| Summary: | 碩士 === 國立臺北科技大學 === 環境工程與管理研究所 === 96 === This research uses questionnaires to investigate passengers’ opinions about the air quality in long-distance buses and the Taipei Mass Rapid Transit (MRT). Aspects stemming from the questionnaires include cognition and demand of in-vehicle air quality to understand passenger''s attention degree to this topic. The results of the questionnaires are further substantiated by in-vehicle monitoring. Methodologically, this research sets up an estimation model for measuring in-vehicle air pollutants such as CO2 concentration. An extensive survey was conducted to measure the in-vehicle concentration of CO2, CO, SO2, NO2, O3, TVOC, PM10, PM2.5, HCHO, temperature, and relative humidity. Concerning the routes of the targeted transportations, this research divides the routes of long-distance buses and Taipei MRT into three types of routes, respectively. The former is investigated in terms of the annual amount of loading in the northern, central and southern metropolises of the island. The latter is examined in terms of the operation routes that include ground, underground, and mixed level.
From the passengers’ questionnaire results, the air quality of "long-distance bus" and "city bus" is the worst. Besides, there is insufficient attention on in-vehicle air quality from the government. If the government positively coordinate to set up the improvement measures and regulations of in-vehicle air quality, over 60% of passengers would willing to cooperate with the government. The major pollutant is CO2 of in-vehicle air quality in long-distance buses and Taipei MRT, between 500 and 3000 ppm (the range of concentration is from 500 to 3000 ppm). NO2 and O3 are next important pollutants which are ranged between 0.05 to 0.46 ppm and 0.01 to 0.15 ppm respectively. The MAPE was used to verify the estimate and observation of CO2 concentration on in-vehicle air quality model, six monitored routes are less than 10%. CO2 is important index that influence the in-vehicle air quality, higher concentration leads to higher possibility of infection for susceptible. In order to protect passengers’ health, it should control the in-vehicle air quality.
