Research and Simulation of Node Importance in Transport Network based on Weighted Model
In recent years,studies on network theory have attracted a growing attention,especially,it has become a hot issue to combine the theoretical approach of network with the practical problems.In this paper,we present a new weighted model for public transport network based on network efficiency.Distinguishing from traditional network analysis method,this model considers comprehensively the impact of spatial distance,traffic flow and congestion coefficient on transport network.Then,on the basis of this weighted model,evaluation of node importance is further introduced by method of removing node.Finally,we also carry out computer simulations on this model,an illustrative example is presented to demonstrate the validity of our models and methods.Simulation results prove that our methods are efficient and reliable for analyzing network characteristics and distinguishing the node importance.
