Simulation Research On The Impact Of Closed Courtyard-style Community Layout On Urban Microcirculation Traffic

Ever since the second-half of last century,the process of urbanization has been faster and faster all around the world.At present,under the comprehensive background of reform and opening up as well as social transformation,traffic demand is increasing,and urban traffic problems are more and more conspicuous,which have become the most important strategic problems.Due to the long-standing restrictions caused by planning idea and management system,there are many large closed communities such as schools,hospitals,military areas,factories and residential areas in the city for a long time.To some extent,the formation of urban micro-circulation road network is prevented by these closed communities,which make the urban traffic cut off and the pressure on urban road network increased.Combined with closed courtyard-style community and the urban traffic microcirculation,the impact of the layout of closed courtyard-style community on the urban traffic micro-circulation is studied in this paper,which can help explore the different types of urban traffic microcirculation network for different cities and promote the development of urban traffic ultimately.Some aspects are included as follows:Firstly,based on the forming history and development of the enclosed courtyard-style community,the strengths,weaknesses and developing trend are studied.Secondly,the features and existing problems of the urban traffic micro-circulation are studied by analyzing the operation mechanism.Thirdly,combined with the survey data and the practical situation of Zhangdian District of Zibo City,traffic simulation and analysis for the impact of the layout of closed courtyard-style community on the urban traffic micro-circulation are conducted by making use of TransCAD and Vissim.
