中文摘要：
目的通过长平直线路段驾驶员心理状态的研究,给出驾驶建议,以降低在该种道路上的交通事故发生率。方法运用动态心电仪、GPS、雷达测速仪等设备,在一段长约27km的长平直线路段上进行2名驾驶员的心理测试实验,通过对实验数据的处理和分析,研究驾驶员的生理特征随车速和时间的变化情况。结果根据大量实验数据,运用最小二乘法拟合取得驾驶员的心率变化曲线等,通过分析,得到了长平直线路段驾驶员心理状态的变化情况。结论在长平直线公路上驾驶员不易产生心理紧张,从而导致警惕性降低、易超速行驶,是形成交通事故的主要原因。
英文摘要：
Aim To study the drivers′ physiological characters on long-even-straight-line road and raie an advice on drive to decrease the traffic accidents.Methods Experiments about two drivers′ heart rate were done on 27km long long-even-straight-line road by using kinetic electrocardiograph（ECG）,geography information system（GPS）,and radar velocimetry,etc.Results Much real and reliable experiment data were gained,and the curve varying with the drivers′ heart rate is fitted by least square.Then,the drivers′ physiological character varied with speed and time was researched through processing and analysis the data.Conclusion Results show that driver isn′t easy to nervous on long-even-straight-line road,and leads to vigilance reduction and overspeed drive,which are the main reason of traffic accidents.These conclusions have some merits in the field of setting up of Human-Vehicle-Road-environment transportation system.
