conducted between February 2009 and March 2008 at Suwon-Yeosu line in Korea. PM10 concentration level was 100㎍/㎥ on average. The PM2.5 to PM10 ratio in transport is 0.37, which was lower than the results published by other researches. The result also demonstrated that outdoor PM10 concentration was about 56~60% level compared to that of the cabin. CO2 concentration level in the cabin was 1,359ppm, which does not exceed 2,000ppm, which is the guideline concentration level according to the Ministry of Environment. CO2 concentration level in the cabin was CO2= 23.4 × N + 460.2, and about 23.4ppm in CO2 concentration level increased every time one passenger was added on. The experiment conducted on the train demonstrated that the average PM10 concentration level was 100㎍/㎥ in case of the reference cabin while average PM10 concentration level of the modified vehicle was 68㎍/㎥. Likewise, effect of the particle reduction device for the reduction of PM10 concentration level was approximately 21%. Meanwhile there was almost no difference in the concentration level between reference and modified cabin in case of PM2.5. Using zeolite as an adsorbent was made to reduce the CO2 concentration level in the cabin. Number of passengers was factored in, to calculate the effect of the adsorption device, which demonstrated that about 36% of CO2concentration level was reduced in the modified cabin effect of the CO2 reduction device. This research analyzed the current status concerning the quality of air in the public transportation and technologies were developed that reduces major air pollutants.
