Simulation Of The Busline Complex Network Revolution Considering Land Use Change

There has been a long time since city traffic jams occured,along with the city development and population growth,city traffic situation has became more and more serious.The bus system is an important part of city traffic,meanwhile the growth of city bus system is closely related to land use,so using land use data to research the development progress of the city bus network can give some suggestions to optimize the public transportation network and relieve traffic jams.At the same time,bus system has the typical chartertics of the complex network.,the bus stops and bus lines have much consistency with the node and edge of the complex network.Therefore,the evolution of the transit network using complex network modeling method and traffic travel volume prediction method,taking land use change into account is studied in this paper.The main research works are as follows:(1)Bus line evaluation model establishment considering land use data.The article discussed the relationship between land use and public transport network,especially analyzed the impact of land use type,land use intensity on public transport network and the relationship between land price and public transport network in detail.On the basis of this,the bus line service efficiency model based on land use data is constructed,using which we can evaluate bus line quickly.What’s more,a number of other evaluation indicators of public transport lines such as road assumed coefficient、traffic orbit repetition coefficient、roadline non-linear coefficient are constructed,those indicators lay the foundation for the study of the evolution of public transport network later.(2)Modelling of the complex network of bus line establishment considering land use data.The complexity of transit network was analyzed from the respect of network constructure、node and influence factors of the evolution,and the modeling of the complex network of urban public transport was also carried out.Then,the complex network of bus lines was constructed using land use data as well as bus line evolution indicators,meanwhile the evaluation index is constrainted and limited,the nature and construction algorithm of the evolution model are elaborated,and the algorithm of line adjustment in the evolution progress is explained.(3)The empirical analysis on the evolution of the complex network of bus routes---a case of study of Wuhan.An empirical study on the evolution model of the public transit network was carried out to simulate the evolution process of the public transit network in Wuhan city as a bus line complex network evolution system is built using ArcGIS Engine.The simulation result and network in reality are comparative analyzed using some evaluating indicators of complex network theory.It is found that using land use data to simulate the evolution progress of bus line network is reasonable and effective.The line optimization programs in the simulation results are also comparative analyzed with the busline program in reality,which exposed the defect of Wuhan public transport network such as high repetition in parts of the line sections and low operational efficiency.Based on the traffic problems of Wuhan City,this paper puts forward two suggestions.The model further revealed the relationship of land use and transit network,enriched the public transport network evolution theory in a certain extent,it can provide some reference for planning of the traffic control department and the subsequent bus line network development.
