在与驾驶安全相关的因素中，与睡眠相关的变量是导致道路事故的主要原因。驾驶员嗜睡的昼夜节律波动此前曾被认为与道路安全有关。然而，睡眠类型在这种关系中的作用却很少被研究。因此，本工作的目的是解决驾驶性能是否受到昼夜节律模式的影响，而昼夜节律模式又受到驾驶员的生物钟类型和一天中的时间的调节（即同步效应）。我们在早上和晚上的几次模拟驾驶课程中评估了 47 名具有特定睡眠类型的健康年轻人。我们收集了驾驶表现数据，以及每次驾驶前自我报告的激活水平和其他与睡眠相关的变量。当测试时间超出一天中的最佳时间时，参与者的驾驶安全性会降低，这取决于他们的生物钟类型并由自我报告的激活水平证实。这些差异在早晨更为明显，此时早晨型汽车表现出更好的驾驶性能。我们的结果表明，睡眠类型在调节一天中的时间与驾驶安全之间的关系方面发挥着重要作用。因此，有必要在驾驶行为的理论模型中承认这一变量，并改进职业事故预防计划。
Among the factors associated with driving safety, sleep-related variables constitute a leading cause of road accidents. Circadian fluctuations of driver's somnolence has been previously linked to road safety. However, the role of chronotype in this relationship has been poorly investigated. Thus, the aim of the present work was to address whether driving performance is influenced by circadian patterns, in turn modulated by the driver's chronotype and the time of day (i.e. synchrony effect). We assessed 47 healthy young adults with specific chronotypes in several simulated driving sessions, both in the morning and in the evening. We collected driving performance data, along with self-reported levels of activation prior to each driving session and other sleep-related variables. Participants drove less safely when testing times took place outside their optimal time of day, as determined by their chronotype and confirmed by self-reported levels of activation. These differences were more pronounced in the morning, when morning types shown a better driving performance. Our results suggest that chronotype plays an important role as a modulator of the relationship between the time of day and driving safety. Therefore, it is necessary to acknowledge this variable in theoretical models of driving behavior, and for the improvement of occupational accidents prevention programs.
