| 摘 要： | 分析了城市群交通发展的新方式,指出了城市群交通规划中＂四阶段＂模型的缺陷,它不能准确地反应城市发展过程中城市之间的联系程度和交通需求强度。为此,将可达性贯穿于城市群交通规划中,阐述了传统路网可达性的计算方法在城市群规划中的不适用性,提出了基于节点重要度的城市群可达性计算新方法,能比较准确地反应不同阶段城市群内部之间的联系程度,为交通规划提供了一定的参考。

| Abstract: | New traffic development modes of urban agglomeration are analysed, and drawbacks of ＂four stages model＂ are pointed out, which can＇ t reflect the traffic demand between cities. Therefore, the accessibility is proposed to apply in urban agglomeration＇ s traffic planning. The inapplicability of traditional methods is also elaborate＇d, and a new method to calculate the accsibiiity is proposed based on node importarce, which can retlcet the traffic demand among urban agglomeration and provide a reference for traffic planmng. |
