Title DEVELOPING AND VERIFICATION OF FUEL CONSUMPTION MODEL FOR HEAVY PASSENGER BUS ON FREEWAY NO.1
Author Po-Chun Chen、Zi-Ying Wu、Ting-Wei Liao、Yi-Chin Hu、Yi-Cheng Chang
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. Incorporating environmental factors for evaluating effects of transportation policies on fuel consumption and air pollution, however, requires more research efforts. And, in the past, the energy consumption/emission model constructed at the average speed of laboratory observations will not be sensitive to the energy saving and carbon reduction effects of strategies/measures that focus on improving the rate or improving operational efficiency.
The study team used the new technology of On-board Emissions Measurement Systems to collect about 5.7 thousand seconds of emissions data, which are used for building relationships between fuel consumption and instantaneous operating speeds of freeway bus. The National Freeway No.1 model established this year covers the slope range from -2% to 2% which occupied 90% of National Freeway No.1’s segments. Through the verification analysis, the estimate error is within 10%, indicating that this model has good estimation ability. Moreover, the CO2 emissions can be measured by transition coefficient. Based on the calculated fuel consumption and CO2 emissions of modes, we can evaluate the energy saving and carbon reduction effects on shifting passengers from cars to buses.
