【摘要】 本文应用医学上检测人体心电信息的动态心电仪,结合动态GPS等仪器,研究高速公路上在无其他车流影响下驾驶员行车通过平曲线时心率和横向力系数、半径和车速之间的关系。通过行车试验和数据分析,获得了驾驶员行车时心率与横向力系数、半径与车速之间的回归模型。在此基础上,从驾驶员行车紧张性和行车安全性关系出发,定量计算了驾驶员驾车通过平曲线时的安全临界半径;从驾驶员驾龄、对道路熟悉程度出发,定性分析了不同驾驶员驾车时的心理紧张体验和驾车行为。更多还原

【Abstract】 Appling the mobile ECG in medicine and combining the mobile GPS, the paper studies the relation among heart rate of drivers, coefficient of transverse factor, radius and driving speed on the horizontal curve of freeway without other traffic flow. Passing driving test and data analyzing, the model among heart rate, radius and speed are obtained. On this basis, according to the relation steering tenseness and steering safety about drivers, the bound radius are calculated quantitatively for drivers driving passing horizontal curve, and according to drivers driving undergo and to know degree for road, stress experience and driving action for drivers are analyzed.更多还原
