摘要
城市公路网的分析与评价对于公路网规划项目开发、实施决策具有重要的理论价值和现实意义.建立了基于加权主成分分析法的公路网综合评价模型,并给出了评价案例.评价结果表明,利用加权主成分分析法评价公路网可以将主成分分析法的客观分析和层次分析法的主观分析有机地结合起来,其评价结果更加全面、更加符合客观实际情况.
The analysis and evaluation for the road network has important theoretic value and realistic significance for the implementation of the road network projects. Comprehensive evaluation model based on weighted principal component analysis for the road network is presented and an example is introduced. The evaluation results show that the weighted principal component analysis model can combine organically the objectivity of principal component analysis with the subjectivity of analytic hierarchy process, so the evaluation results should be more overall.
