区域公路网规模预测研究

Research on Scale Forecast of Regional Highway Network

公路网规模预测是区域公路网规划的重要内容。通过分析公路网规模的主要影响因素和现有的公路网规模预测研究方法,分析了因素分析法中常用的国土系数法存在的不足,并结合杭州市具体情况,提出了国土系数法的改善方法。建议根据具体实际综合分析公路网系数,通过改进公路网系数的计算模型,得到更准确的公路网规模预测值。

The scale forecast of highway network is an important part of the regional highway network planning.By analyzing the primary influence factors and usual research methods of the scale of highway network,one of the factor analytical method-the territory coefficient method is appraised,and illustrated by Hangzhou,the melioration of this method is proposed-analyze the highway network coefficient according to the regional specific condition,to get more accurate predicted value of the scale of regional highway network via improved computation module of the highway network coefficient,and provide the basis for the regional highway network planning.
