Accurate instantaneous vehicle emissions models are vital for evaluating the impacts of road
transport on air pollution at high temporal and spatial resolution. In this study, we apply …

Air pollution is a primary concern, causing around 7 million premature deaths annually, with
traffic-related sources contributing 23%–45% of emissions. While several studies have …

This paper presents a road vehicle emission model that integrates an artificial neural
network (ANN) model with a vehicle dynamics model to predict the instantaneous carbon …

Scientific research has demonstrated that on-road exhaust emissions in diesel passenger
vehicles (DPV) exceeds the official laboratory-test values. Increasing concern about the …

Numerous emission and air quality modeling studies have suggested the need to accurately
characterize the spatial and temporal variations in on-road vehicle emissions. The purpose …

Remote sensing provides a rapid detection of vehicle emissions under real driving
condition. Remote sensing studies showed that diesel nitrogen oxides emissions changed …

Data from portable emissions measurement systems (PEMS) and other sources have
allowed the discrepancy between type approval and real-world fuel economy and nitrogen …

Diesel NO x emissions have been at the forefront of research and regulation scrutiny as a
result of failures of late vehicle technologies to deliver on-road emissions reductions. The …

In real-world driving, most Euro 5 and 6 diesel passenger cars exceed the nitrogen oxides
(NO x) emission limits of type approval procedure. The emission factors of the fleet of Euro 6 …

NO X emissions from diesel light-duty-vehicles (LDV) largely exceed the Euro emission
standards in real-world driving conditions. Recent studies have quantified their impact upon …
