摘要: 为明确驾驶人通过城市地下道路接入口时的眼动特性,选取重庆市渝中区解放碑地下环道,利用Tobii-Glasses-2可穿戴式眼动仪,采集40名驾驶人通过8类接入口时的眼动特征,统计驾驶人瞳孔面积、眨眼频率和扫视幅度等指标,并按接入口功能与方位分类,进行DEA(DataEnvelopmentAnalysis)评价,明确影响地下道路接入口布局对驾驶行为影响的重要指标。研究结果表明:弯道接入口驾驶人瞳孔直径均值达4.401 mm,显著高于直线段(4.183mm)和相邻接入口(4.123mm);联络道接入口视觉效率最佳,其综合效率为DEA强有效,水平扫视速度均值为261.698pixel∙s-1,高于其他类型接入口;直线段左侧接入口瞳孔直径均值(4.213mm)高于右侧(4.078mm),且综合效率小于1;组合型接入口综合效率为DEA强有效,其眨眼频率为0.607次∙s-1,高于接入口S(0.587次∙s-1)和接入口C(0.591次∙s-1),且瞳孔直径为4.123mm低于接入口C(4.401 mm)和接入口S(4.183mm)。研究结果揭示了地下道路接入口布局对驾驶行为的影响机制,可为优化城市地下道路接入口布局及提升行车安全提供更全面的理论支持。

Abstract: To clarify the eye movement characteristics of drivers when passing through the accesses of urban underground roads, the Jiefangbei Underground Ring Road in Yuzhong District, Chongqing was selected as the research site. Tobii Glasses 2 wearable eye tracker was used to collect the eye movement data from 40 drivers when passing through 8 types of accesses. The indicators, such as the pupil area drivers', blink frequency, and saccade amplitude, were statistically analyzed, and further classified according to the function and orientation of accesses and DEA (Data Envelopment Analysis) evaluation. It identifies the key indicators which influence the layout of underground road access on driving behavior. The research results show that: the average pupil diameter of drivers at curved accesses reaches 4.401 mm, which is significantly higher than that at straight segments (4.183 mm) and adjacent accesses (4.123 mm); the visual efficiency of the connecting road accesses is the best while their comprehensive efficiency is strongly effective by DEA, and the average horizontal saccade speed is 261.698 pixel · s-¹, higher than that of other types of accesses; The average pupil diameter at left accesses of straight segments (4.213 mm) is larger than that at right accesses (4.078 mm), and the comprehensive efficiency is less than 1; the comprehensive efficiency of combined accesses is strongly effective by DEA, with a blink frequency of 0.607 blinks·s-¹, which is higher than that of Access S (0.587 blinks·s-¹) and Access C (0.591 blinks · s-¹), while the pupil diameter is 4.123 mm, which is smaller than that of Access C (4.401 mm) and Access S (4.183 mm). These results reveal the mechanism by which the layout of underground road accesses affects driving behavior, and can provide more comprehensive theoretical support for optimizing the layout of urban underground road accesses and improving driving safety.
