Study On The Optimization Of Road Design For Small Towns In The Urban Area Of Chongqing

The metropolitan area of small towns in the road design is reasonable,directly affect after the completion of the project can meet the needs of urban area in the construction of small towns and local people travel,affect the quality of the project,the project cost and operation condition,related to whether the project can achieve the desired effect,and ultimately decide the path of the social economy benefit.Therefore,it is necessary to evaluate and select the alternatives.But only in the traditional economic and financial evaluation schemes,ignoring the environmental and social aspects,is not fully reflect the road design scientific and rational urban area;small town road design should be based on the original economic evaluation,financial evaluation,comprehensive consideration of the effects of small town road design scheme the environmental and social aspects,analyzing the advantages and disadvantages of different schemes,and whether there are optimized space,thus forming the overall optimal scheme.Based on the actual cases of Wubao town road along the river,conducted a comprehensive analysis on the problem of optimizing the urban area of small town road design,combined with the characteristics of Chongqing urban area of small towns in the system,analyzing the main factors affecting the small town road design scheme,and put forward the main content of comprehensive evaluation includes four respects of technology evaluation,economic evaluation,environmental evaluation and social evaluation,using fuzzy AHP and multi-objective decision principle,using the relative membership degree theory and system fuzzy optimization theory,established a comprehensive evaluation index system,which lays the foundation for comprehensive evaluation of small town road design methods of work in urban area of the standardized procedures,for the further research on the small town road on the social,environmental and economic efficiency To create the conditions for the effect of Yi;through comprehensive analysis and evaluation of Chongqing Jiangbei the Wubao town road along the river design system using fuzzy optimization theory model,the establishment of a multi-level multi-objective decision system of road design scheme of the fuzzy optimization theory model,through analysis and evaluation,optimization and reconstruction of the original scheme,the formation of a more reasonable new programs.
