摘　　要：我国大城市交通拥堵日益加剧,为解决交通拥堵需要隔离交通的交叉点,为此,城市下穿隧道的建设增多。本文以研究不同速度、不同光照补给、不同标志牌个数对驾驶人的视觉影响为目标,以控制变量的方法进行模拟实验,将驾驶人的模拟实验数据分类统计,运用统计分析原理分析不同因素对驾驶人的影响。首先,对某地下穿隧道入口段的交通特性进行调研与问题分析,利用UC-win/Road仿真软件进行实验场景搭建,设计5条下穿隧道入口段道路,设定不同参数(车速、标志牌数量、光照强度)。其次,通过iView X HED4眼动仪和模拟驾驶设备进行实验,利用其自带的分析软件BeGaze软件收集分析模拟驾驶过程中驾驶人的动态眼睛数据,包含驾驶人的注视、扫视数据以及热点图等。最后,利用CRITIC权重法得到不同限速、不同光照条件、不同标志牌数目下驾驶人的视觉负荷情况。最终得出限速宜在60~80km/h之间,同一个位置交通标志不宜超过5个,光照宜在300~500lx的结论。本研究结果可为城市下穿隧道入口段的交通标志牌数目、限速设定、交通标志牌补光等提供一定视觉动态理论支撑,同时为交通安全提供保障。Traffic congestion in big cities in my country is increasing.In order to solve traffic congestion,the construction of urban underpass tunnels has increased.This paper aims to study the visual impact of different speeds,different lighting supplies,and different number of signs on the driver.It conducts simulation experiments with the method of controlling variables,classifies and counts the driver's simulation experiment data,and uses statistical analysis principles to analyze different factors.Impact on drivers.First,the traffic characteristics of an underground tunnel entrance section were investigated and analyzed,and experimental scenarios were built using UC-win/Road simulation software,and 5 roads in the entrance section of the under tunnel were designed,and different parameters(vehicle speed,signboards were set.quantity,light intensity).Secondly,the experiment was conducted through the iView X HED4 eye tracker and simulated driving equipment.The BeGaze software,its own analysis software,collected and analyzed the dynamic eye data of the driver during the driving process,including the driver's gaze and saccade data and hotspot maps.Finally,the CRITIC weighting method is used to obtain the visual load status of drivers under different speed limits,different lighting conditions,and different number of signs.Finally,it was concluded that the speed limit should be between 60~80km/h,and there should be no more than 5 traffic signs at the same location,and the lighting should be between 300~500lx.The results of this study can provide certain visual dynamic theoretical support for the number of traffic signs,speed limit settings,traffic sign fill light in the entrance section of the city's undert tunnel,and provide guarantees for traffic safety.
