| 摘 要： | 为了量化交通拥堵对驾驶人生理和心理特性的影响,选取驾驶人的心率均值为指标,在大量实测数据基础上研究交通拥堵程度对驾驶人心率特性的影响,并构建心率均值和压力系数间的关系模型。研究表明,交通拥堵对驾驶人的心率特性影响显著,3种回归模型拟合优度的确定系数都达到了0.6以上,且二次多项式的回归效果最好。

| Abstract: | Transportation infrastructure scale is constrained by many factors ,due to the limited space of the cities . Traffic congestion will affect people＆#39;s daily life in a long time with the rapid increase of vehicle population .The mean heart rate is selected as an indicator to quantify the impact of traffic congestion on the driver＆#39;s physiological and psychological status .Moreover ,the impact of traffic congestion level on the driver＆#39;s heart rate characteristics is studied based on a large number of measured data .In addition ,the relational model between mean heart rate and pressure coefficient is estab-lished .Research shows that the effect of traffic congestion on heart rate characteristics is significant ,and that the deter-mination coefficient of the goodness-of-fit of the three regression models can be above 0 .6 with the best regression result of the quadratic polynomial .The results can provide a theoretical support for the efficiency and safety evaluation of traffic congestion . |
