摘要
为研究隧道前方与匝道路段处应急车道景观铺装及其对驾驶员视觉与行车安全的影响,通过现场调研的方法确定6种景观铺装方案,以Uc-win/Road软件搭建仿真场景,利用驾驶器、眼动仪分别进行模拟驾驶、驾驶员行车过程中视觉参数收集,得到驾驶员瞳孔面积变化率、注视点占比、反应时间3项评价指标。分析结果表明:1)不同应急车道景观铺装对驾驶员视觉有不同程度的影响;2)在隧道前方直行路段与匝道路段,6种铺筑方案均表现出较好的视觉效果,其中方案4有更低的瞳孔面积变化率、最低的反应时间,在视觉左前方、路面和应急车道有更高的注视点占比;3)选择方案4作为隧道前方直线路段与匝道曲线路段处应急车道的景观铺装方案,既可满足行车舒适性与安全性的要求,又可实现地域文化传播与景观宣传功能。
In order to study the landscape pavement of emergency lane in front of the tunnel and the ramp section and its impact on driver’s vision and driving safety,sixlandscape pavement schemes are determined by the method of on-site investigation.The simulation scene is built by UC win/road software,and the visual parameters are collected by the drivers and the eye trackers during the driving process to obtain three evaluation indexes:pupil area change rate,fixation rate and reaction time.The results show that:1)different emergency lane landscape pavement has different degree of impact on the driver’s vision;2)in the straight road section and ramp road section in front of the tunnel,thesesixpavement schemes all show goodvisual effects,among which scheme 4 has lower pupil area change rate,the lowest response time,and higher proportion of fixation points in the left front of vision,road surface and emergency lane;3)selecting scheme 4 as the landscape paving scheme of emergency lane at the straight section and ramp curve section in front of the tunnel can not only meet the requirements of driving comfort and safety,but also realize the function of regional culture communication and landscape publicity.
