Analyze the optimum control strategy for the mobile source abatement in Metro-Taipei

摘要

In order to control increasing ozone problems in urban areas, the adequate mobile sources abatement strategies based on cost effectiveness principal is the focus. MIR (Maximum Incremental Reactivity) scale is one of the popular reactivity scales for quantifying ozone impacts. This study considers different control cost and optimization method to achieve the maximum MIR reductions. According to the demands of decision-makers, mobile motors were divided into nine categories. Emission factor and VKT (vehicle kilometers traveled) of each motor were estimated by MOBILE5B with local parameters and odometer recordings. CNG and I/M were the alternative control measures for bus and touring bus. LPG, I/M, Methanol, EV were feasible abatement measures for taxi and low duty gasoline vehicle. EV, Methanol and I/M were the possible measures for 2-stoke and 4-stoke engine motorcycles. I/M was the alternative measure for low-duty diesel truck, heavy-duty diesel truck and low-duty gasoline truck. For different control cost, results show the best combination of control measures with optimization method in Metro-Taipei.
