Based On The Sustainability Of Urban Transportation Environmental Impact Assessment

Urban transport system own is a huge complex with the outside system.Urban transportation planning system for the city's natural,environmental,social and economic and other transportation-related activities bring different degrees of impact,need comprehensive,systematic approach to the impact of urban transport planning to bring to judgment and evaluation,through these evaluations method to determine the fairness and efficiency of urban transport planning programs.However,due to domestic and international traffic in the study of environmental impact assessment of the technical aspects of planning still lacks a comprehensive strong support.Therefore,to achieve sustainable development of urban transport,search technology theory applies to traffic evaluation methods,a research environment impact assessment method need to solve the traffic problems.Based on the above background,in-depth study of the results of the environmental impact assessment method of urban traffic at home and abroad,the paper presents an objective analysis hierarchy process(AHP),data envelopment analysis (DEA) and intergenerational equity method of obtaining combining the three integrated Method binding.Thesis first evaluation of the theoretical basis of the environmental impact of transportation and domestic and foreign research and examples for detailed study and analysis;then,select index parameters according to the theoretical basis,and analysis the influencing factors of traffic environment,index system in line with this article.By determining how urban transport planning and sustainable urban environment "Input-Output" development of a number of input data and indicators of the reference amount,in order to develop a sustainable development of the transport system effectiveness evaluation step.Finally,through a comprehensive integrated analysis method AHP,data envelopment analysis and intergenerational equity combination,its essence,to its dregs.Modeled by entropy method to take the weight of method,after the conclusion of these three methods of comprehensive evaluation,the final summary obtained Sustainability Transport Planning Environmental Impact Assessment.Select the text as a case study of C hongqing C ity,analysis and evaluation of the environmental impact of its transport planning,according to the Chongqing City traffic system current situation,to build Chongqing evaluation system,and for a variety of methods,from different angles,respectively,and various subsystems coordinate of their mutual relationship between the comprehensive evaluation,Chongqing next urban transport system to provide data on the basis of sustainable development.Through the Chongqing case analysis,and achieved good results,demonstrating a comprehensive integrated assessment method presented in this paper is a workable.
