驾驶中听音乐对驾驶安全的影响

Effects of listening to music during driving on driving safety

为研究听音乐对驾驶安全的影响,选取32位男驾驶人和8位女驾驶人,平均分成4组进行模拟驾驶试验。布置包含道路车流较少和紧急情况的模拟现实的交通场景,安排4组被试分别参加音乐音量测试和音乐节奏测试。基于试验所得数据,分析得出音量、节奏对各组驾驶人的脑力负荷和驾驶行为的影响。结果表明:驾驶人在听音乐时脑力负荷增大,平均驾驶速度增加;随着音乐节奏的加快,平均驾驶速度增加,交通违章次数增加,横向位置控制随之恶化;随着音乐音量的增加,交通违章次数增加;60 dB的音乐有助于横向位置的控制,75和90 dB的音乐会使横向位置控制恶化。

To explore effects of listening to music while driving on driving safety,32 male participants and 8 female participants who averaged into four groups were selected to complete simulated driving tests.Firstly,a traffic scene containing a road with less traffic and emergency setting was input into the control center computer. Secondly,four groups respectively attended a test with music volume being zero,60 dB,75 dB and 90 dB. Lastly,four groups respectively attended a test with no music,slow,middle and fast tempo music. The test results show that drivers listening to music have a heavier mental workload and a faster average driving speed than those who do not listen to music,that a faster music tempo makes both average driving speed and number of traffic violations increase,and lateral position control get worse,that a increased music volume makes number of traffic violations increase,that listening to 60 dB listening to music helps control lateral position,and that drivers listening to 75 dB and 90 dB music have a worse control of lateral position.
