线形连续是高速公路线形设计最基本的要求之一，线形连续性评价是高速公路线形调整改善的重要依据。本文针对现有评价方法的不足，选取单车车速差85MSR、单位速度相对差|RV|、车辆加速度|a|等评价指标，并将灰色理论引入到连续性评价中来，建立了线形连续性灰色综合评价模型。同时，将模型运用于鹤岗高速相关路段，并与传统评价方法的评价结果进行了对比分析，表明应用该方法是可靠的、准确的。
線形連續是高速公路線形設計最基本的要求之一，線形連續性評價是高速公路線形調整改善的重要依據。本文針對現有評價方法的不足，選取單車車速差85MSR、單位速度相對差|RV|、車輛加速度|a|等評價指標，併將灰色理論引入到連續性評價中來，建立瞭線形連續性灰色綜閤評價模型。同時，將模型運用于鶴崗高速相關路段，併與傳統評價方法的評價結果進行瞭對比分析，錶明應用該方法是可靠的、準確的。

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.
