公路改扩建工程是对现有道路通行标准的提升,是在原有道路上的升级换代,公路改扩建的主要目的就是道路更加安全,交通更加流畅,因此往往涉及到路面拓宽、平面交叉口、视距问题、平纵线形与平纵组合等方面,这对于公路改扩建的道路设计又有着诸多的安全问题要加以重视,确保改扩建道路质量一流,安全第一,要做好改造道路的设计,就要首先从安全角度出发,严格规范设计,消除安全隐患,以期在设计阶段就开始重视交通安全,从道路设计角度防范交通事故本文着重对公路改扩建道路设计中的安全问题加以分析研究,希望能够为公路建设提供可靠的参考资料。
The road reconstruction and expansion project is an upgrade of existing road traffic standards. It is an upgrade on the existing roads. The main purpose of road reconstruction and extension is to make the roads safer and the traffic more smooth. Therefore, road pavement extension, flat intersection, The problem of vertical alignment and horizontal combination of vertical and horizontal lines, which for road reconstruction and expansion of the road there are many safety issues to be taken seriously to ensure that the expansion of the first-class quality roads, safety first, we must do a good job in the transformation of the road design, We must start from the safety point of view, strictly regulate the design to eliminate potential safety problems, with a view to begin to pay attention to traffic safety in the design phase, from the perspective of road design to prevent traffic accidents. This paper focuses on road safety in highway reconstruction and expansion of the road to be analyzed, Can provide reliable reference for highway construction.
