目的.采用驾驶模拟器对同向偏盲（HH）驾驶员选择增加盲侧安全裕度的车道位置的假设进行了验证。12名HH参与者（6名右侧HH和6名左侧; 9名男性;平均年龄50岁;范围31-72）和12名匹配的视力正常（NV）的当前驾驶员每人完成了约120分钟的模拟器驾驶。车道位置和转向稳定性进行了评估，为特定的路段类型（直线段，曲线，转弯）在城市和农村的无分隔公路驾驶。右侧HH的驾驶员在直线路段上的车道位置显著（P = 0.001）在NV驾驶员的左侧，在曲线上的车道位置在较小程度上。左侧HH驾驶员在直道和弯道上的车道位置与NV驾驶员相似，但在左转时遵循的车道位置明显（P = 0.005）更长。研究结果支持这一假设，即驾驶员与HH采取的车道位置，增加了安全裕度在他们的盲侧，但是，绝对车道位置不同的转向操纵和位置的风险，从迎面而来的交通变化与路段类型。（Invest Ophthalmol维斯科学。2010; 51：6605-6613）DOI：10.1167/iovs.10-5310
PURPOSE. The hypothesis that drivers with homonymous hemianopia (HH) would take a lane position that increased the safety margin on their blind side was tested with a driving simulator.METHODS. Twelve participants with HH (six right HH and six left; nine men; mean age, 50 years; range 31-72), and 12 matched current drivers with normal vision (NV) each completed approximately 120 minutes of simulator driving. Lane position and steering stability were evaluated for specific road segment types (straight segments, curves, and turns) in city and rural undivided highway driving.RESULTS. The drivers with right HH held a lane position significantly (P = 0.001) to the left of NV drivers on the straight road segments and to a lesser extent on the curves. The drivers with left HH had a lane position similar to that of the NV drivers on straights and curves, but followed a significantly (P = 0.005) more rightward path on the left turns.CONCLUSIONS. The results support the hypothesis that drivers with HH take a lane position that increases the safety margin on their blind side; however, absolute lane position varies as the steering maneuver and location of the risk from oncoming traffic change with road segment type.
