解析车速与线形之间的相关性

Analyticity of Relativity between Driving Speed and Alignment

该文对车速与线形之间的相关性进行了解析。线形是公路的骨架,其设计质量的好坏将直接影响工程造价及运营阶段的使用质量。车速则是线形几何设计的基本控制参数。车速是对线形设计效果最直接的反应,用其来检验及评价线形具有一定的可靠性,因此国内外大多将其作为线形评价的一个参数。但是车速对线形的敏感性是有一定范围的,即车速作为线形评价参数是有一定适用范围的。

The article analyzes the relativity between the driving speed and alignment.The alignment is the skeleton of the highways.Its design quality will directly influence the engineering construction cost and the use quality in the operation period.The driving speed is the basic control parameter of the geometric design for alignment.The driving speed is the most direct reaction to the design result of the alignment,which has some reliability to inspect and evaluate the alignment.Therefore,it is a parameter to mostly use for evaluating the alignment at home and abroad.But the sensitivity of the driving speed on the alignment has some range,that is.the driving speed taken as the alignment e- valuating parameter has some suitable range,
