摘要: 为明确高速公路小净距“隧道-互通”路段下匝道驾驶人心理负荷水平,通过实车驾驶试验采集33名被试者在渝湘高速黄草互通至保家互通的心电数据,分析驾驶人心率增长率均值、心率增长率最大值、R-R间期(心电图相邻R波之间的时间间隔)标准差和连续R-R间期均方根的分布特征,以此为观测变量构建基于因子分析法的心理负荷综合量化模型,揭示小净距“隧道-互通”心理负荷水平,以及其与常规隧道、常规互通的差异,探讨隧道与互通之间的净距及驾驶人因素的影响。结果表明:4处小净距“隧道-互通”的驾驶人心理负荷分别分布在0.23~1.00、0.00~0.87、0.15~0.76和0.03~0.65,显著高于常规隧道( p<0.05);净距在410 m及以下的3处小净距“隧道-互通”的心理负荷显著高于常规互通出口(p<0.05);随着净距的减小,心理负荷逐渐增大,且心理负荷在两两小净距“隧道-互通”路段之间均存在显著性差异(p<0.05);不同类型驾驶人之间心理负荷差异显著(p<0.05),女性驾驶人心理负荷比男性高41.0%,不熟悉路线的驾驶人比熟悉型心理负荷高37.8%,非经验型驾驶人心理负荷比经验型增加59.0%。

Abstract: To quantify the mental workload of drivers in closely spaced tunnel-interchange sections on diverging freeways, electrocardiogram data of 33 participants were collected through on-road driving tests along the Huangcao to Baojia Interchange section of Chongqing-Hunan Expressway. The distribution characteristics of the mean heart rate increasing rate, maximum increasing rate of heart rate, standard deviation of R-R intervals (the time intervals between adjacent R waves on the electrocardiogram) and root mean square of continuous R-R intervals of drivers were analyzed. A comprehensive quantitative model of mental workload based on factor analysis method was constructed through using these indicators as observation valuables. The mental workload level of the closely spaced tunnel-interchange section and its differences between general tunnel and interchange were revealed. The influences of clearance distance and driver factors on the mental workload were discussed. The results show that the mental workload of the four closely spaced tunnel-interchange sections ranges between 0.23~1.00, 0.00~0.87, 0.15~0.76, and 0.03~0.65 respectively, which is significantly higher than that of the general tunnel ( p<0.05). The mental workload of the closely spaced tunnel-interchange sections with clearance distance of 410 meter or less is significantly higher than that of the general interchange ( p<0.05). As the clearance distance decreases, the mental workload gradually increases. There are significant differences in mental workload between each pair of the closely spaced tunnel-interchange sections ( p<0.05). There are also significant differences in mental workload among different types of drivers ( p<0.05). The mental workload of female drivers is 41.0% higher than that of male drivers. The drivers who are not familiar with the route have a 37.8% higher mental workload than those who are familiar with it, and non-experienced drivers have a 59.0% higher mental workload than experienced drivers.
