The continuous release of pollutants has posed a significant threat to both public health and the sustainability environment. Consequently, governments across globe have introduced more stringent rules pertaining vehicle emissions address this issue. In addition, Portable Emission Measurement System (PEMS) is now most widely used approach for detecting NOx PN from heavy-duty vehicles on real roads. However, technology associated with requirements in terms human labor resources, making it expensive time-consuming. Hence, imperative put up novel surveillance actual on-road emissions. Prior research indicated potential employing soft sensors as an alternative physical purpose CO2 monitoring. there exists scarcity scholarly investigations monitoring PN. present study presents sensor based combination genetic algorithm (GA) gated recurrent unit (GRU) real-time nitrogen oxides (NOx) particle number (PN) within on-board diagnostics (OBD) system. This addresses existing gap development specifically designed study, we evidence that described exhibits exceptional R2 values outperforms other conventional models. Our findings illustrate operate by effectively eliminating outliers accurately promptly consistently tracking predictions over lifespan vehicle. Moreover, our model high degree reusability domain prediction possesses addressing emission emerging gas pollutant constituents forthcoming times.
