高速公路网络布局的区域适应性评价指标研究

高速公路网是为区域社会经济发展服务的,因此,在进行网络布局评价时需要考虑规划区域社会经济发展水平的差异性。分析了现有的公路网布局评价指标,指出其在路网布局的区域适应性评价方面存在的不足。根据现有的网络布局特征指标和区域社会经济特征指标,提出了网络布局的区域适应性评价指标,使网络布局评价指标体系更全面、合理。最后给出计算示例,说明所提指标的有效性。

A Study on Evaluation Indices on Adaptability Between Expressway Network Layout and Regional Characteristics

Expressway network plays an important role in regional society and economy development,therefore the diversity of regional characteristics should be taken into account as evaluating expressway network layout. In this paper,the existing evaluation indices on highway network layout are analyzed,and the deficiency of those indices on adaptability between network layout and regional characteristics is pointed out.On the basis of the existing network layout indices and regional indices,the indices on adaptability between network and regional characteristics are brought up,which rationalize the existing evaluation indices.Last a calculating example is given,and the validity of the adaptability indices is explained.
