摘要:
为定量描述驾驶员视觉搜索模式与公路平面线形的相关性,基于眼动试验展开对驾驶员视觉搜索模式的研究.首先通过室内试验获得驾驶员在不同公路平面线形条件下的眼动指标; 其次,从宏观层面到微观层面分析驾驶员视觉搜索模式与平面线形的相关性; 最后,通过室外试验分析验证室内试验的有效性和结论的可靠性.结果表明:在不同平面线形条件下,驾驶员注视持续时间具有显著差异性.此外,平曲线半径、缓和曲线A值与驾驶员注视持续时间有明显的相关性.应用拉格朗日中值定理发现,当平曲线半径R>1.5 km或直线段结束前100 m时驾驶员注视持续时间变化显著,即为驾驶员视觉搜索变化的关键点.
Abstract:
In order to quantitatively describe the correlation between drivers’ visual search behavior and highway horizontal alignment, the study of drives’ visual search behavior based on eye movement experimental was carried out. Firstly, the eye movement indexes under different highway horizontal alignment conditions were obtained by laboratory test; Secondly, the correlation between drivers’ visual search behavior and highway horizontal alignment were analyzed from macroscopic level to microcosmic level; Finally, the laboratory testing’ effectiveness and the results’ reliability were verified by outdoor testing. The results show that the index of fixation duration has significant difference under different horizontal alignment condition. Moreover, drivers’ fixation duration has remarkable correlation with horizontal radius R and the value of A. Using Lagrange mean value theorem, it is found that drivers’ visual search behavior will change obviously when radius is greater than 1.5 km or when distance between line section and curve section is less than 100 m. It would be a crucial point in drivers’ visual search behavior.
