Research On Collaborative Passenger Transportation Capability Of Multi-mode Public Transportation Network And Its Improvement Method

In order to improve the efficiency of passenger transport and alleviate traffic congestion,this paper discusses the collaborative relationship between multi-mode public transport network and passenger transport capacity, and puts forward the methods of improving passenger transport capacity.This paper analyzes the structure characteristics of conventional public transport,BRT and metro network,discusses the topology structure of multi-mode public transport network,and analyzes the relationship between three types of network coordination and passenger transport capacity.The spatial and temporal distribution characteristics of network passenger flow are analyzed through big data.According to multiple nonlinear regression analysis and residual analysis,a"two factor transport capacity coordination model" is proposed to calculate the capacity of multi-mode public transport network.Through computer programming and software redevelopment,this paper puts forward the method of passenger capacity improvement based on Voronoi gravity equilibrium model and formulates improvement measures.The passenger capacity is used to evaluate the improvement effect,and Hangzhou is taken as an example.It is found that there are a large number of ring structures in the multi-mode bus network topology,which are mainly formed by network collaboration.The capacity of multi-mode busnetwork of BRT and metro is higher than that of BRT and metro.The average node strength follows the Gauss distribution.The ratio of node size to node strength is less than 1.and the network passenger capacity increases.When the ratio of node size to node strength is greater than 1,the passenger capacity decreases.The connection point of network coordination is affected by the city level and hub scale,and should be set near the large passenger flow transportation station.The statistical characteristics of multi-mode bus network node strength are related to the flow distribution,which follows the Qifu law and has a goodness of fit of 0.98.The passenger capacity calculated by the "two factor transport capacity coordination model" can truly reflect the operation status of transport stations and networks.Node saturation or station modification.The distribution results of Voronoi gravity equilibrium model can guide the improvement of passenger capacity with remarkable effect.The improvement method has been successfully applied in Hangzhou.In order to improve the effect,cost and efficiency,the passenger capacity improvement method proposed in this paper can guide the transformation of existing multi-mode bus network.
