摘　　要：公路网密度和公路技术等级是公路网规划中分析区域公路网发展水平常用的指标,然而单独使用这些指标不能全面反映区域公路网规模和结构的合理性。针对公路网密度和技术等级指标的不足,提出一种基于公路网密度等级比的分析指标,利用山西省各地市统计数据对比分析相关指标。最后利用山西省历年数据建立模型,并利用模型预测分析发展趋势。The highway network density and highway technical grade are common indexes for analyzing the development level of regional highway networks in highway network planning,however,a single index cannot comprehensively reflect the rationality of the scale and structure of the highway network.Focusing on the deficiencies of the highway network density and technical grade,this paper proposes an analysis index based on the density ratio of the highway network,which uses the statistical data of cities in Shanxi Province to compare and analyze relevant indexes.Finally,a model is established by the data from Shanxi Province over the years to predict and analyze the development trend.

关 键 词：公路网密度 公路技术等级 公路网发展水平 公路网密度等级比
