摘　　要：为探究直线公路隧道入口段驾驶者的视觉负荷,首先,通过实车试验采集5种视觉指标,采用Topsis改进因子分析法建立视觉负荷评价模型;然后,分析不同时间及位置下视觉负荷的变化特征,基于构建的视觉负荷曲线提出行车舒适评价标准,并运用已发表数据验证构建负荷模型的泛化能力;最后,通过敏感度分析探究视觉指标对视觉负荷的影响程度。结果表明:当驾驶者位于距洞口-13~55 m(12:00)、-10~49 m(15:00)时,视觉负荷超过临界值(0.906),驾驶者的行车舒适度和安全性极低;洞口驾驶者的视觉负荷值和接近度远大于洞内和洞外;18:00的视觉负荷和接近度远低于12:00和15:00。视觉指标的敏感度参数从大到小依次为注视时间、瞳孔面积、注视次数、扫视幅度、扫视速度。In order to investigate the visual load of drivers at the threshold zone of linear highway tunnels,five visual indicators of drivers were collected through the real vehicle test.A visual load evaluation model was developed by the Topsis improved factor analysis method,the visual load at different times and locations was analyzed,the evaluation criteria of driving comfort were proposed based on the constructed visual load curve,the generalization ability of the constructed load model was verified by using published data,and finally,the influence of visual indicators on visual load was investigated by sensitivity analysis.The results show that when the driver locates about -13 m to 55 m(12:00)and -10 m to 49 m(15:00)from the entrance,the visual load exceeds the boundary value(0.906),indicating the driver's driving comfort and safety is extremely low.The visual load and closeness of the drivers near the entrance are much greater than those inside and outside the entrance,and the visual load and closeness at 18:00 are much lower than those at 12:00 and 15:00.The sensitivity parameters of the visual indicators are fixation duration,pupil area,fixation time,saccade range,saccade speed in descending order.
