高原长平直线公路汽车行驶安全

Driving safety on long-even-straight-line road on highland

为了降低高原公路长平直线路段交通事故率,以实地调查和心理认知机理,对国道213线郎木寺至川主寺公路长平直线路段的车辆行驶安全性进行研究,分析了驾驶人在长平直线路段上行车的交通安全认知及行为特性。研究表明:该路段上交通事故多发的主要原因是道路景色单调,高原反应使驾驶人容易疲劳、反应迟钝;道路两侧缺乏明显的参照物,驾驶人对速度判断的准确性受到影响,容易超速行驶;经常有牧群横穿道路,产生横向干扰。通过对长平直线路段的道路景观设计、路肩设置隆声带、路面喷涂视觉减速标线以及在适当的位置设置放牧通道等安全措施,可提高高原长平直线路段的汽车行驶安全性。

In order to decrease the traffic accidents on long-even-straight-line road on highland, taking the section of the National Highway 213 from Langmusi to Chuanzhusi as an example, the influencing factors on driving safety on this kind of highway were studied. It was found that the main reasons causing the accidents are the monotonous scenery along the highway, the plateau reaction of drivers, the lack of accurate judgment for speed of driver, and the disturbance of animals crossing from one side of the highway to another side. It is believed that the reasonable design of landscape, the settlement of noisy belt on the shoulder of the highway. The installation of slowdown stripe on the surface of highway, and the construction of corridors under the highway at appropriate location can reduce the accidents remarkably. 2 tabs, 2 figs, 8 refs.
