With the acceleration of urbanization and the continuous increase of vehicle ownership,traffic congestion and traffic pollution are becoming more and more serious.National government,domestic and foreign scholars pay more attention to solving traffic problems.The use of urban traffic microcirculation to share urban trunk roads to promote green travel while not affecting the daily lives of residents in residential areas has become the focus of current research.To solve the city traffic problem from the source,there is also a need to live together the efficiency of traffic microcirculation and urban street network form,analysis of the internal relations,to find the vehicle and slow traffic integration breakthrough,realize the healthy and orderly development of city traffic.In this paper,the research status at home and abroad as the foundation,analyzes the principle and characteristics of the definition of traffic microcirculation,residential traffic theory,characteristics,functional structure,spatial form and characteristics,construction of residential traffic microcirculation efficiency evaluation system,using AHP to determine the index weight.Residential area of Chengdu city were selected in different directions and construction mode of investigation and data,questionnaire investigation to verify the reliability of live weight evaluation area traffic microcirculation efficiency,understand the selected residential area composed of traffic microcirculation level and index.According to the residential index data were analyzed to determine the correlation between indicators,combined with the relevant national standards,using linear regression to establish the regression equation between the index to calculate the index of ideal value analysis method,and as a critical value in accordance with the form and layout of the road network traffic operation management mode and development mode of residential residential classification and the analysis of influencing factors of residential traffic microcirculation efficiency.From the optimization of road network layout form,promote car and slow traffic,building blocks for compatible open residential district,traffic coordination,and improve land use landscape network continuity and other aspects of the street network optimization strategy.The fairy tree settlements for example,evaluating the present situation,proposed the opening residential district,calming design,cross section optimization strategy,and optimize the evaluation,to provide reference for street network optimization based on traffic microcirculation. |
