摘要: 为有效提高驾驶员在视距降低时对道路线形变化的感知精度,保障行车平稳与安全,研究道路线形动态诱导标志在弯道上的设置方法。综合考虑道路平曲线几何参数和能见度影响下驾驶员安全行驶视线的要求,构建适应能见度变化的平曲线路段几何方程和行驶视线的几何方程;提出优化诱导标志起始位置及设置间距的计算方法;开展驾驶仿真试验,对比验证方法的有效性。结果表明:通过所提方法设置弯道线形动态诱导标志,车辆在弯道的行驶速度差变化较小、车道偏移量降低、方向盘转角幅度减小。

Abstract: In order to improve the driver's perception accuracy of road alignment changes when the sight distance decreases, and to ensure the driving stability and safety, the method of setting dynamic alignment signs on the road was studied. Considering the geometric parameters of road horizontal curve and the requirement of driver's safe driving sight under the influence of visibility, geometric equations of horizontal curve section and driving sight adapting to visibility variation were constructed, and the calculation method of optimizing the starting position and setting spacing was put forward. The validity of the proposed method was verified by driving simulation tests. The results show that after setting dynamic linear induction signs by the above method, the vehicle speed difference in curved road has little change, the lane offset is reduced, and the steering wheel angle amplitude is reduced.

Key words: visibility, horizontal curve, induction signs, perception accuracy, driving sight
