摘要: 为预防由认知分心影响驾驶人应激反应能力引发的交通事故,开展试验,在驾驶模拟器平台上模拟城市、乡镇、山区和高速公路等应激场景,测试有无分心任务2种条件下驾驶人的应激反应,采集驾驶人操作数据和车辆行驶数据,并利用Facelab5型眼动仪记录驾驶人眼动数据;选取相关表征指标并分析试验数据。结果表明:相比于正常驾驶,认知分心驾驶导致驾驶人视觉搜索范围变窄;无论正常驾驶还是认知分心驾驶,扫视行为均以中、低幅度为主;认知分心导致驾驶人对加速踏板的控制能力减弱;与正常驾驶相比,认知分心时驾驶人的应激反应时间明显增加。

Abstract: For the sake of preventing traffic accidents cognitive distraction may caused experimental trials were carried out to test the drivers' stress response under the two conditions: normal and cognitive distraction driving conditions.A driving simulator platform was used to simulate various stress scenarios such as city,town,mountainous area and highway,and collect driver operating data and vehicle driving data.A Facelab5 eye tracker was used to record the driver's eye movement data.The related characterization indicators were selected.And the experimental data was analyzed.The results show that compared with normal driving,cognitive distraction driving leads to a narrower visual search range for drivers.For both normal driving and cognitive distracting driving,the scanning scope is mainly medium and low.Cognitive distraction weakens the driver's ability to control the accelerator pedal.Compared to normal driving,cognition distraction increases significantly the driver's stress response time .

Key words: traffic accidents, cognitive distraction, stress response, eye movement data, driving behavior, simulated driving
