沙漠公路交通安全设施优化

通过对塔克拉玛干沙漠公路交通安全影响因素的分析,结合新疆第二条沙漠公路阿拉尔至和田沙漠公路的特点及交通安全设施设置情况,对阿和沙漠公路的标志、标线、护栏、景观带及平面交叉口等方面进行了优化,提出了在沙漠公路上每隔一定距离设立限速标志牌,提醒司机控制车速,谨慎驾驶;增设景观带,缓解司机的视觉疲劳,改善心情,提高行车安全性;改变部分标志牌颜色,增强警示作用;设置纵坡预告标志和下坡标志,提供纵坡信息;设置柱式轮廓标,方便司机确认行驶区域;对交通量较大的交叉口按照统一的标准进行交通安全工程设计及交叉口渠化等优化措施。

Optimization on Traffic Safety Facilities of Desert Highway

Highway signs,lines,guardrail,the landscape belt and intersections of Alaer-Hetian Desert Highway are optimized through the analysis of Takelamagan Desert Highway traffic safety factors and combining the characteristics and safety facilities built of Alaer-Hetian Desert Highway.On the basis of the above,the optimization measures on safety facilities of Alaer-Hetian Desert Highway are put forward,such as the establishment of the speed limit signs at a certain distance to remind drivers to control the speed and cautiously driving;additional landscape to ease drivers visual fatigue to improve mood and enhance traffic safety;changing color of some signs to enhance warning;installed longitudinal slope notice signs and downhill signs to provide the longitudinal information;installed pole contour marking to facilitate the driver to identify moving regional;based on unified standards for safety engineering design and traffic channelization design for complex intersections.
