme can effectively improve the side wall effect of expressway tunnel,reduce the driver’s reaction time and relieve the driver’s tension.The lighting rate has a significant effect on the driver’s reaction time when the point facility scheme or the linear guidance scheme is used.When the scheme of point facilities+short line facilities+long line facilities or point facilities+short line facilities+ring facilities is adopted,the lighting rate has no significant effect on the driver’s reaction time.And when the scheme is the latter,the coefficient of variation of driver’s reaction time is small and the rate of change of pupil area is more stable.
