摘要
为了研究自由流状态下驾驶人在山区高速公路直线段和曲线段的驾驶行为特性,在西汉高速公路秦岭段进行了实地勘测试验,获得了65个路段的连续车速数据,对车辆在山区高速公路直线段和曲线段的车速控制行为进行了分析.研究结果表明,山区高速公路直线段和曲线段的驾驶人车速控制行为明显有别于平原区高速公路,应针对不同线形路段设置不同的诱导标志,以利于驾驶人的安全行车.
In order to study the characteristics of driving behavior under free-flow conditions of the straight and curve section in the mountainous freeway,continuous speed measurement test was conducted in 65 sections in Xihan freeway,then it was analyzed through the straight and curve section.The results show that the speed characteristic of the mountainous freeway is different from that of the normal freeway.Different induction signs should be set according to different types of road alignment which will help the driver drive safely.
