摘要:
本文利用变权与信息论中的熵理论对城市快速路节点的重要度进行评价,根据节点的重要度进行城市快速路节点规划.首先,分析城市快速路节点的影响因素,构建城市快速路节点重要度的评价指标.其次,用熵权法构造常权向量,研究评价指标间的相互关系适当选取状态变权向量.再次,应用常权和变权向量构造变权模型,建立城市快速路节点重要度的评价模型.最后,应用实例对快速路节点进行评价,验证了模型的有效性,并提出规划意见.结果表明,此种针对城市快速路节点重要度的评价方法,能考虑到各指标之间的相互影响及指标值波动对实际结果所产生的影响,规划结果符合实际,并且对未来规划提供一定的参考价值,为城市快速路节点的规划与设计提供理论依据.
Abstract:
A new method based on information entropy theory and variable weight theory is used to plan urban expressway nodes in the present research. First of all, theory evaluation index system of urban expressway nodes is established on the basis of influence factors. Secondly, constant weight is established based on information entropy theory and state variable weight vectors are chosen according to the interplay of the influence factors. Thirdly, variable weight is established by using the constant weight and state variable weight vectors. Finally, the model is verified by an example. The results shows that the model based on variable weight could better evaluate the importance of urban expressway nodes and provide a theory for planning and designing urban expressway nodes
