| Summary | Global climatic change calls for effective programs for reducing emissions of greenhouse gases from all countries worldwide. For effective and efficient implementation, environmental considerations should be incorporated at the planning stage. The Institute of Transportation (IOT) has made considerable efforts in building travel demand forecasting models for evaluating transportation projects in economic terms. Incorporating environmental factors for evaluating effects of transportation policies on fuel consumption and air pollution, however, requires more research efforts. This study continues the efforts of the project entitled, ‘A Study on the Correlation Analyses between Energy Consumption, Emissions and Transportation Planning’, which established a relationship between fuel consumption/green house gas emission rates and traffic operations factors of small automobiles. The objective of this study is to further enhance the functions of the Taiwan Intercity Transportation Demand Forecasting Model by integrating a module of fuel consumption and green house gas emissions by building similar modules for buses. The target of the research is to establish a comprehensive mechanism for evaluating the environmental impacts in the process of highway planning, so that the policy goals of sustainable transportation, including efficient fuel usage and reduction of air pollution, may be achieved. The study made the following contributions in 2010: The project team made use of the new technology of an On-board Emissions Measurement Systems to investigate real-world bus emissions regarding energy consumption and pollutants when operating on various classes of highways. The project team collected intercity-bus on-road data to establish relationships between fuel consumption and vehicular speeds by highway classes. The focus of the first year of this two-year research is on the energy efficiency performance and hereafter CO2 emissions of intercity buses. The project team will continue the research efforts in the second year by collecting city-bus emission data to complete the bus model that is applicable to Taiwan’s traffic operating environment. |
