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。
為瞭量化交通擁堵對駕駛人生理和心理特性的影響，選取駕駛人的心率均值為指標，在大量實測數據基礎上研究交通擁堵程度對駕駛人心率特性的影響，併構建心率均值和壓力繫數間的關繫模型。研究錶明，交通擁堵對駕駛人的心率特性影響顯著，3種迴歸模型擬閤優度的確定繫數都達到瞭0．6以上，且二次多項式的迴歸效果最好。

Transportation infrastructure scale is constrained by many factors ,due to the limited space of the cities . Traffic congestion will affect people'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's physiological and psychological status .Moreover ,the impact of traffic congestion level on the driver'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 .
