Traffic congestion is more likely to lead to aggressive driving behavior that is associated with increased crash risks. Previous studies mainly focus on driving behavior during congestion when studying congestion effects. However, the negative effects of congestion on driving behavior may also affect drivers' post-congestion driving. To fill this research gap, this study examined the influence of traffic congestion on driver behavior on the post-congestion roads (i.e., the roads travelled right after congestion). Twenty-five subjects participated in a driving simulation study. They were asked to complete two trials corresponding to post-congestion and non-congestion conditions, respectively. Driver behavior quantified by driving performance measures, eye movement measures, and electroencephalogram (EEG) measures was compared between the two conditions. Ten features were selected from the measures with statistical significance. The selected features were integrated to characterize drivers' response patterns using a hierarchical clustering method. The results showed that driver behavior in post-congestion situations became more aggressive, more focused in the forward area but less focused in the dashboard area, and was associated with lower power of the β-band in the temporal brain region. The clustering results showed more aggressive and lack-of-aware response patterns while driving in post-congestion situations. This study revealed that traffic congestion negatively affected driver behavior on the post-congestion roads. Practical implications for driving safety education was discussed based on the findings from the present study.
交通拥堵更容易导致攻击性驾驶行为，从而增加事故风险。先前的研究主要集中在研究拥堵效应时的拥堵期间的驾驶行为。然而，拥堵对驾驶行为的负面影响也可能会影响驾驶员在拥堵后的驾驶行为。为了填补这一研究空白，本研究考察了交通拥堵对驾驶员在拥堵后道路（即在拥堵后行驶的道路）上的驾驶行为的影响。二十五名受试者参加了一项驾驶模拟研究。他们被要求分别完成两次对应于拥堵后和非拥堵条件的试验。在两种情况下比较了通过驾驶性能指标、眼动指标和脑电图（EEG）指标量化的驾驶行为。从具有统计学意义的指标中选择了十个特征。使用分层聚类方法，将选定的特征整合起来，以表征驾驶员的响应模式。结果表明，在拥堵后情况下，驾驶员的行为变得更加激进，在前向区域更加集中，但在仪表盘区域的注意力减少，并且与颞叶区域的β波段的功率降低有关。聚类结果表明，在拥堵后情况下，驾驶时的反应模式更加激进且缺乏意识。本研究表明，交通拥堵对拥堵后道路上的驾驶员行为产生负面影响。基于本研究的结果，讨论了对驾驶安全教育的实际意义。
