Globalization has increased the number of road trips and vehicles. The result has been an intensification of traffic accidents, which are becoming one of the most important causes of death worldwide. Traffic accidents are often due to human error, the probability of which increases when the cognitive ability of the driver decreases. Cognitive capacity is closely related to the driver's mental state, as well as other external factors such as the CO concentration inside the vehicle. The objective of this work is to analyze how these elements affect driving. We have conducted an experiment with 50 drivers who have driven for 25 min using a driving simulator. These drivers completed a survey at the start and end of the experiment to obtain information about their mental state. In addition, during the test, their stress level was monitored using biometric sensors and the state of the environment (temperature, humidity and CO level) was recorded. The results of the experiment show that the initial level of stress and tiredness of the driver can have a strong impact on stress, driving behavior and fatigue produced by the driving test. Other elements such as sadness and the conditions of the interior of the vehicle also cause impaired driving and affect compliance with traffic regulations.
全球化增加了公路旅行和车辆的数量。其结果是交通事故的加剧，交通事故正成为全球最重要的死亡原因之一。交通事故通常是由于人为错误造成的，而当驾驶员的认知能力下降时，这种错误的概率会增加。认知能力与驾驶员的精神状态密切相关，以及车辆内部的 CO 浓度等其他外部因素。这项工作的目的是分析这些因素如何影响驾驶。我们对 50 名驾驶员进行了一项实验，他们使用驾驶模拟器驾驶了 25 分钟。这些驾驶员在实验开始和结束时完成了一项调查，以获取有关他们精神状态的信息。此外，在测试过程中，使用生物识别传感器监测他们的压力水平，并记录环境状况（温度、湿度和 CO 水平）。实验结果表明，驾驶员最初的压力和疲劳水平会对压力、驾驶行为和驾驶测试产生的疲劳产生强烈影响。其他因素，如悲伤和车内条件，也会导致驾驶能力下降，并影响对交通规则的遵守。
