The inefficiency transportation modes had caused the negative influence on environment. It has caused serious problems not only in traffic jam, but also in discharging a large number of air pollutants. According to the estimation of Taiwan Environment Protection Administration (EPA), there are 42.08% air pollutants originated in vehicle emission, in which 16.97% caused by motorcycles and 24.83% are caused by automobiles. Under the awakening of environmental protection by the gerneral public, the problems in air pollution and energy consumption caused by traffic activities are more and more crucial, and simultaneously, they have become the goals that environment protection and transportation authorities are devoted to improvement. The white paper of transportation strategy of various cities has specifically noted that the keys of transportation strategies are the development of public transportation and the increase usage of public transportation. Under this objective, using low cost and easy application of dedicated bus lane strategies to allivate traffic jam and then restrain the growth of automobiles, is one of the promising alternatives. In the past, researches in dedicated bus lane are mostly focused on capacity analysis, safety evaluation, travel time improvement, and service level assessment; however, there is a lack of estimation in the aspect of environmental benefits. In the sense of sustainable development of urban environment, it’s worthy to compare and estimate the effects of dedicated bus lane on energy consumption and pollution discharge, and on shifting private modes to bus system. We establish estimation model to analyze energy consumption and pollution discharge with and without implementing dedicated bus lane. In addition to estimate the effects of dedicated bus lane on the fuel consumption and pollution discharge, we have also explored the environmental benefits of for whole city area with implementation of dedicated bus lane. In the numberical analysis, we take Taipei as an example while different scenarios are assumed in terms of single bus route, bus corridor, and overall system. For the single bus route case, it was found that fuel efficiency can be increased to 20.87% while emissions of CO, HC, and NOx are reduced by 16.26%, 11.4%, and 8.22%, respectively. For the overall system level, although the benifts of dedicated bus lane are comparatively less due to existing high usage of automobiles, it is still found that daily fuel consumption of bus system can be reduced about 4.48% after implementing dedicated bus lane in Taipei. This implies a total amount of US$14 million saving in fuel cost per year. The emission reductions of CO, HC, and NOx are mearsured as 3.98%, 3.16%, and 2.59%, respectively. This research has also verified that the environmental benefits will be remarkably increased when the network of dedicated bus lane is expanded.第一章 緒論 1 1.1研究緣起 1 1.2研究目的 2 1.3研究方法 3 1.4研究內容及流程 4 第二章 文獻回顧與評析 6 2.1永續發展的意義 6 2.2公車專用道在國內外之運用及成效 8 2.2.1國外實施公車專用道之成效 8 2.2.2台北市之實施經驗 8 2.3機動車輛對能源消耗與空氣污染的影響 14 2.3.1交通運輸與污染之關係 14 2.3.2機動車輛污染排放影響要因分析 16 2.3.3交通運輸與能源消耗之關係 19 2.3.4機動車輛耗油影響要因分析 21 2.4能源消耗與污染排放模式探討 24 2.4.1空氣污染排放量評估模式 24 2.4.2聯合交通模式及污染排放模式討論 28 2.4.3行車耗油模式探討 29 2.5綜合評析 32 第三章 公車運行特性分析 33 3.1公車運行特性 33 3.1.1公車專用道 33 3.1.2一般道路 34 3.2資料分析 36 3.2.1公車行車特性 37 3.2.2 公車專用道上公車於站區之運行軌跡圖 46 3.3公車運行特性與能源消耗、污染排放之關係 49 3.4綜合評析 50 第四章 模式構建 51 4.1基本假設 51 4.2模式構建 52 4.2.1基本思維 52 4.2.2公車耗油模式 56 4.2.3污染排放模式 61 4.3私人運具之能源消耗與污染排放推估 68 4.3.1私人運具之能源消耗推估方法 68 4.3.2私人運具之污染排放推估方法 70 4.4運輸走廊能源消耗與污染排放量之評估 72 第五章 數值實例應用分析 74 5.1參數分析 74 5.2實例分析 78 5.3敏感度分析 85 第六章 結論與建議 92 6.1結論 92 6.2建議 94 參考文獻 95436379 bytesapplication/pdfen-US能源效率公車專用道空氣污染Energy EfficiencyAir PollutionDedicated Bus Lane[SDGs]SDG7[SDGs]SDG11thesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/50607/1/ntu-93-R91521506-1.pdf
