在公路网节点层次划分中,一般的做法是根据专家的经验划分层次。由于专家的主观认知角度不同导致节点层次与实地情况出现一定的差异,从而使公路网布局方案出现不合理。针对这种现象,提出综合指标模型在路网节点层次划分中的应用,通过研究区域的社会经济特征,选取影响节点重要性的指标来计算节点综合重要度。根据计算值,初步划分节点层次;再通过对中间层节点的鉴别,确定最终层次。运用该方法对诸暨市所辖27个街道(镇)进行了层次划分,所得结果符合市域城镇体系规划,说明有较好的应用价值。
In the road network node level, the general approach is based on the expert’s experience level. Due to the subjective cognition angle of the experts, there is a certain difference between the node level and the field situation, so that the road network layout plan appears unreasonable. In view of this phenomenon, this paper proposes the application of the comprehensive index model in the hierarchical classification of road network nodes. The comprehensive importance of nodes is calculated by studying the socio-economic characteristics of the region and selecting the indexes that affect the importance of nodes. According to the calculated value, the node level is initially divided; finally, the final level is determined through the identification of the node in the middle level. This method is used to classify the 27 streets (towns) under the jurisdiction of Zhuji, and the results are in line with the planning of urban system in cities and towns, indicating that they have good application value.
