Abstract The escalating fuel price in Taiwan has prompted the transportation industry to explore renewable energy sources for fuels, but what is more urgent at this stage is to improve transportation efficiency to cut transportation costs. The aim of this study is to implement fuel-efficient rewards to modify driving behavior, thereby improving fuel efficiency. The outcome of this strategy is not only about slowing down greenhouse gas production, but also a reduction of fuel costs of transportation companies. Every year highway bus companies consume millions of liters of fuel, and their fuel costs often exceed hundreds of millions of dollars. Therefore, how to conserve on fuel consumption has become an important issue for all of the bus companies. However so far, besides the eventual fuel savings data, there is still a lack of objective methods to evaluate the execution of such conservation programs. the project will use the ¡§Motivation-Opportunity-Ability Method¡¨ ¡]MOA¡^to develop an analysis model; verification of dynamic data analysis will be conducted using Single or Multilevel Structural Equation Modeling (Multilevel SEM). According to the above research results show that Taken together the investigators suggest those public as well as private transportation companies that have not implemented fuel-efficient related policies to start planning fuel-efficient reward programs and implementing the programs as soon as possible. Furthermore, transportation companies should give courses about environmental driving to teach drivers correct environmental-friendly driving as well as award or publicly praise fuel-efficient drivers. These strategies will bring good outcome for drivers, transportation companies, and environmental protection.

Esta dissertação propõe um método de análise dos eventos de aceleração dos motores e dissipação de energia através do uso dos freios aerodinâmicos na fase de descida das aeronaves Boeing 737 NG da VRG Linhas Aéreas, baseando-se nos conceitos de energia, de aproximações em descidas contínuas e desenho dos procedimentos de chegadas, revisando as bases das práticas de conservação de combustível e dos sistemas de garantia da qualidade das operações de vôo. Foram analisadas mais de 130.000 descidas em um período de nove meses, durante a operação normal da empresa, através de leitura de dados dos gravadores de vôo que resultaram, após aplicação de algoritmos matemáticos simples e filtros, em mais de 314.000 eventos isolados. Estes eventos foram tratados com uma visão estatística, permitindo a quantificação financeira dos eventos através da proporcionalidade da variação de combustível consumido e energia agregada ou dissipada da aeronave. Os resultados obtidos através do método apresentado permitiram apontar as famílias, séries e prefixos de aeronaves com diferentes desempenhos nas descidas, as cidades de destino e rotas com desempenho baixo quanto a conservação de combustível e energia, assim apontando os possíveis caminhos para a empresa focar esforços na redução do custo de combustível. / This paper proposes a method of analysis of fuel consumption and energy dissipation events, as a consequence of engines acceleration and the use of speed brakes during the Boeing 737 NG descent segment of VRG Linhas Aéreas, based on the concepts of energy, continuous descent approaches and design of arrivals procedures, reviewing the basics of fuel conservation practices and flight operations quality assurance systems.There were analyzed more than 130,000 descents in a period of nine months, during the company normal operation, by reading data from flight recorders that resulted in, after the application of simple mathematical algorithms and filters, more than 314,000 individual events. These events were treated with a statistical view, to quantify the financial impact of this events through the proportionality of the variation in fuel consumption and energy added or dissipated by the aircraft.The results obtained using this method allowed to understand families, series and tail numbers of aircrafts with different performances on the descent phase, the destination cities and routes with poor performance in energy and fuel conservation, thus indicating a possible focus to enhance efforts to reduce total fuel costs.
