摘要
由于受公路技术等级、功能差异和地区经济发展不平衡的影响,传统连通度和模糊连通度的计算方法很难真实反映区域公路网的连通状况.基于公路适应交通量、公路重要度和节点重要度对连通能力的影响进行分析,分别对节点连通度和网络连通度的定义做新的描述,提出区域公路网连通度的计算模型.通过实例表明,考虑连通能力的区域公路网连通度计算模型不仅能真实反映区域公路网的结构性能,而且还可以对节点连通度进行排序,深化了连通度的内涵,有助于为区域交通规划提供决策参考.
For the influence of road technical grade, function difference and development imbalance of the regional economic, the algorithm method of traditional connectivity and fuzzy connectivity are improper in reflection connectivity of regional road network. Based on the detailed analysis of the connectivity capacity which is caused by road traffic volume, road importance and node importance, the new definition of node connectivity and network connectivity is described respectively, and the model of the regional road connectivity is brought too. Through the given examples, the new model can reflect the real frame capability of the regional road network, and it can also take the order according to the size of the node connectivity. So it extends the meaning of connectivity, and can offer choices for regional traffic planning.
