摘要
选取浙江省多条公路隧道,开展实车试验,研究单向及双向通行隧道中间段驾驶人的视觉特性。通过驾驶人兴趣区域视点分布比率、驾驶视觉搜索区域面积及重心坐标等指标,对比分析单向通行和双向通行隧道中间段驾驶人视点分布差异,从而定量分析单向及双向通行条件对行车安全的影响。研究发现,双向通行隧道中间段驾驶人视野横向搜索范围较小,纵向视觉搜索稳定性较低;单向通行隧道驾驶人视点左右切换的需求较多,双向通行隧道驾驶人注视位置更多地在视觉远景和近景间切换。根据通行条件对驾驶人视觉特征的影响,从公路隧道照明设计等方面提出了建议。
A number of highway tunnels in Zhejiang Province are selected to carry out the real vehicle test to study the driver＇s visual characteristics in the interior zone of the one-way and two-way tunnel.The driver＇s viewpoint distribution ratios in the interest region,the area and barycentric coordinates of driving visual search area and other indicators are used to compare the difference in driver＇s viewpoint distribution between the one-way and two-way tunnel interior zone in order to analyze traffic safety impact of one-way and two-way traffic conditions quantitatively.The study shows that horizontal search range of the driving field in two-way tunnel is smaller and longitudinal visual search stability is lower in two-way tunnel.In addition,the demand of switching the viewpoint between left and right is more in one-way tunnel and the driver＇s gaze position switches more between near view and far view in two-way tunnel.Some suggestions on highway tunnel lighting design and other aspects are proposed based on the influence of the traffic conditions on the driver′s visual characteristics.
