通道宽度对驾驶员动态视觉和操作行为的影响

Influences of Passage Width on Driver's Dynamic Vision and Operation Behavior

使用眼动仪及车速记录仪记录了5种试验条件下3名驾驶员在驾驶过程中的眼动行为和车速数据,分析了不同通道宽度条件下的车速变化特征、驾驶员眼动特征和操作行为特征。结果表明:随着通道宽度变窄,驾驶员的注视点变近,对障碍物的注意变得集中,且习惯于以左侧障碍物为参照来调整车辆运行状态;通道宽度变窄使驾驶员信息感知阶段时间所占的比例减小,而操作校正阶段时间所占比例增大,且通过条件越差,对驾驶员的刺激越强烈。

Eye movement behavior and vehicle speed datum of 3 drivers were recorded with eye movement tracking device and vehicle speed recorder when driving in 5 test conditions. Vehicle speed variation characteristics, together with driver＇s eye movement and operation behavior characteristics in different passage width were analyzed. Results show that with passage width narrowing down, driver＇s eye fixation points become nearer and they concentrate their attention on obstructions, and the left side obstruction is often used as reference object to adjust vehicle movement states. The time proportion decreases in driver＇s information perception phase while increases in operation adjustment phase. The more difficult the passing condition is, the stronger stimulation the driver gets.
