Abstract
The current official emission database, TEDS 5.1 , estimates the emission of line-source by fuel-consumption method and distributes the emission by length and area proportion of the road in space. This kind of estimation is suitable for long-term and large-area but insufficient analyzing ability in time and space. This study analyzes the traffic data to estimate the emission by average driving speed, car density, and vehicle kilometer traveled (VKT) of each road. The space distribution of the estimation reflects the actual car current, and the time distribution also conforms to the driving pattern by analyzing the traffic data. The total emission of the line-source in Taipei estimated in this study about 60% to 80% over predicted to TEDS 5.1 in the downtown; underestimated in the suburbs. Through the simulation of Industrial Source Complex models (ISC) and Taiwan Air Quality Model (TAQM), there is higher R square in the scatter plot of the simulation result of this study and the monitoring value. According to the contours, the difference between these two ways makes different ozone concentration distributions in the outside of Taipei after conveying and diffusing by atmosphere for several hours. The time serious concentration plots of the simulation result of TAQM and the monitoring value show the simulation result corresponds with the monitoring value varying pattern. The simulation result of TEDS 5.1 evaluates higher ozone concentration in high ozone concentration episode.
