The Study On Carbon Emissions Evaluation System And Valuation Methodology Of Urban Transportation System

With the rapid development of our social economy, urban transportation demand isincreasing, and urban transportation energy consumption and greenhouse gas emissionsare rising year by year. Energy shortage and environmental degradation seriouslyrestrict the development of human society. In this situation, transportation energyconservation and emission reduction are imperative. This thesis researches on thecarbon emissions and the development level evaluation of urban traffic system.On the basis of extensive research and literature reading, the current situation of thedevelopment of low-carbon transport in domestic and foreign cities are reviewed andthe concept of low-carbon transport is summarized; From the perspective of analysis offactors about the urban traffic carbon emissions, the total urban residents travel,transportation share rate, average travel distance and coefficient of carbon dioxideemissions are induced, and urban transportation system of carbon emissions estimationmodel is established; Through fully analysis of urban traffic carbon emission factors, theevaluation index is determined, and the evaluation index system of the urban traffic lowcarbon development level is established. When the level of the urban traffic low carbondevelopment evaluation index system of evaluation is analysed, this study utilizes theanalytic hierarchy process to determine the weight of each evaluation index, and usesthe cloud physics theory to evaluate urban traffic low carbon development level. InHefei, carbon dioxide emissions from cars, taxis, buses are under estimation, and trafficlevel of low carbon development in Hefei is carried on the comprehensive evaluation.
