基于重要度区位联合布局法的省际公路布局研究

Layout of roads link provinces based on the layout method combining node important degree with area location

基于传统公路通道规划理论和方法,采用定性与定量相结合的方法,对省际公路布局采用节点重要度区位联合的布局方法,既克服了交通区位理论量化程度差的缺点,也克服了重要度法对于过境交通需求引起的树状路网的附加联络线的确切意义论述不充分的不足。以湖南省与广东省衔接公路布局为例加以论证,取得较好效果。

Based on the traditional road passageway planning theory and method analysis, integrating quantitative with qualitative, the layout method was applied to combine node important degree with area location to the layout of roads link provinces. In this way it not only avoids that the transportation zone method can＇t qualify the data, at the same time avoids that the node importance can＇t make certain that the addition communication line significance caused by transit transportation demand of tree - like road network. Finally, it takes the roads layout between Hunan and Guangdong as an example, and proves that it is reasonable.
