The purpose of this study is to develop correction formulas using the results of measurement by PMS 103, whichis a weight method measuring device, and by Dusttrak (TSI, USA), DustMate (Turnkey Instrument Ltd., UK),and LD-5 (SIBATA, Japan), which are light scattering measuring devices. The objective is to evaluate and identifynew standards (to develop a proposal) in order to complement the limitations of the existing measurement methodsof public transportation vehicle indoor air quality by utilizing the three nephelometer type measuring devices. Inthe case of non-rush hours, the PMS values were estimated using an estimation regression equation. Statistically,the PMS values that were actually measured were not significantly different (p-value=0.4375, 0.4375, 1.000). Withrespect to the agreement between the two values, ICC was 0.99 in the case of the estimation regression equationusing LD-5 values, 0.97 in the case of the estimation regression equation using Dusttrak values, and 0.84 in thecase of the estimation regression equation using DustMate values to allow for the identification of agreement atgreater levels. In the case of rush hours, the PMS values were estimated using an estimation regression equation. Statistically, the PMS values that were actually measured were not significantly different (p-value=0.3125, 0.6250,0.8125). With respect to the agreement between the two values, ICC was 0.92 in the case of the estimationregression equation using LD-5 values, 0.91 in the case of the estimation regression equation using Dusttrak values,and 0.89 in the case of the estimation regression equation using DustMate values to allow for the identificationof agreement at greater levels.
