Evaluation of Highway Alignment Consistency Based on the Gray Theory
摘要
Abstract
Alignment consistency is one of the most elementary rules of highway alignment design, and alignment consistency evaluation is the important basis for improving highway alignment. For the shortage of current assessment method, this paper selected the 85th maximum speed reduction, unit speed relative difference |VR| and vehicle acceleration |a|as indexes, and introduced the gray theory into alignment consistency evaluation and established a comprehensive gray evaluation model of the alignment consistency. At the same time, the model was applied to the relevant road sections from Ningan to Fuxing of Hegang-Dalian Highway, and the results were compared with the traditional evaluation method, showing that the application of this method was reliable and accurate.关键词
