Research On Community Opening And Road Traffic Impact Based On Entropy Weight Algorithm

With the gradual advancement of China's economic development and urban construction,urban road congestion is common in major cities.In order to alleviate traffic pressure and continuously build large-scale transport mfrastructure,the fundamental reason is that land use planning and traffic planning are not considered systematically,which leads to wider urban roads and more congested traffic,thus restricting people's walking accessibility.Therefore,this paper mainly studies the community management mode of urban space,realizes the interaction with traffic network,and alleviates urban traffic congestion.In order to achieve the research objectives,this paper focuses on several research work:This paper interprets and analyzes the relevant theories and current status of community openness.Through the interpretation of the closed community and open community theory,we can understand the development trend of the current community management model construction in China.Comparing the development status of open communities at home and abroad,it is concluded that China is currently in the initial stage of development in the open community management model.The specific open model is still immature and analyzes its main reasons.Secondly,the on-site investigation method and interview investigation method were used to investigate the community area,vehicle status and road type,and the questionnaire was used to investigate the community population and living area.Organize and analyze the collected data to lay the foundation for the quantitative analysis of the impact of community openness on traffic.Then,the entropy weight algorithm is used to establish the mathematical model of community opening impact on traffic,and the weights of geographic location,community area,population density,vehicle status and road type are calculated.The entropy weight method is used to evaluate the five factors.Community change,then compare the traffic volume before and after the community is opened.Finally,the community in the vicinity of the South Third Ring Road in Xi'an was selected as the research object.The entropy weight algorithm model was used to calculate the weight of each factor,and the traffic volume inside and outside the community was calculated to compare the impact of the community on road traffic before and after opening.It was finally determined that the " big open,small closed”group-based community model is the development direction of Xi'an community opening,and provides reference for Xi'an residential community construction.
