基于多层矢量网络评价指导的高效交通规划

High Efficient Traffic Planning Based on Guidance of Multi-Vector Network

研究交通规划方案的效率优化问题。传统的交通规划方案采用交通网络节点等价加权的方法,无法反应出不同节点的重要性,并且采用局域化的思想,无法达到全局效率的最优;提出一种基于多层矢量网络评价指导的高效交通规划方法,采用多层矢量网络将交通网分为多个层次进行研究,对不同的层次进行不同加权,以全局效率最优为目的,通过评价指导达到全局最优;最后采用一组10节点的交通网络进行规划实验测试,结果显示,改进的交通规划方法使交通系统的效率远高于传统最优效率,并具有很好的工程应用价值。

The optimization of traffic planning efficiency was investigated in the paper. In traditional method, each traffic network node is weighted with equivalent method, which cannot reflect the different importance of the transportation nodes, and the idea of localization is taken out, so the global optimum efficiency cannot be reached. A high efficient traffic planning method was proposed based on the guidance of multi vector network. According to the multi vector network traffic, the traffic network was divided into muhilayer to be researched, so different nodes were weighted separately. The global optimal efficiency was taken as target and achieved with guidance. At last, a team of 10 nodes traffic network was selected to process experiment. The result shows that with the improved method, the highest system efficiency was improved to 78%, and the lowest efficiency was improved to 63%, which is 50% high er than the traditional method, so it has good application value.
