운행 경유차용 다차선 매연 원격측정기(RSD) 실증 개발 및 현장 적용성 연구 = A Study on the Development of Multi-lane Smoke Remote Sensing Device(RSD) for In-used Diesel Cars and Possibility of Field Applicability

다국어 초록 (Multilingual Abstract)

A smoke RSD for in use diesel vehicles, which is applicable on multi-lane roads, was developed by applying a light transmission-type smoke concentration measuring module. The effect of interference on the driving lane factors and other factors related to the preceding vehicle, which were expected to be causing major errors, was analyzed. A high positive correlation of the smoke RSD for a single vehicle was verified (R2=0.811), and no significant measurement bias was observed based on the vehicle’s driving lane. The preceding vehicle caused significant interference, and it was observed that the amount of interference increased as the preceding vehicle decreased in speed, while the driving lane difference increased between the preceding vehicle and the following vehicle. Thus, reasonable smoke RSD regulation criteria must be established to minimize the error non-conformity rate by conducting error correction through the quantitative contribution analysis of each major error factor.
