基于权重调整的公交网络效率研究
Research of weight adjustment on the efficiency of transit networks
摘要
Abstract
Efficiency of transit networks is often critical to the operations of urban transportation.Transport efficiency between any bus stations and that in the transit network are both on the relation between the part and the whole.How to improve the efficiency of the whole tran.sit network by adjusting local efficiency is a very important research project.Bus station network is scale-free network.Link weight is the travel time between any stations.Therefore,the adjustment of weight becomes one of the methods to improve the efficiency of public transport network.From the perspective of network,the effects of weight distribution on the scale-free networks efficiency are investigated.The results demonstrate that exponential distribution of link weight shows significant improvement to the efficiency of transit networks in both global and local.This paper could provide a new guidance for the optimization of public transport network,through the role of weights in scale-free network is verified.关键词
